Image segmentation & Extraction

This program segments and extracts objects from an image.

Description

A simple program for object extraction from images.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 6.1 (R12.1)
• Other Files: seg.m, ; car3.jpg

[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" ?

[Ajimon S]

Really good

[Jagannath Reddy]

 

[Wang Bin]

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

[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?

[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);

[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?

[venkatesh sundararaj]

 

[boonrit pongsatitpat]

im=imread('car3.jpg');

[Alex Denone]

 

[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.

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.

nice work

[Benamira Elias]

Thanks Jeny! Simple and useful

[Simon Lin]

BW arguments must be single or double, if so, please update code.

[mohamed hassan]

thank you

Simply Padam... ok Good

[gaurav santhalia]

plz tell me what input should i give.here when it is asked to give input i give as car3...but there is an error...plz suggest me...

[a moh]

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

[kruthika rathinavel]

im getting an error == > conv2

[Özkan SARI]

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

[fucking crack]

You cannot start the m-file with clear all. It doesn´t work.

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.

[Soumen Barik]

 I think it will help us in our project..

[selma salem]

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.

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

[Diego Barragán]

very good

it didn't work by me. all commands would be described as unknown

[Shashank Tyagi]

gr8 it worked for me ...

[Sujeong You]

Good

[mes liste]

 

[mohammad amin abou harb]

extremely specific i mean you chose the 17th object in L==17 no intelligence as far as im concerned

[RC Choong]

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

[chenna rao]

good

??? The function, script, or class seg
cannot be indexed using {} or . indexing.

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

hi, I can not download it?!!!

[gourav kumar soni]

thank you ,, it helhs me.

[Saravanan]

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

[Chung-yeon Lee]

thanks for the simple code.
it's exactly what i wanted!

[Rushmi]

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

[kumar kumar]

how to give the value if i want to get all the text objects. if i give 17 i get only one , if i give any other i get only some dot.....

[Michael Jordan]

 

[bhuvaneswari]

i want to know how this program cuts a certain portion and also i want to know how to make this extract with true colour. pls give me solution soon

[Ashar]

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

[hendra togi]

hi sir..
I have a project in Digital Image Processing.
My project title is : Robust DWT-SVD Domain Image Watermarking.
I have a problem. after applying SVD to cover image and the visual watermark, I have no idea hoe to modify the singular values of the cover image in each subband with the singular values of the visual watermark
Thank you.
