نویسنده
چکیده
Image compression is a necessary technique for image transmission in a channel. In this paper, it is aimed to improve efficiency and dealing with the performance evaluation of image compression techniques for various kinds of images from uncontrolled environments. The key special of this paper is, the image compression is carried out using wavelet based image compression and decomposition techniques. SPIHT based image compression is proposed for achieving better image compression in high compression ratio. The simulation results of SPIHT technique are compared with the various existing compression techniques such as VD, DCT and DWT. All the technique used in this paper are implemented in MATLAB software and the performance is compared using the parameters such as PSNR, MSE, CR and compressed size.
