Effect of tiling in image compression using wavelet transform & hybrid wavelet transform for cosine & kekre transforms

Abstract

Image Compression plays more important role in reduction of size of graphic file without degrading image quality. Wavelet Transform & Hybrid Wavelet Transforms are proven to give better quality of compressed images. The paper attempts checking of effect of tiling on the performance of image compression methods using orthogonal transform their wavelet transform & hybrid wavelet transform. Experimentation is done on test bed of ten images of size 256 * 256 each. The results have shown that tiling improves the performance of image compression. The wavelet transform gives better quality of compression than orthogonal transform. Overall the hybrid wavelet transform gives better quality of compression when applied on 10 non-overlapping tiles of images.
