hi can anybody help me in coding 2d dwt for image processing. i have no idea about the transform. till now i`ve completed the entropy encoding, but i heard entropy encoding need to be applied for the results of transform during image compression.
is it really necessary to apply DWT for pixel values before entropy encoding. if so what is the reason behind it ??? pls let me know
