Hi
I am working on scalable coding of images and videos. I do not quite understand
how DWT is performed on images (2D DWT). For image compression using Discrete
Cosine Transform, DCT is perform on each of the pixel values of Y, Cr, Cb
components before quantization and entropy coding. Does DWT works the same way?
(ie. performed on pixel values) Or is it a totally different process? Are there
any books or websites on the fundamentals?
