摘要：The digital image processing is an innovative current research trends are more vital in the area of image compression for various imaging applications. These compression applications require good visual quality in processing. In general the substitution between memory efficient, compressio n efficiency and picture quality is the most important parameter to the newly proposed work. All type of images require to large amounts of space seems to be a big disadvantage during transmission and storage. There are many numbers of image compression te chnique already developed. These proposed applications involve digital image compression processing approaches for reduce the image volume. The Discrete Cosine Transform is commonly used in image compression technique. Redundant information in an image nee ds to be eliminated by adopting intellectual method. In the recent research attempts better quality of compression is observed with the use of Discrete Wavelet Transform (DWT) and Quantization. The objective of this proposed method is Effective Discrete Wa velet Transform (EDWT). The compression algorithm is concerned with compressing image with low level of data loss in the process. The compression algorithm is used to calculate the Compression Ratio (CR) in an image. The newly proposed compression image sh ows the table in various different sample tested images. The experimentation has been carried out on various sample test images successfully. The newly proposed system is an effective compression method is achieved and considerable test application for the quality of process in an image
