STW and SPIHT Wavelet compression using MATLAB wavelet Tool for Color Image

Images can be represented by mathematical function using wavelets. Wavelet can be manipulated (shrink/expand) by applying some values to its function. It helps to localize the signals. Application of wavelet in images processing has larger scope as proved. Image compression is one of the dimension. There are various wavelet image compression techniques. This research paper focused on comparison of only two techniques i.e. STW and SPIHT for color JPEG images.
