I just want you to understand that there are deeper levels of knowledge than the usual intellect (logical mind), and as long as you don't accept this, we will have a difficult communication. I don't want to argue on your level of knowledge, because I know it is deficient. My source of knowledge is a different domain, and difficult to communicate to someone who doesn't accept this. > (* filtering in an LTI sense requires interaction across blocks > if you want to avoid blocking artefacts ) I have a great problem with your notion of "filtering". I consider it a great source of evil in signal processing, as it is currently done. My experience tells me that it is often done wrong. And, as said, I have no problem with blocks, as I have no problem with pixels of digital images. To place a practical example, which might lead a bit off-topic but is to the point in my opinion: What do you think of the digital images taken by conventional digital cameras, say 99% of them (no matter if JPEG coded or not)? Your answer to this question would be quite revealing. If you somehow accept those results, as the majority of people which are clueless do, then this tells everything and we could stop to argue. My answer to this question is: All these digital images and digital cameras are crap, unacceptable. The production of that whole industry is just junk, trash, worthless. And the primary reason for this trash is the filtering of the crippled mosaic sensors. There is only one single camera manufacturer in the world which does not use that crappy filtering technique and produces true digital images, that is Sigma with non-filtering Foveon sensors. Everyone else uses this crap and produces fake digital images. Why do they use this crap? Have you ever asked? Why don't you go there and tell them that what they do is bullshit, instead of telling me what filtering may be good for? Look, that's why I don't argue with you about filtering. As long as you accept that people make such horror with filtering, I cannot take you seriously. I cannot take anyone seriously who accepts such nonsense. ciao human
