we use GUIDE to creat a GUI in which we load two images ,convert to binary images and calculates the percentage match.This is gud for studying image procssing for beginners.
i think this cud be modified better and hardware interfaced for clinical applications and person identification in places like an internet cafe.

Hi Anish, Nice one. Jus a question, on what metric is the tool making comparison ?

thanks a lot for the file image matching algorithm in matlab....
nice work

Hi Anish. Thanks for the reply.

Well I cannot understand how frequency domain can solve the problem. Can you please elaborate. Thank You.

thank u shirah.this is just a basic time domain approach program to understand image processing with a low size....and to perfectly solve your problem some frequency domain approach is needed..this can be understood by the the techniques elaborated in textbooks

Hello, interesting piece of work.

However, I have a query. What happen is that if the image is shifted by a few pixels, the message displayed is not matched and the matching percentage reduces considerably.

What according to you can be done in order to improve the situation?. I am thinking of integrating all the pixel values of the possible positions of an image into a matrix. What is your opinion?



nice work

nice info and code for beginner

What if the image is shifted a few pixels? Wouldn't that screw up the matching algorithm?


very nice program; hope it'll be helpful for my project.

In my project I want to measure the percentage (%) of waste in a solid waste bin by processing the bin image.

The picture will be taken by a fixed camera mounted with the collection vehicle. So the camera to bin distance is fixed if I can measure the top surface distance from the camera then I can calculate the % of waste.

Please help me how I can do this coding in matlab or any other programming.

i got some errors.. =(


i need a read me file

A read me file will certainly be appreciated

why if you compare the same 2 images but switch theyr input place (source with target) you get different percentage of match?

could you generate a readme file so that it becomes complete

looks very useful! can this be modified to compare differences in 2 shapes made out of points where the coordinates of each point is known?

or for simplicity changes on a chosen 2d plane? could be used to asses deformation in 3d shapes for engineering applications,
