I'd like to thank you for making this video as it is a very helpful reference for my research!

[@SatyajitPattnaik]

Glad it was helpful!

How many times your model learned? I mean what is your epoch number on this project? Thank you

[@ujalamaurya292]

what accuracy you got for the model?

[@annisajaniarh6989]

Hi Satyajit Pattnaik, nice to see what u doing right now! i wanna ask you about the source at deteck_mask_video. what is prototxtPath = r"face_detector\deploy.prototxt" weightsPath = r"face_detector es10_300x300_ssd_iter_140000.caffemodel" where i get path prototxtPath and weightsPath ?

Hello everyone I am working on a project on this topic Not sure if the model you are making is the same as the model used in this video tutorial? I'm not sure if this videos is using MobileNet SSD V2 or MobileNetV2? Thank you.

Hi Sir. I have a doubt. Is Haar Cascade algorithm used in face recognition?

hi! is this using transfer learning?

At first thank you for making this project, brother now my question is,if i directly download the code from your github,and paste and run it in my Spyder console,will i get the output? I mean the video stream?

Yes, fork it.

Hey Satyajit, nice to meet you! I just found your channel and subscribed, love what you're doing! I like how clear and detailed your explanations are as well as the depth of knowledge you have surrounding the topic! Since I run a tech education channel as well, I love to see fellow Content Creators sharing, educating, and inspiring a large global audience. I wish you the best of luck on your KZbin Journey, can't wait to see you succeed! Your content really stands out and you've put so much thought into your videos! Cheers, happy holidays, and keep up the great work!

Sir can you pls say the questions that can be asked regarding this project for the interview?? i have got TCS interview tomorrow. pls help me

[@SatyajitPattnaik]

They would be asking your strategy for solving this problem, what all techniques are used, and they might deep dive into, object detection, CNN models, what are filters, how to define filters, input_size vs target_size, iterations vs epochs, back propagation etc etc.

Could you tell me how to improve the accuracy of face detection when it is far from the camera?

you need to add such images in the training data in order to have better accuracy

You can define the height & width like this: # Set the width and height of the window width = 800 height = 600 dim = (width, height) and just after you are capturing, pass the dim in the cv2.resize function # Capture the frame from the webcam ret, frame = cap.read() # Resize the frame resized = cv2.resize(frame, dim, interpolation=cv2.INTER_AREA)
