hi
u seem to have lot of doubts in image processing.
transformation applied to a image helps in extracting the hidden features of the image. ex: consider a normal image,applying negative transformation to that image gives you a negative image in which u will be able to get the boundaries of...
Re: DCT vs Wavelet
on applying DCT to an image u will have the DC component accompanying in the analysis side which will create problems.
using DWT u will not get any such thinks and also the subband sampling helps in extraxtion of the features easily.
hi,
denoising is like subtracting a image with noise and ur original image without noise.
u can use various filters and check which one produces good SNR finally.
also u can apply wavelet transform for image denoising.
