Hello all, I'm Bushra and I'm a newbie in this field. I'm doing a mini project with the Neurology Clinic here in Vancouver. The clinic takes MRI scans of patients and each slice in the MRI is stored in a file of the extension *.fil (proprietary GE format). Now the technician delivers all the *.fil files of all patients dumped in one tape to the clinic. The

hello, i am working on image fusion and i am using neural network and wavelet transforms method for this. i have lot basic doubts about 2-D wavelet transform of images and how algorithms have to be written.if any one has got any literature dealing with fundamentals of 2-D wavelets and algorithm please send it to me.

Hi, I am a newbie in this group, and I am working on a matlab project and the questions is as follows: "Select a variety of images or audio signal must be long enough, e.g., at least 10,000 samples) ?V called the designing or training set of signals. Use at least two different linear predictors to generate the differential signals. The

Hi, I am working on creating a GUI for opening images and then storing some pixel information which are selected by the user interactively (for this I am using a while loop with ginput function untill the user selects a point outside the image dimensions), this works fine untill the image is displaed at its true resolution. But, i have implemented zoom func

Hi! I am designing a 'P' Phase 'T' tap polyphase filter to implement video scaling. The way I am doing this is by designing a P*T tap filter in MATLAB and then splitting it into 'P' pahses 'T' taps each. However the contraint on this design is that each phase should have unity gain at DC so each phase should sum up to unity. However when I try to

Say I take an image, apply a (possibly fractional) pixel shift to it and further corrupt it by white gaussian noise. Is there any way (never mind complexity, to begin with) to estimate this shift using the corrupted image? Thanks!

Hi all: I have been working with the TI DM642 trying to develop a block motion search algorithm for a temporal filter in video. I have written a fast four step search in which I halved the step every time I searched a window of 5x5 blocks. I started with a step of 16 pixels and I ended up with a step of one pixel. After I found that minimum distortion, I used half pixel resolutio

I am looking for an image comparison algorithm. I need to compare two RGB images (24 bits per pixel) considering a mismatch percent. If the first image is lighter than the secound one them they has to be consider as equal images. Can anyone help me? pablin pplantero@ppla...

Hello All, I have a doubt about H263 How can I find out the macroblock boundaries with in a GoB of H263 bitstream?? Does a Block / Block data with in a macroblock have a fixed size?? So that I can calculate size of the first macro block and advance to the next one and so on?.. could any one help me on this.... Thank
