everybody knows that in transform coding the image to be coded is at first converted in the transform domain.this transformation has two effects.first,compression and second,decorrelation. can anybody explain to me very precisely how this decorrelation helps anyway (preferably

Hi everyone, I am working on machine vision for a Lego robot. The aim is having robot to navigate around the room, based on digital camera output. (Sample photo is added to the Photos section). On this photo, I am trying to isolate the floor. Essentially I am try

Hi I am just learning image processing. I want to implement edge detection by sobel operator in 'c', i am facing some problems. i am first reading image. then i am applying first mask to it and gradient(let gx) in another veriable. now i am applying second mask to original imag

hi guys, since some weeks ago, I'm trying to find some software for processing image files (bmp, jpeg, etc, etc, formats) to a kind of txt tables (X Y RGB) and the other way round. By using tools like 'bmptoppm'and 'pnmtoplainpnm' it is possible to obtain such tables, but it still ha

HI everyone, I have a peculiar problem.I am trying to view the encoded bitsream produced by our H263 encoder on quicktime by attaching a quicktime header realtime. The qt files run fine on qt but if I try to drag the cursor at the bottom,after pausing it.The image goes

Greetings. I'd like to know your opinion about the subject for my undergraduate thesis. I'd like to implement algorithms for low-level image processing in different hardware plattforms (like FPGAs, DSPs, microcontroller, even the PC) and make a comparisson about p
