Tutorial 74 - What are Gabor filters and how to use them to generate features for machine learning?

For image processing and computer vision, Gabor filters are generally used in texture analysis, edge detection, feature extraction, etc. Gabor filters are special classes of bandpass filters, i.e., they allow a certain ‘band’ of frequencies and reject the others.

Okay, so recently I started searching about image processing trying to make some sense of sparse models in the primary visual cortex. This is one of the most amazing videos I've watched so far, you respect the viewer's time and there are a lot of people that appreciate, I for one, love it when someone is to the point and with visual examples. I sincerely thank you for your content, and looking forward to checking all your other videos. Stay amazing, you're doing something noble in my opinion.

thanks! working on my thesis. you got yourself a subscriber! simple, to the point, well explained

i wish you were my teacher i would have been a scientist today really loved the way you make things not just theory but something which is learned to be applied

[deepeshmehta]

Your content is just awesome!!
Gr8 explanation! Covering math, code and theory all in one complete package.

Thanks for explaining this concept in easiest way. Thanks a lot.

Really good tutorials, explained very nicely. I am definitely interested in learning more about the machine learning aspect of this. I am an electronic engineer for 10yrs but new to ML I was planning to do a project where some image processing and possibly machine learning would be used to improve results. It seems like this might suit. I had heard about a Joint bilateral filter that removes noise but preserves edges. Lot of research to do still!

Thank you very much!!! You really helped me understand this. Thanks for great tutorial!!

This was amazing! Very well explained! Thank you!

Thank you Sreeni, yes I am very excited about Gabor filter and waiting for the next video :)

I was looking into how fingerprint scanners work today, and found many articles saying that the scanners use gabor filter for better image. Spent like the whole day looking what a gabor filter is... Was initially hoping for some program with UI... nope. Tried to run the python code. Didnt work either. So i ended up downloading some matlab app for applying gabor filter.
A question arose after i did that, if the fingerprint scanners do actually use the gabor filter, do they apply it to small portions of the fingerprint at different angles, and then combine the whole image piece by piece ?

Hello hope you doing well. I am working on one project image classification through vision Transformer. I have question related Gabor Filter. when we apply 3D Gabor filter on image is there any gabor weights like(Gaussion Initialization weights) Generate or Not? If it is weights generate so how we can use this weights? Mean to say I want to use 3D Gabor filter weights to initialize hidden layer not with Gaussion initialize weights. Thanks

Where is the video that goes over gabor filter selection?

[sohailali]

Thanks for great tutorial. I have road surface image in which I want to detect crack, but color of crack and pavement is almost similar and hard to distinguish. Can you please please let me know that will gabor filter help to enhance image? Particularly, can it help to differentiate crack and normal pavement?

Your response will be highly appreciate.

Thank you.

Amazing, thank you so much
Could please advise which mathematics course good for machinelearninig?

[ahmadirtisam]

Can we detect any Object using this Algorithm ?
