In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Fig. 1 is a flow chart of a video generation method according to some embodiments of the invention. As shown in fig. 1, the video generation method of this embodiment includes steps S102 to S106.
In step S102, an original image and a mask video are acquired, wherein the mask video includes one or more mask images.
The original image refers to an image used to generate video. For example, a product display video is generated using a product image as an original image, a personal introduction video or an electronic album is generated using a life photo as an original image, and the like.
The mask video is used to add video effects to the video generated from the original image. When a new effect is desired to be added to the video, only a new mask video needs to be generated or acquired, and a template special for a certain tool does not need to be made by writing a program or the like.
In some embodiments, one or more mask images may be generated or acquired, and then mask video including the mask images is generated. Each mask image may play one or more frames.
In some embodiments, the mask image is a binarized image. The binarized image includes only black pixels having a gradation value of 0 and white pixels having a gradation value of 1. For example, it is possible to determine which pixels are displayed and which are hidden in the original image based on such a mask image.
In step S104, for each frame of mask image in the mask video, pixel information of a pixel located at the same position in the processed image corresponding to the mask image is determined from pixel information of a pixel located at the same position in the mask image as the original image. The pixel information may be a pixel value, a gray value, an RGB (Red Green Blue) value, transparency, or the like. The type of pixel information can be selected by those skilled in the art as desired.
As shown in fig. 2, the pixels 210 in the original image 21 and the pixels 220 in the mask image 22 are located in the second row and the second column. When the original image 21 is processed according to the mask image 22, the pixel information of the pixel 230 in the processed image 23 is determined according to the pixel information of the pixel 210 and the pixel 220. The pixels 230 are also located in the second row and the second column.
In some embodiments, the above-described process may be implemented by invoking one or more interfaces provided by OPENCV (Open Source Computer Vision Library ).
In step S106, a video is generated from the processed image corresponding to each frame of mask image. That is, each frame in the generated video is a respective processed image.
In some embodiments, the process of generating video from the corresponding processed image of each frame mask image may be implemented by invoking an interface of FFMPEG (Fast Forward MPEG, fast forward MPGE, MPEG stands for moving picture expert group, collectively Moving Picture Experts Group).
By the method of the embodiment, the original image can be processed by using the mask video, and the video is generated according to the processed image, so that the automatic addition of the video effect and the automatic generation of the video can be realized. And moreover, the mask video is convenient to manufacture, and the learning cost and video manufacturing time of a user are reduced. Therefore, the efficiency and the applicability of video generation are improved.
Fig. 3 is a flow chart of an original image processing method according to some embodiments of the present invention. As shown in fig. 3, the original image processing method of this embodiment includes steps S302 to S304.
In step S302, pixel information of pixels at the same position of the mask image and the original image is subjected to a predetermined operation.
For example, the mask image may be multiplied with the pixel information of the pixels at the same position of the original image to process the pixel information of the original image proportionally according to the pixel information of the mask image; alternatively, pixel information of pixels at the same position of the mask image and the original image may be added to perform superimposition processing on the original image and the mask image. The manner in which the skilled person can select the operation according to need is not described here in detail.
In step S304, pixel information of the co-located pixels in the processed image corresponding to the mask image is determined based on the operation result.
In some embodiments, the result of the operation may be determined directly as pixel information of the processed image.
In some embodiments, the background image may also be superimposed on the basis of the result of the operation to obtain a richer video effect. For example, the sum of the pixel information of the pixel in the background image and the calculation result corresponding to the pixel at the same position may be determined as the pixel information of the pixel at the same position in the processed image corresponding to the mask image.
The background image may be other acquired original images, or may be an image obtained by processing other original images. An embodiment of the present invention for superimposing other images in processing an original image is described below with reference to fig. 4. In this embodiment, the mask image is a binarized image.
Fig. 4 is a flowchart of an original image processing method according to other embodiments of the present invention. As shown in fig. 4, the original image processing method of this embodiment includes steps S402 to S408.
In step S402, a first multiplication operation is performed on pixel information of pixels at the same position of the mask image and the original image.
Since the mask image in this embodiment is a binarized image, after the first multiplication operation is performed, the black portion in the mask image makes the pixel information of the corresponding position in the original image set to 0, and the white portion makes the pixel information of the corresponding position in the original image unchanged.
In step S404, pixel information of each pixel in the mask image is subjected to inversion processing to obtain an inverted mask image. That is, a pixel having a pixel value of 0 in the mask image is converted into a pixel having a pixel value of 1, and a pixel having a pixel value of 1 is converted into a pixel having a pixel value of 0.
In step S406, the pixel information of the pixel at the same position on the inverted mask image and the acquired other original image is subjected to a second multiplication operation.
Similar to step S402, after the second multiplication operation, the black portion in the inverted mask image causes the pixel information of the corresponding position in the other original image to be set to 0, and the white portion causes the pixel information of the corresponding position in the other original image to be unchanged.
Steps S404 to S406 may be performed before step S402.
In step S408, the sum of the first multiplication result and the second multiplication result corresponding to the pixel at the same position is determined as the pixel information of the pixel at the same position in the processed image corresponding to the mask image.
As shown in fig. 5, the pixel information of the pixels at the same position of the original image 51 and the mask image 52 is subjected to a first multiplication operation, and the operation result can be intuitively represented by a first operation result image 53; the pixel information of the pixels at the same position of the other original image 54 and the inverted mask image 55 is subjected to a second multiplication operation, and the operation result can be intuitively represented by a second operation result image 56. Pixel information of the pixels at the same position of the first operation result image 53 and the second operation result image 56 is added to obtain a processed image 57. In the mask image 52 and the inverted mask image 55, the dot-like background portions are black portions, and the non-dot-like background portions are white portions.
It should be clear to a person skilled in the art that the first operation result image 53 and the second operation result image 56 are only used to visually illustrate the processing procedure of the above embodiment. In the application process, the first operation result image 53 and the second operation result image 56 may not be generated, but only the operation results corresponding to the pixels at the respective positions may be stored.
The above-described embodiments are capable of displaying information of an original image or another original image according to different pixel values in a binarized image. In some embodiments, the other original image may be the next image to the currently processed original image, such that a smooth transition between different original images may be achieved in the generated video.
Fig. 6 is a flow chart of an original image processing method according to some embodiments of the present invention. As shown in fig. 6, the original image processing method of this embodiment includes steps S602 to S606.
In step S602, a preset operation corresponding to pixel information of a pixel of the mask image is determined.
For example, a correspondence relationship between pixel information and a preset operation may be established in advance. The correspondence may include a correspondence between a value of the pixel information or a value range to which the pixel information belongs and a preset operation.
In step S604, a corresponding preset operation is performed on the pixel information of the pixels at the same position of the original image.
In step S606, the result of the preset operation is determined as pixel information of the pixel located at the same position in the processed image corresponding to the mask image.
The above embodiment may also be processed in combination with a binarized image as a mask image. In some embodiments, in the case that the pixel information of the pixels of the mask image is a preset value, the corresponding preset operation is to replace the pixel information of the pixels at the same position of the original image with the pixel information of the pixels at the same position of the acquired other original image. For example, in the case where the pixel value of the pixel of the mask image is 0, the pixel information of the pixel at the same position of the original image may be replaced with the pixel information of the pixel at the same position of the other original image that is acquired; when the pixel value of the pixel of the mask image is 1, the pixel information of the pixel at the same position in the original image is directly used as the pixel information of the pixel at the same position in the processed image.
In some embodiments, the other original image may be the next image to the currently processed original image.
The above embodiments describe the manner in which any one of the original images is processed in the process of generating a video. Embodiments of the present invention may employ one or more original images to automatically generate video in conjunction with the methods of the above embodiments. An embodiment of the video generation method of the present invention is described below with reference to fig. 7.
Fig. 7 is a flow chart of a method of generating video from processed images according to some embodiments of the invention. As shown in fig. 7, the method of generating a video from a processed image of this embodiment includes steps S702 to S714.
In step S702, one or more original images and mask videos input by a user are acquired. An audio file entered by the user may also be retrieved as an audio track of the video, as desired.
In step S704, the size of the mask video is adjusted to the same size as the original image.
In step S706, the nth original image is processed using the mask video, which specifically includes: for each frame of mask image in the mask video, determining pixel information of the pixels at the same position in the processed image corresponding to the mask image according to the pixel information of the pixels at the same position of the mask image and the Nth original image.
The initial value of N is 1.
In step S708, the processed image corresponding to the one or more original images and each frame of mask image is taken as a set of video frames corresponding to the original image.
In step S710, it is determined whether N is equal to the number of original images, and if not, step S712 is performed; if so, step S714 is performed.
In step S712, the value of N is added by 1, and the flow returns to step S706 to process the next original image.
In step S714, a video is synthesized using a set of video frames corresponding to one or more original images. When the user inputs audio, it is also possible to synthesize audio into video.
By the method, the video with visual effect can be automatically generated through the original image and the mask video input by the user, so that the video generation efficiency is improved.
