Investigation of transform domain encryption.IWT encryption study.Study of chaotic Baker map permutation. The primary goal of this paper is security management in data image transmission and storage. Because of the increased use of images in industrial ...

In this paper, we propose a new feature extraction approach for face recognition based on Curvelet transform and local binary pattern operator. The motivation of this approach is based on two observations. One is that Curvelet transform is a new ...

Encryption techniques are usually employed to maintain the secrecy of the video streams transmitted via a public network. However, full encryption using strong cryptographic algorithms is usually not necessary if the purpose is to destroy the commercial ...

With the increasing needs in security systems, vein recognition is one of the important and reliable solutions of identity security for biometrics-based identification systems. The obvious and stable line-feature-based approach can be used to clearly ...

Recently, 3D display systems are getting considerable attentions not only from theater but also from home. 3D multimedia content development plays very important role in helping to setup a visual reality entertainment program. Lenticular ...

The aim of this paper is to develop an effective fuzzy c-means (FCM) technique for segmentation of Magnetic Resonance Images (MRI) which is seriously affected by intensity inhomogeneities that are created by radio-frequency coils. The weighted bias ...

New generation vessels are equipped with fire detecting sensors; however, fire may not immediately be detected if it is far away from the sensors. The fire process therefore cannot be recorded. A video-based fire alarm system is developed to overcome ...

We present a new end-to-end protocol, namely Dynamic Video Rate Control (DVRC), which operates on top of UDP and enables the adaptive delivery of layered video streams over the Internet. The protocol optimizes the performance on video delivery with ...

A new region filtering and region weighting method, which filters out unnecessary regions from images and learns region importance from the region size and the spatial location of regions in an image, is proposed based on region representations. It ...

This paper presents a novel data hiding scheme for VQ compression images. This scheme first uses SMVQ prediction to classify encoding blocks into different types, then uses different codebooks and encoding strategies to perform encoding and data hiding ...

Spatial relationships are important issues for similarity-based retrieval in many image database applications. With the popularity of digital cameras and the related image processing software, a sequence of images are often rotated or flipped. That is, ...

Recently, a chaos-based image encryption scheme called RCES (also called RSES) was proposed. This paper analyses the security of RCES, and points out that it is insecure against the known/chosen-plaintext attacks: the number of required known/chosen ...

Watermarking is used to protect the integrity and copyright of images. Conventional copyright protection mechanisms; however, are not robust enough or require complex computations to embed the watermark into the host image. In this article, we propose an ...

Most Content-Based Image Retrieval systems use image features such as textures, colors, and shapes. However, in the case of a leaf image, it is not appropriate to rely on color or texture features only as such features are very similar in most leaves. ...

This paper presents ''Round-Eye'', a system for tracking nearest surrounding objects (or nearest surrounders) in moving object environments. This system provides a platform for surveillance applications. The core part of this system is continuous ...

In 2003, Kim applied the discrete cosine transform (DCT) technique to propose a content-based image copy detection method. He successfully detected the copies both with and without modifications, and his method is the first to detect the copies with ...

Recently, Lin and Tsai proposed an image secret sharing scheme with steganography and authentication to prevent participants from the incidental or intentional provision of a false stego-image (an image containing the hidden secret image). However, ...

In this paper, we propose a novel data hiding technique for color images using a BSP (Binary Space Partitioning) tree. First, we treat the RGB values at each pixel as a three-dimensional (3D) virtual point in the XYZ coordinates and a bounding volume is ...

This paper describes an ownership identification method with gray-level or color ownership statements. The proposed scheme uses the theories and properties of sampling distribution of means to achieve the requirements of robustness and security. Besides,...
