The purpose of this study is performance analysis of modified DA DWT1-architecture and Advance Lifting scheme architecture for Image Compression techniques.The information of the form image or video are transmitted as an array of data in terms of signal.Due to limited channel bandwidth, the data is compressed which in return reduces the quality of the image.An algorithmic concept of encoding information is given by wavelets in a manner that is layered according to level of detail.The analysis of this implementation includes speed optimization, accuracy, and power reduction.This study uses modified DA and optimized lifting based scheme, and architectures are modelled using digital systems, which is used for studying different performance on compressed image data.The study was done using signal simulation tool and VLSI cad tools.By implementing the proposed algorithm and modelling the architecture for image compression using DWT, we analyzed the timing wrt clock speed, area consumed and power consumed by both the architectures.Our study shows higher speed can be achieved by using DWT and better encoders for image compression and system can be modelled using digital systems, the study can be optimized to any further extent.
