Since the development of internet and multimedia, image compression is emerging in all the fields like pattern recognition, image processing, system modeling, data mining, etc. Compression techniques have become the most concentrated area in the fields of computer. Image compression is a technique of efficiently coding digital image to reduce the number of bits required in representing an image. Many image compression techniques presently exist for the compression of different types of images. In this paper, Vector Quantization based compression technique is established with Modified Fuzzy Possibilistic C-Means (MFPCM) with repulsion. Repulsion technique aims to reduce the intra-cluster distances and also increases the inter-cluster distances. The residual codebook is used in this proposed approach which eliminates the distortion in the reconstructed image and thus enhancing the image quality. Moreover, the proposed technique replaces LBG algorithm with the modified fuzzy possiblistic c-means algorithm in the codebook generation. Experimental results on standard image Lena show that the proposed scheme can give a reconstructed image with higher PSNR value than the existing image compression techniques.
Face recognition and retrieval is developed into a very active research area specializing on how to extract and recognize faces within images. The various methods has been proposed for face recognition and retrieval each methods has advantage and drawbacks. The complexity in process will affects performance of the existing system make insufficient. In this paper presented a Fiducial Point Feature based segmentation of face image in the generation of feature sets. The feature set is generated based on the fiducial points such as eye brow, eye, iris, mouth and nose are extracted and segment the image based on rectangular features. The feature is generated and matching is done by Euclidean distance is used to measures a distance between two images. The experimental result shows that Fiducial Point Feature method provides better recognition rate when compared with the existing methods such as PCA and PCA with DWT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
