3d reconstruction
Hi everyone, I have a set of 2d images to be processed. These images comes from 3d dicom image. The outcome of this algorithm is to detect an area in each of the images. The problem is I want to reconstruct the detected area on each images to be 3d volume. how do i proceed for this reconstruction? thanks i... 16 May 2010 10:14

R square statistics problem
Hello folks, I'm need a little help about static toolbox. I have project to make, a regression analysis and i use "regress" - [B,BINT,R,RINT,STATS] = REGRESS(Y,X). I'm interesting in vat STAT, it returns R2 - stat, F - stat , variance err and so on. But i can't find how Matlab computes R2 - stat and F - stat and so... 16 May 2010 05:57

How to calculate image hash as a bit sequence of 0's and 1's
Hi All, I'm doing a research, which requires the hash value of an image to be calculated as a sequence of 0's and 1's (eg:- 11100101). Any standard algorithm MD5, MD4 or SHA would be fine in calculating image. If some one can help me or give some hints I would be thankful... Please Help! Thanks in advance... ... 7 Jul 2010 07:57

neural network training on quad core machine
Hi Everyone, I am trying to train a fftd network with a large data set (15000 by 10 input vector), 40 time delays, and ~30 hidden layer neurons. It's quite time and memory consuming, but I think I need to use trainlm due to better final training performance. I am doing a comparison of the different training functi... 16 May 2010 01:40

serial communication with 8051 controller
Hello.. I am working on a project in which i suppose to show temperature value on LCD. I am using 8051 microcontroller and interfaced LCD with it. As the temperature value is numeric so i am using 'fwrite' to transmit data. But to test serial communication first i used to tranfer string with the help of 'fpr... 19 May 2010 11:33
