Title Proper : A MODIFIED HYBRID DCT-SVD IMAGE-CODING ALGORITHM
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Today's image compression technique is experiencing many improvementsunder the method of transform coding. Many research groups have developed theimage-coding algorithms that optimize bit rate and image quality. The objective of thisthesis is to propose the hybrid image-coding algorithm that combines discrete cosinetransform (DCT) with singular value decomposition (SVD). A decision criterion as tothe choice of DCT or SVD is standard deviation (STD) of the 8 x 8 blocks of the image.DCT is used to transform the high correlation or low standard deviation 8 x 8 blocks.SVD is used to transform the low correlation or high standard deviation 8 x 8 blocks.Adaptive multistage vector quantization (AMVQ) is used to encode the eigenvectors ofthe 8 x 8 blocks of the image using SVD.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
