In this article, we present a novel approach for effective segmentation of color images, by integrating the advantages of the YIQ and the Log Normal Distribution features. Log Normal Distribution is considered in this paper, for effective segmentation, by considering the pattern of the pixels. The proposed method entails less complexity and is thus can be used reasonably very well for realistic...

This paper proposes a watermarking algorithm based on correlation to authenticate image content. The original image is converted to YIQ space first, then subdivided into 8× 8 non-overlapping blocks. DCT transform is executed on each block. The watermark sequence is derived from certain low frequency coefficients. It is hided into the middle frequency DCT coefficients of another pseudo-randomly ...

Proficient Content Based Image Retrieval system is a much needed system for plenty of image retrieval supporting applications, which retrieve images more rapidly from giant image databases. Block Truncation Coding (BTC) is one of the prominent and simple techniques used most of the time. This method is built on color properties of an image for image retrieval. In this paper a novel Static Thepa...

The multilayer secured DWT-DCT and YIQ color space based image watermarking technique with robustness and better correlation is presented here. The security levels are increased by using multiple pn sequences, Arnold scrambling, DWT domain, DCT domain and color space conversions. Peak signal to noise ratio and Normalized correlations are used as measurement metrics. The 512x512 sized color imag...

A finger finding procedure has been presented to recognize the finger number of the hand gesture. The hand gesture is extracted from the stationary background and transformed into a binary image. The hue attribute, that is, the I value in the YIQ color space is used to extract the hand gesture shape. This attribute is not so sensitive to the light change and the other noises while catching the ...

--Image enhancement is one of the key issues in high quality pictures such as digital camera and HDTV. Since Image clarity is very easily affected by lighting, weather, or equipment that has been used to capture the image. These conditions lead to image may suffer from loss of information. In this paper a new technique is introduced to enhance color images with dim regions ,In this technique th...

In this paper, a monitoring system that can distinguish the normal behavior from abnormal ones based on trajectory of palm for supermarket is designed. Our system brings some traditional algorithms and insights together to construct a framework for a new field called Supermarket Monitoring. In this project, only the moving hands are considered. To fulfill the automated monitoring task, the self...
