Hi - Great video and nice contrast to the TensorFlow one you have. Very clear, concise and to the point. Question - would you be able to recommend where I could get a similar overview of how to train / add / remove items into your model? Many Thanks again

[@TheCodingBug]

I am planning a video on adding new classes to the model or only perform object detection on selected classes.

[@cyberhard]

Excellent tutorial. You have a new subscriber.

[@padmavathynarasareddygari1213]

Hi- I have to say, a great video. It really helped me with my project. I made sure to recommend it to my friends. But I have a small doubt. Is opencv-contrib required to do it? Like can the project work without installing it? Thank you :)

[@TheCodingBug]

It was needed back then but I am not sure about now.

[@padmavathynarasareddygari1213]

@@TheCodingBug hmm, what do you mean now? Did OPENCV update or something 🤔?

[@TheCodingBug]

They add new methods and modules to opencv. Previously, DNN module was part of contrib. So had to install that as well.

[@padmavathynarasareddygari1213]

@@TheCodingBug okay. I'm unable to install contrib as it's getting stuck on building wheel, I'll try your code without installing it and I'll update what happens.

[@TheCodingBug]

Sure

[@opensourcethings]

heyy great video... but what if i want to add weapons in the object detection ... is there any method to modify your given model or let me know from where i can get this type of model which detect weapons also

Hello, I don't have videos in the "test_videos" folder. Where can I get the "street1" and "street2" videos?

why do i get this error SystemError: returned a result with an exception set

[@maulanamahmuddin5826]

Amazing content and really inspired me, permission to ask, is the difference between labelmap.pbtxt and coco.name the same or different? What I know is that a labelmap is a set of names that are used as json, if coco.name is just a list of names, right? If it's the same, can classesPath also use a labelmap? Please help and thank you

[@TheCodingBug]

Yes it's the same file with names.

Hi, is there a way to change vid source instead from recorded video, i want to direct it on my camera feed

[@TheCodingBug]

Use 0 instead of video path to use laptop or usb webcam

Thank you for reply, i will try that and give my feedback ty so much

How can I use Efficienet instead of SSD mobilenet. Will it work if I use pbtxt of SSD for efficientdet. I'm facing trouble finding pbtxt for Efficientdet. Can you please help me sir

No it'll not work. Efficient Det will work in TensorFlow. Check this video kzbin.info/www/bejne/aKq0opqVor2ohrM

[@pypoornith8516]

Hey, great video. Your script runs perfectly runs for me. But I wanted to change it up a little bit. Instead of showing it on the video using imshow(), it should print the name and confidence in the console. so I did something like this: displaytext = "{}:{:.2f}".format(classLabel, classConfidence*100) print(displaytext) but it is not printing the names of all the objects, its only printing the name of the first object it sees(I think). Can you please help me to modify this code so that it works the way I intended it to? Thanks again for the video 😀

[@reyamed720]

I trained a custom object detection model from a pretrained ssd_mobilenet_v2_fpnlite_320x320_coco17_tpu-8. I freezed it and after everything was done. I couldn't deploy it with openCV. I'm stuck now and I'd be grateful for any kind of help

Greetings from Azerbaijan! I've a very simple question but not meaningless. Can we add our own models to this method?

[@TheCodingBug]

Yes as long as it's compatible with OpenCv. You can use YOLO, Caffe and TF models.

I use yolov3 to detect 1 video but my computer's cpu is always running at 100% and the fps is very low, is there any way to fix it?

[@TheCodingBug]

YOLOv3 would never go beyond 2-3 FPS on CPU. Even with GPU, YOLO would give around 12-15 FPS (unless you use Darknet). You should use the model shared in this video if you plan to run object detection on CPU.

[@tungduong910]

[@TheCodingBug]

@@tungduong910 you have to build opencv with GPU support. I have made a tutorial about running YOLO with GPU support. You can find it on the channel.
