24 Nov 2011 imdisp Display multiple images as a montage of subplots Author: Oliver Woodford

Hi
This tool is better than Matlab's montage. as it can display images unequal in size. Is it also possible to display such images in a standard size, instead of displaying in their truesizes? Because the small image displayed with a tall image looks unappealing for comparison.

thanking you

21 Oct 2011 K nearest neighbor search Lightning fast k nearest neighbor search, yet very simple. Author: Michael Chen

Dear Chen,
Can you help add the feature of chi-square as metric, instead of euclidean distance.

with regards,
Ramana

21 Oct 2011 Efficient K-Nearest Neighbor Search using JIT A small but efficient tool to perform KNN search Author: Yi Cao

Dear Cao,
Your code is amazingly fast.
Can you help change the metric from euclidean distance to chi-square.

06 Oct 2011 Scenes/Objects classification toolbox Scenes recognition toolbox for vision systems Author: Sebastien Paris

Dear Sebastian,
I was using your extract_bag_of_features.m for my object classification. If possible, can you help me in following problems I am facing...
1. For a database of size 50,000 samples, there is Out of memory problems coming...
2. Can I use the dictionary built on one database, for encoding another database(s). I will normalize all images to a standard size of 50x50 and keep the SIFT parameters also the same.

thanking you,

with regards,
Ramana

20 May 2011 EM algorithm for Gaussian mixture model EM algorithm for Gaussian mixture. Works on arbitray dimensions with high speed and precision. Author: Michael Chen

Dear Chen,
Very good and fast implementation.
I guess the normal distribution you are using is exp( -(x-mu)^2/2*sigma^2 )/sqrt(2*pi*sigma^2)

In that case, if I were to slightly modify the sigma by w*sigma(or mu by w*mu), where 'w' is another design parameter, Can you help me which functions I need to change to utilize your code.

Thanking you very much.
