Image downsampling with Haar DWT?
yes ok thanks for the reply. Specifically, what I intend to do is an algorithm of digital image processing for use in retinal implants. Clarifying a bit my problem I know that there is a mathematical operation applicable to digital images that is called Wavelet Transform and that is in some way to compress the image can also lower its resolution through downsampling. My question is how can I from Matlab (with wavemenu GUI for example) compress an image using the Wavelet Haar transform and lower its resolution for example 640x480 to 32x32. In the following article is explained in a general way in the last step of table 1
