Hello Bhavik,
 Are you talking about what to do after step 6?
Note that, the tutorial site is all about the implementaton of the SIFT algorithm.
As I said earlier, SIFT is the main keypoint generator for my algorithm. Without having a properly working SIFT, you can't match any images.
Please investigate the documentation(the program comments, explanatory algorithm images) of my code(which I believe it is pretty good documented) if you would like to implement a variant of my algorithm.

Hello Milind,
 Thanks for your compliments.
It is so nice to hear from you again.
It is also so great to hear about your progress.
I really wondered what kind of modifications you did to the algorithm.
Also note that, I was planning to publish this algorithm as a conference paper. I would appreciate if you can contribute and share your findings. So that you can be one a co-author for this algorithm.
If you are interested send me a private message.
I am waiting for your reply.
Best,

Hello Kok Hong again,
 I would suggest you to investigate the match function.
%[match1,match2,cx1,cy1,cx2,cy2,num] = match(image1, image2, distRatio)

The returning value "num" keeps the matched number of keypoints.
"num" would resolve this issue.
If it doesn't please inform me. So that I can correct it in the next revision.

Hello Bhavik,
 Nice to hear from you again.
It is also unclear to me about the .pgm related implementation.
This .exe is downloaded from http://www.cs.ubc.ca/~lowe/keypoints/ .
For your SIFT related questions, I would definitely recommend the following site:
http://www.aishack.in/2010/05/sift-scale-invariant-feature-transform/
I hope everything is going well for you.
Take care,

hello Kok Hong,
 As far as I can remember, the pgm file is a process file generated by SIFT. Since the SIFT function is called outside MATLAB, you can't have appropriate updates onto core SIFT function unless you change it with a MATLAB implementation.

Hi Caglar,

we are following the same blog:
http://www.aishack.in/2010/05/sift-scale-invariant-feature-transform/

for tutorial and algorithm flow. We are writing the code in MATLAB using it's Image processing toolbox functions.

we are reached till step 5 for assigning orientation fr pixels around the keypoints to all the database images. We are stuck up in next step, as in what to do after tat ? and how to compare the database images with the input images. Please help us understand the last step.

or can you please mail any documents if you have on gandhibhavik.89@gmail.com

Thanks

Hey Caglar, you are welcome. It's nice to see you helping out others here.
Last summer when I commented on this thread I had actually made some changes with some of your algorithms and managed to increase the pattern matching efficiency to more than 95%.
If you would like then I would like to post the same here. Also I changed the method of input for the images; as in you can have different methods for inputs.
