ONE-DIMENSIONAL DWT AND IDWT ARCHITECTURE The goal of video compression algorithm is to achieve efficient compression with less loss. Most practical video compression techniques are based on the lossy compression, in which greater compression is achieved but decoded signal not identical to the original. Unfortunately, at the present time lossless methods can achieve only a modest amount of compression of image and video signals. Redundancy is removed so that the original signal can be perfectly reconstructed at the receiver. Keywords: Image compression, video compression, Discrete Wavelet Transform (DWT), Inverse Discrete Wavelet Transform (IDWT), Peak signal Noise Ratio (PSNR) and Compression Ratio (CR).

We also calculated the PSNR and CR values after image reconstruction using IDWT algorithm. In this paper DWT method applied for image and video compression.

Although Video looks like continuous motion, it is actually a series of still images. Fortunately, there are several methods of image compression available today. This is because the amount of space required holding uncompressed image costs more. Today compression is very necessary because dependency on computer increasing day by day.
