First of all this might be a little late, so sorry for that! I had uploaded this video exclusively for my friend due to time constraint. I have updated the links in description, both work fine! Just don't want to ask for coffee hence these links contain ads. Good Day!
very clear video.... Good to understand. But I didn't understand the process of Adaboost. i.e. how the weak classifiers are extracted by adaboost (i.e. how algorithm works mathematically in selection process of each weak classifier) What I mean to say is the process for detecting more than 50 matches. Thank you very much.....
Do you regularize the L1 norm using adaboost? Or does it assign zero weight to features that don't help when it iterates through that feature? Also, in the cascading portion, are the stages grouped by sorting the classifier weights? Thanks.
you will implement product of sum for each pixel in sub black window with corresponding pixel in original image and so on in the sub white window after that you will subtract results from each other
What if the face is bigger or smaller than the 24x24 window? In the real implementation of the algorithm, does it go through different sizes of window?
I think youre right! it took me a while to realize its not me who was wrong! i guess this amazing guy has done a mistake in the video! or i might be still not getting it! but anyway the tutorial is very well done.
no, because the numbers 1,2,3 and 4 describe only the locations of the areas ( inside of which the pixel-values are to be added) and NOT values per se. For example, the value of the integral image at location(!) 1 is the sum of the pixels in rectangle A, the value at location 2 is A+ B, etc...
plz answer a query that like snapchat is doing real time face detection and apply filters on it so this is also done with voila-jones face detection algorithm.
Sir, Can u give me the matlab code for edge detection of lines in the first slide? I am bit confused regarding the applying of haar features to the face. I mean I dint understand how the edges of horizontal lines are detected. Is it by convoluting the whole image with the kernel or substracting the image with the kernel. So if u could give me the code for this, I could understand it better
I am using imread command to read the image from computer in MATLAB but the error showing the image doesn't exist but it's in my computer Could someone help on this issue please

One of the best explanation, I have heard. Great work.
Thankyou for presenting this topic, I am glad algorithm(s)/techniques is presented very well and accurately.
Thanks a lot.... Very crisp and clear.... Great job!!! :)
Thanks to your video I took the best grade in my computer vision master degree exam! Thank you a lot

You are a legend
Thanks a lot. Please subscribe. I will be implementing Viola Jones Face Detection on Matlab and I will explain the code in the upcoming video.
yes waiting for matlab coding
when ur next video will be uploaded sir?

Thank you very much.....
if i nail my presentation about viola jones it'll be thanks to you man ! thank you very good explanations
Thank you. Great explanation of the algorithm.
what exactly integral image is and why it is used ? and what each pixel values represents as in 11:48
Thank you so much for the video. Very helpful in understanding viola jones. great explanation. :)
most welcome. If you need more help, don't hesitate to ask :)

Rahul thanks for your presentation, and good explanation
Thank you so much Sir, very well explained.
Thank you for the explanation!! Good job!!

Great explanation of AdaBoost and the Cascade, thanks!
AMAZING! Keep up the good work!

Very good presentation!
Which literature sources did you use?
Good Job,Very Helpfull :)
great explanation. I enjoyed it
What if the face is bigger or smaller than the 24x24 window? In the real implementation of the algorithm, does it go through different sizes of window?
Face-sizes larger than or smaller than 24x24 can be detected, 24x24 is not the maximum size. The classification can be repeated at different scales.
Thank you so much, clearly explained

In the example of the integral image shouldn't the value of c to be equal to 2? and after the calculations the value of d to be 1?

do you have any comparison between Viola jones algorithm and some other face detection algorithm. comparison analysis
I have a doubt, what we doing with the values obtained after subtracting the value at white region from black region in haar features?
plz answer a query that like snapchat is doing real time face detection and apply filters on it so this is also done with voila-jones face detection algorithm.
