Image segmentation & Extraction

Really good

Well done.
The contour detection is good.But I am confused what does the last figure intend to show?

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);

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.

Thanks Jeny! Simple and useful

thank you

Simply Padam... ok Good

i tried to run it but i get this error
??? Error using ==> conv2
First and second arguments must be single or double.

Error in ==> seg at 20
B=conv2(BW,msk); %Smoothing image to reduce the number of connected components

thanks

Good work!

This is goooooood!

This is a gud one.

only reads your image. I tested with some other car images and your program fails.

HI

no

good

Dear Chris Shoemaker
I am working on the watermarking project in spread spectrum domain. I want to simulate it by matlab. can you help me about this?
thanks.

When i use quadtree program to segmente my grayscale image, i get in the result a binary image segmented!, can you help me to obtain a grayscale one.

thanks

thank

I think you should connect all the commands that are needed, for example I am not able to run it because I dont have command rgb2gray and others

ravings

helpful

goood software...

good

gr8 it worked for me ...

i got ant error in this
??? Attempt to execute SCRIPT edge as a function.
Error in ==> car at 11
BW = edge(im1,'sobel'); %finding edges
can u help me find out what is problem, thank you

good

sorry i'm a complete idiot, it does what it's supposed to. Ignore the last comment!

hi, I can not download it?!!!

its working fine, great. is there any technique to find automatically ROI. I am working on fingerprint compression.

What if I want to extract the plate from image of high resolution.
Also I want to extract the whole frame from the image.

Dear Jenny rajan,
here in my case first i need to read an image from the expm then need to normalize the concentrations in the chamber from 1 to 0, 1 for brighter image and 0 for dark they are black and white and to compute the standard deviation along some lines perpendicular to the chamber axis to see the mixing in that chamber. how to write a program to calculate this. Your feed back will be highly appreciated. Thanks in advance

well good work

its good idea but not so general since the number of the connected labels can be change and the id i think should be added information of shape of digits for improvr rate of recognition

I'm truly baffled why this poorly commented, poorly coded, piece of ad hoc code is the third most downloaded in the last 30 days. It just must be self perpetuating - people see it at the top of the list and download it so it stays at the top of the list. It is so bad in too many ways to list. The author clearly doesn't know how to use the Image Processing Toolbox functions. If you want a much, much better image segmentation demo/tutorial, check out this one:

plzzz send me a matlab code for image segmentation using morphology.......plzzzz somebody help me...

please dont forget me...my mail id is..... benabdel1984@hotmail.com
thanks

i am trying to segment the image of signature
is it possible to apply the same code ? if not ,, can anyone help me plz
thank you
