How to Store Pixel Intensity Values in Image Sequence
Hi, all, For each pixel in each image of a sequence of 15 images, I need to store its RGB intensity values so that if I want, I can plot any pixel's R, G and/or B's intensity values across the sequence. I've been reading about structs and cells and vectors, but I am not sure what is best to use. Hope this m... 8 Jun 2010 18:20

Mesh with non-uniform grid looking down onto x-y plane
Hi everyone, I am trying to create a mesh of a surface using equally sized squares, instead of stretching the squares as is done by using mesh or surf functions. Therefore, looking down onto the x-y plane, the surface will be able to be 'visualized' by the size of each of the squares (The squares on flat surface... 9 Jun 2010 17:34

an older version MATLAB function
Dear support team I am trying to run an older version of MATLAB M-file using MATLAB 2010. The function "chknl" is not defiened in this new version. I would like to know what does this function do. Best Regards Hamed Osouli ... 21 Jun 2010 09:07

adaptation of the size of plot objet
Hello, I develop a graphical interface with Matlab. I use two different tool to create visible point in the principal figure: - the tool fill or patch to create square - the tool "plot" to create objet of different shape (star, hexagone, circle,...) My problem is : when I zoom on the figure contening all the ... 17 Jun 2010 11:09

Position of MR slices
Hi all I have datasets of MR images in the DICOM format. I would like to know where the slices in the transversal plane are (position and orientation in the patient). An example is shown by clicking on the following link: http://250kb.de/ECU8XPt Any suggestions? Thanks, Michael ... 8 Jun 2010 03:39

trying to understand the kmenas result
Hi, I have a 2D picture which, in general, looks like 3 hills with 2 valleys in between (there is no full seperation between the hills). When running the 'kmeans' function with 3 clusters, I expected the Matlab to identify each "hill" in a different cluster. However, the picture was partitioned into 3 horizontal ar... 8 Jun 2010 03:39

Parallel Port can't get value
I connect two computers (A and B) with the parallel port. I utilize Data Acquisition Toolbox to send information from A to B. When I put value (putvalue) on the lines by entering commands at A computer, I can detect the potential changes of lines with electric meter. But the other computer cannot detect the potenti... 9 Jun 2010 04:15

2D gaussian fitting using Surface Fitting Tool
I'm trying to fit a 2D gaussian to a surface using the Surface Fitting Tool. I choose the custom equation option and enter this formula: A*exp(-x^2/(2*sigmax^2)-y^2/(2*sigmay^2)) I think that either my equation is wrong or I am not using the Surface Fitting Tool properly because it generates a flat surface that do... 16 Jun 2010 22:07

Normals and Multi-threading
Hello Friends, I have a morphological image. It has a white body(amoeba shaped) on a black background. The actions that I want to perform on this image are as stated - 1) Track the contours of this body. An efficient algorithm suggestion for this. 2) Study the contrast at each contour pixel in the perpendicula... 8 Jun 2010 01:28
