question about bwperim
Hi there - I'm wondering if there's a way to set the output of bwperim to be more than 1 pixel thick. I could do a loop over the boundaries to get each coordinate to be thicker so that I can emphasize the segmentation boundary. However sometimes I have many cells in one frame and it takes a long time to plot them. I... 20 Jul 2010 17:58

How to create motion model?
Hello all. I'm trying to learn the super-resolution reconstruction, but I have a problem on the motion model. The equation that describes the model is: f(k) = M(k, i) f(j) + e(k, j) Where f(k) and f(j) is the vectors representing frames at the k-th frame and the j-th. The matrix M(k,j), with size M x M which ... 20 Jul 2010 15:46

textread: whitespaces help!
I am trying to import several files that are 90 lines by 720 Columns (90X180 in i4 format). The data is sporadic and the file contains many blank spaces. When I import the file using textread, even with a specified format, it clumps all of the data to the left side of the matrix. If the data was simply numeric thi... 21 Jul 2010 13:33

Segmentiation of hair from skin
Hello everybody, I am working on a small assignment where I want to separate a hair from the skin. I have a high resolution input video sequence which has skin and hairs. So we can see atmost 3 to 4 hairs in a single frame. I have performed some morphological operations with thresholding to get 80% of accuracy but s... 5 Aug 2010 08:01

Resampling/Interpolation issue
Is it possible to resample data without having a rate multiplier composed of a rational ratio of two integers? If I were to use the resample function in MATLAB, it asks for p and q to be integers. I have looked at other interpolation and sampling functions and all of them at least ask for a rational number to multipl... 20 Jul 2010 16:51

On the ~ symbol in a function call...
Hello all. Sorry, this is more of an improvement request than a call for help - but thought it might be useful for some people to know... I noticed recently that you can call (in R2010, at least) a function using the syntax: [~, output_args] = someFunction(input_args). In a trivial example, the following ... 30 Jul 2010 17:27

Matlab memory error
Hi everyone, I've put together a GUI for my research lab that analyzes Gait data. What I'm doing is loading text files of raw data, segmenting the data into strides, and then separating the stances (all automatically). Things were going very well, until I tried loading larger files. I'm running the 32 bit ve... 20 Jul 2010 15:46
