15 Jul 2005	Sergei Koptenko	1) In Matlab R14(SP2) it gives: ??? Error using ==> conv2 First and second arguments must be single or double. Error in ==> seg at 17 B=conv2(BW,msk); %Smoothing image to reduce the number of connected components 2) What is the application of this program beyond the test image "car3.jpg" ?

13 Sep 2005	Wang Bin	Well done. The contour detection is good.But I am confused what does the last figure intend to show?
15 Oct 2005	mufid mufid	i used part of the porgram for detect license plate of the car but.. there many other object is there any one can help me to fill the other edge or object without effect the license plate?
07 Jan 2006	lissa anastasia	tq for the code.i try to run this code into matlab..but why the command 'imread' is going error?below is the error.. Enter the file nameseg.m ??? Attempt to execute SCRIPT imread as a function. Error in ==> Untitled8 at 7 im=imread(k);
13 Jan 2006	Xin Huang	too simple and meaningless. more complex examples need to be added. and objects extraction can be subdivided to supervised method and Un-su one, this code is an Un-su algorithm, can it extract all the objects of interests in an Un-supervied approach?

15 Mar 2006	Tony Gladvin George	As Mr.Sergei KOptenko indicated, line no:17 "B=conv2(BW,msk)" will throw an error. Please use "B=conv2(double(BW),msk)", instead.
04 Apr 2006	cool coolleen	i m doing my final year project of mini portions segmentation method in face recognition using matlab. may i know how to put my cropped small portions of the face into matrix (eg: 6x9 matrix, where 6 refer to number of photos, n 9 refer to the number of small portions). by the way, i also would like to know how can i compare the matrix column by column in order to get the eigenvalues. n i m new to matlab, so i hope u will help me to clear my doubts. if u have to source code, pls send a copy to me. thanks and really appreciate for your help. Hope can hear from u soon.
