1 is a diagram illustrating an image generation system 1 for classifying and searching a photographic image based on location information according to an embodiment of the present invention. Referring to FIG. 1 , an image generating system 1 for location information-based photo image classification and search is a user terminal group 100g including a plurality of user terminals 100 , a network 200 , and photo image classification and search. It may include a server 300 and a big data server 400 .

The network 200 is a high-speed backbone network of a large-scale communication network capable of high-capacity, long-distance voice and data services, and may be a next-generation wired or wireless network for providing the Internet or high-speed multimedia services. When the network 200 is a mobile communication network, it may be a synchronous mobile communication network or an asynchronous mobile communication network.

Meanwhile, although the WCDMA network is taken as an example, it may be a 3G LTE network, a 4G network, other next-generation communication networks such as 5G, and other IP-based IP networks. The network 200 is a user terminal group 100g consisting of a plurality of user terminals 100, a photo image classification and search server 300 and a big data server 400, and other systems that mutually transmit signals and data between each other. plays a role

On the other hand, the photo image classification and search server 300 stores the terminal identification number (IMEI) of the user terminal 100 registered as an acquaintance among the plurality of user terminals 100, and retrieves the photo image corresponding to the same radius information. It is possible to store and manage photo images in which calligraphy and symbol images overlap as a directory on one database.

2 is a diagram illustrating components of each user terminal 100 in the image generating system 1 for location information-based photo image classification and search according to an embodiment of the present invention. 3 to 5 are user interface (User Interface, hereinafter 'UI') screens output to the user terminal 100 to explain the location information-based photo image classification and search method performed by the user terminal 100. It is a drawing for explanation.

First, referring to FIG. 2 , the user terminal 100 includes a transceiver 110 , a control unit 120 , a storage unit 130 , an input/output unit 140 , a location information providing unit 150 , and a photographing unit 160 . The control unit 120 may include a photo image collection module 121 , a photo image location classification module 122 , an emphasis and base color extraction module 123 , and a texture output module 124 .

The photo image collection module 121 stores the photo image taken by the user through the photographing unit 160 while the user engages in hobby activities such as travel or daily life with the user terminal 100 when the user terminal 100 is a mobile terminal. By controlling the transceiver 110 to be stored in the unit 160 or transmitted to the photo sorting and search server 300 through the network 200, a database for the user's own photo image can be built on a location-based basis can do.

In this case, when the number of photographic images increases, the photographed image must be systematically displayed according to the location of the user, and for this, the photographic image location classification module 122 may automatically classify the user image based on the location.

That is, the photo image location classification module 122 is a pre-stage of a system for displaying a photo image in the form of an illustration according to a user's location, and extracts latitude and longitude information provided by the location information providing unit 150 for each photo image. can do.

To this end, the photo image collection module 121 receives latitude and longitude information, which is location information of the photo image, from the location information providing unit 150 when each photo image is taken through the photographing unit 160, and receives the photo image in the form of metadata. can be included in Here, the location information providing unit 150 may be formed as a GPS receiving module, and for this purpose, the photo image collecting module 121 is an auxiliary means or a separate independent means for the GPS location information received from the location information providing unit 150 . As a result, location information may be further provided through base station-based triangulation through the transceiver 110 .

Accordingly, the photo image location classification module 122 is configured in advance of the location to which the location information (latitude and longitude information) included in the photo image stored in the database of the storage unit 130 or the photo image classification and search server 300 belongs. Calligraphy corresponding to radius information (km) and overlay images corresponding to symbols may be provided through a request to the big data server 400 through the network 200 . Here, since the locations included in the radius information (km) are classified into a grid with units of latitude 1 minute and longitude 1 minute, the photo image location classification module 122 is configured to display a column corresponding to the current location of the photo image in each grid. can be found

More specifically, in order for the photo image location classification module 122 to find a box on the corresponding radius information, the photo image collection module 121 stores each photo image in the storage unit 130 or the photo image classification and search server 300 . It may be stored in the database as a two-dimensional B-tree or using a hash map, and the photo image location classification module 122 may extract a cell to which the photo image belongs by utilizing the two-dimensional B-tree structure or hash map structure.

On the other hand, the photo image location classification module 122 includes a total of 9 spaces, that is, 3 minutes latitude, 3 minutes longitude, including 8 grids adjacent in the east-west, north-south, and diagonal directions on one radius information to which the location information of the photo image belongs. You can sort each photo image in order of distance by comparing the distance between all the saved location information in , and the location information of the photo image.

After that, if the location information of the user image is within one preset radius information, the photo image location classification module 122 registers the currently activated overlay image as that of the corresponding location and stops the search, and moves east and west around one radius information , it is possible to stop the search after comparing the location information with the user image up to other radius information adjacent in the north-south and diagonal directions.

The photo image location classification module 122 is stored in the storage unit 130 and/or the photo sorting and search server 300 for the overlay image after the search is stopped according to the registration, and then added to the highlighting and base color extraction module 123. Through a request to the currently active overlay image, it is possible to request to obtain a base color and an accent color for application to a photographic image.

The highlight and base color extraction module 123 may make the location information found by the photo image location classification module 122 in the form of calligraphy and/or symbols and insert it into the photo image in the form of an overlay image.

More specifically, the highlight and base color extraction module 123 determines the overall color of the photo so that the calligraphy and/or symbol shape inserted into the photo image matches the overall color of the photo image so that the calligraphy and/or the symbol shape match. An algorithm for determining a color and designating a color for calligraphy and/or symbol shape may be provided.

That is, the highlight and base color extraction module 123 automatically colorizes two different overlay images of calligraphy and symbols corresponding to the location information found by the photo image location classification module 122, respectively, to color the photographic image. We need to extract the "emphasis color" and "base color" from the "base color" is the color of the symbol to be inserted at the base of the photo image (see Fig. 5b), which should be darker than the color of the photo, and the "emphasis color" is the color of the photo It may correspond to the color of the calligraphy to be inserted at the top of the image (see FIG. 5B ).

First, the highlight and base color extraction module 123 extracts colors of pixels formed at a plurality of preset positions from the whole on one photo image. As shown in FIG. 3 , colors can be extracted from a total of 25 pixels. To this end, the highlight and base color extraction module 123 extracts colors from more pixels toward the center of the photographic image, thereby increasing the weight of the main subject of the photographic image in the representative color.

In FIG. 3, the highlight and base color extraction module 123 separates both ends from the vertical line set at the first interval on both sides in the horizontal direction with respect to the vertical center line and the first vertical line set at the first interval in a horizontal direction of 1: 1.5 to 2.5. It is divided by a second vertical line dividing by a direction length ratio, and the upper and lower ends from the first horizontal line set at the third interval and the first horizontal line set at the third interval in the vertical direction with respect to the horizontal center line are 1: 1.5 to 2.5 It can be divided by a second horizontal line dividing by a vertical length ratio of , and divided by diagonal lines on both sides.

Thereafter, the highlight and base color extraction module 123 sets one pixel at the point where the vertical center line and the horizontal center line meet, and sets the first vertical line, the second vertical line, the first horizontal line, and the second horizontal line in both diagonal directions. Set all 8 pixels at the point of intersection, set 4 pixels at each corner of the photographic image, set 6 pixels at the point where the horizontal center line meets the first vertical line and the second vertical line, and set the vertical center line and By setting 6 pixels at a point where the first horizontal line and the second horizontal line meet, when colors are extracted from a total of 25 pixels, a feeling of color of the overall photographic image can be extracted.

As such, the highlight and base color extraction module 123 may obtain the color average for each R, G, and B channel through the following [Equation 1] with respect to the 25 extracted pixels.

Thereafter, the highlight and base color extraction module 123 may adjust the brightness of the color average by using the following [Equation 2] by utilizing the color average of 25 pixels obtained in [Equation 1], and the brightness is The adjusted average color may be set as one color example as shown in FIG. 4A .

Accordingly, the highlight and base color extraction module 123 obtains the base color for the average color whose brightness is adjusted in [Equation 2] by using [Equation 3] below for each R, G, and B channel. The transmission/reception unit 110 is controlled to store in the storage unit 130 or transmit to the photo sorting and search server 300 through the network 200 , and FIG. 4B is a diagram illustrating the base color of FIG. 4A .

The emphasis and base color extraction module 123 adjusts the saturation of the average color obtained in [Equation 2] with the brightness adjusted using the following [Equation 4] together with the process of obtaining the base color, as shown in Fig. An average color whose saturation is adjusted such as 4c can be obtained.

Thereafter, the highlighting and base color extraction module 123 acquires the highlight color by inverting the hue through the following [Equation 5] with respect to the average color whose saturation is adjusted by [Equation 4], and the storage unit 130 The transceiver 110 is controlled to store in the , or transmit to the photo sorting and search server 300 through the network 200, and the acquired highlight color may be as shown in FIG. 4D.

Thereafter, the texture output module 124 converts three images for each R, G, and B channel corresponding to each of the "base color" and "emphasis color" obtained by the enhancement and base color extraction module 123 into one texture. After loading into the system memory formed in the controller 120 itself in order to implement it as a texture, it may be output through the input/output unit 140 .

Here, the texture output module 124 allocates one of the R, G, and B channels for up to three images, respectively, to the R, G, and B channels to implement the texture on the canvas of a preset size on which the overlay image is to be covered. By loading the values of three monochromatic images and setting the alpha channel to the sum of the alpha values of each monochromatic image, it is possible to reduce system memory usage by loading it into its own system memory. effect can be provided.

On the other hand, the texture output module 124 in the form of a texture in which calligraphy of the photo image corresponding to the location classified by the photo image location classification module 122 is assigned to the G channel on the system memory and the symbol to the R channel on the system memory. may be uploaded, and the uploaded texture may be as shown in FIG. 5A .

Thereafter, the texture output module 124 generates an accent color (Accent) obtained by the highlight and base color extraction module 123 at a point where the G channel is located, and an accent and base color extraction module 123 at a point where the R channel of the texture is positioned. ), a synthesized photographic image may be obtained by multiplying the basis color (Basis) obtained by . At this time, if the pixel color of the texture synthesized by the texture output module 124 is (Rt, Gt, Bt), the color of the pixel synthesized in the photo image can be obtained through the following [Equation 6], 5b is a diagram illustrating pixels synthesized in a photographic image.
