Scene Interpolation Based on Differential Pixel Color Comparison

Data Hiding Method Based on Graph Coloring and Pixel Block‘s Correlation in Color Image

An optimized method for data hiding into a digital color image in spatial domainis provided. The graph coloring theory with different color numbers is applied. To enhance thesecurity of this method, block correlations method in an image is used. Experimental results showthat with the same PSNR, the capacity is improved by %8, and also security has increased in themethod compared with other meth...

Comparison between Block-based and Pixel-based Temporal Interpolation for Video Coding

In very low bit rate (VLBR) video conferencing and videotelephony applications, the bit rate of sending video sequences must be kept low due to the limited channel bandwidth. To satisfy the VLBR requirement), temporal subsampling is a simple technique which may be combined with other compression schemes to achieve very large compression ratio. A previous proposed block-based motion compensated ...

Color Image Segmentation Based on Automatic Seed Pixel Selection

In this paper, we present color image segmentation based on automatic seed pixel selection. First, the input RGB color image is transformed into HSVcolor space. Second, the initial seeds are automatically selected based on non-edge and smoothness at pixel’s neighbor as criterion. Third, the seed pixels are merged to form seed region if they are connected. Fourth, a seeded region growing method ...

Skin segmentation based on multi pixel color clustering models

A Survey on Pixel-Based Skin Color Detection Techniques

Skin color has proven to be a useful and robust cue for face detection, localization and tracking. Image content filtering, content-aware video compression and image color balancing applications can also benefit from automatic detection of skin in images. Numerous techniques for skin color modelling and recognition have been proposed during several past years. A few papers comparing different a...
