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 past years have seen a rapid development in the area of image compression techniques, mainly due to need fast and efficient techniques for storage transmission data among individuals. Compression is process representing compact form rather than its original or incompact form. In this paper, integer implementation Arithmetic Coding (AC) Discreet Cosine Transform (DCT) were applied colored im...

The use of wavelets in the broad areas of source coding, communications, and networks is surveyed. Specifically, the impact of wavelets and wavelet theory in image coding, video coding, image interpolation, image-adaptive lifting transforms, multipledescription coding, and joint source-channel coding is overviewed. Recent contributions in these areas arising in subsequent papers of the present ...

In this paper, we discuss methods using the wavelet transform to compress digital images. These methods often employ common image coding strategies such as embedded coding, entropy coding, and subband decomposition, which are described in detail. Then we compare actual image coders that are used in practice based on metrics such as image quality, PSNR, rate scalability, and computational comple...
