Abstract

This search focuses on Image Data compression using different methods for data compression, three images are simulated for the data compression technique based on modified method, Huffman with local and soft threshed and three block size 4×4, 8×8 and 16×16. The second one is based on using the DCT discrete cosine transformation and discrete wavelet transformation DWT these methods are applied on the stroke brain images Computing tomography images after using the region based segmentation method to get the region of interest which is the stroke, Completing the process by calculating quality of image compression, five parameter are used , Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE), Compression Ratio (CR), Structural Similarity Index (SSIM) and Universeral Image quality Index (UIQI).
