You are a lifesaver. The paper itself was a bit above my level of knowledge of CV, but the way you explained really helped!

The sigma in the orientation assignment is incorrect. As stated in the paper "Each sample added to the histogram is weighted by its gradient magnitude and by a Gaussian-weighted circular window with aσthat is 1.5 times that of the scale of the keypoint." The value given in the slides corresponds to the sigma for the local image descriptor section

Thank you so much for pointing it out, I have trimmed that part for now and I will do the changes in the slides. Thanks again.

Your concepts are so clear, thank you so much this was amazing. I am working on a video stabilization project using lucas kanade algorithm and Im having some trouble with it.. Will it be okay to contact you about it ?

Can I use haris corner detector and SIFT for face?
@pratikian

So Sift in itself has the feature detection part so there is no need of using harris with sift, but if you want to use sift for a face you will have to do some changes. You can read some papers which have used the sift algorithm for face detection. For instance ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5234877

How to limit the number of descriptors for every image because i want fixed number of descriptors for 1000's of images ?
@pratikian

So what you can do is on every image detect a fix no. of harris corners and calculate the descriptors for only these harris corners

I have not made a code for stft. But i will try to explain there are these harris corners that you can detect. You can get the code from the description of this video kzitem.info/news/bejne/u5l705qok4KSm3o I have explained the code in the video . Or you can also use the inbuilt matlab command for harris. So what harris does is it detects corners which are known to be the best features. You can set the limit of how many corners you want to detect. Say for every image you detect 5 corners. After you do that you can directly use the sift feature descriptors only on these 5 corners. Like this you will get equal no. Of descriptors for every image
