No one on you tube do this project for biggener level
, but you did in perfect manner Sir
Thank you So much Sir.
TNice tutorials is exactly what I needed to understand the UI. Great tutorial!
The best explained video for object detection I've encountered so far!! Keep it up Bro
Thank you very much sir, this was just the perfect introduction t actually implementing computer vision!
This is the most selfless video for object detection have every seen! the steps by steps provided clearly and most important WORKING! it is really helpful for a beginner like me. Thanks author!! You save my life!
Hi it's only detecting person even if it is a car in VideoCapture .it's all good in img detection but the only problem is video object detection. could you please share your code if you've done it
bro, can u give the graph of deep learning architecture? u did not provide that link
You explained it very well. You made my day . I am so happy that I had learnt something new.
Have just finished this. Thanks very much for making it. Have liked and subscribed!
Thank you for the expertly presented tutorial and demonstration.
the best video so far and help me a lot. thank you.
Thank you so much for your effort. Really helpful 👍🏽🙏🏼🙌🏽
great job, Could you please teach me how a new dataset is labelled and implementation of all the approaches of object detection. As I am new to this area. I liked the way you described.
Fixed the problem with the bounding boxes:
Replace “img” with “frame” in:
cv2.rectangle(img,boxes,(255, 0, 0), 2)
cv2.putText(img,classLabels[ClassInd-1] ......., thickness=1)
Now it should work and display bounding boxes in the video!
Great video! Very helpful!
Hey, im getting 'name cv2 is not defined' . How to correct the error
@@BruceWayne-xq7bb if you are getting error like module not found try to check if opencv is installed or not then just try this in cmd (pip install opencv-python)
@@kanawadeatharva7705 hey bro you got the code in this video?
@@mohammedazzan7529 yeah!!!
I need to put together a script that copies images containing only certain objects. I tried looking for tutorials, but all of them are hellbent on teaching people how to train AI to tell apart dogs and fish. All I needed was to be spoonfed on how to use a pre-made model.
Thank you so much.
Hi, sir I really appreciate your detailed explanation and it's very easy to understand, there is a mismatch in labels and the pre-trained model. It took me some time but while classifying the images the model predicts the label 'fire hydrant' at position 11 and 'stop sign' at position 13, whereas in the labels list the 'stop sign' comes just after the 'fire hydrant'.
How can we solve this problem?
Simple. And clear tuto thank you so much
Amazing tutorial.Thanks Mate
Really that details hits different
So informative, thanks a lot!
YOU SAVED ME ALOT ON MY FINAL YEAR PROJECT
Hi ma'am.i also stuck in last stage. Attribute error :tuple not have attributes flatten. Plz help .its also my final year project
hello can you send me the code please?
Thanks for teaching such complicated concept in simple words. Kindly guide me if we can integrate hardware like LED etc to such projects after detecting a specific object in real time.
Amazing video. Great job
Thank you so much sir from the bottom of my heart 💖.......it helped me a lot in my project
Can you please teach how to features analysis using deep learning techniques? Your videos are very helpful to us. Thank you :)
Thank you so much for this tutorial, it helped me a lot, I have a doubt, how do we know the values to set up the configuration
thanku for the wonderful explaination
thank you sir it very helpful for me
Thank you so much.well explained.
hi willing to help me with my code? I seem to get a different resolution of my video than the original...
It's really helpful
KEEP IT UP
Great video
Nice work bro
Thank you so much, explained everything very well........... i have worked on my own video and its working very nicely.
how do i calculate the accuracy of prediction of our object detection.
i have also calculated the confidence............by which it shows like for "person "-70%....if i want to do more analysis then what can i do and how to do that
Can u share the link of the frozen model
@@pudinanno bro can u shar link of the frozen model
Nice video man ,I liked it
quick question, what if the frame and classes doesnt show in my video/webcam? is there anything that i can do to fix that?
what a absolute legend!
@@refrefwgwgwegew cap.set(3, width) and cap.set(4, height) whereas width and height is your preferred resolution
@@refrefwgwgwegew No. cap.set(3, width) where width is a number and cap.set(4, height) where height is a number. Try cap.set(3, 512) and cap.set(4, 384)
very informative video and i learnt very much from this , if you could post more tutorials about deep learning and explainations will be helpful.
hi could you tell like what changes i need to make if i want to add new class files such as chair , pen , phones etc . for the real time web cam detection?
thank you so much! this was a really great learning experience!!
given it's now 2022, would you suggest a different model that we should use? is this one outdated? or still the same one is good?
help full👍👍
perfect.
Excellent...!
Thanku sir.. ✌️❤🤗😇
my friend it was a very good video👌😀
thank u sir for this tutorial
This is a great video i love it,
but i have a question,
can you teach me how to count how many person or car in the video? like i need a counters for data also
SIr I am working on a project which is to detect cotton using OPENCV Res Pi, Sir as the cotton data set is not available, is it possible to use a google image of any cotton to detect our cotton ball using HSV? Please reply.
Nice video, Everything is very clear. Only one doubt, how can we export the frozen inference graph? It would be better if you share the link for the frozen inference graph file. Thanks
Same doubt.. Graphs were not there??
Good job
Sir i cant find that particular stock footage that you used ,can you link it here.
Helpful
Nyc geeat
Gud job
That's a nice video, but how can I do the same using cv2 but for custom dataset? Change the num of classes and make the model detect the ones I've set?
I don't find the frozen_inference_graph.pd here in the link after downloading,would you please share
Thank you sir!!!
Hi...
Thank you for the tutorial.. It's impressive. I have one question.
Can we make the animation of moving objects a function of time? the program will run and continuous animation will run???
Thank you
@@heribertojuarez6046 Yes.. I make the animation of moving objects... Thank you very much..
so helpful video
Sir can you please tell us if we want to increase that Labels dataset i.e want to include more things than how we will do that
bhai thanks yaar !!!
Hi sir, 1) my real time video doesn't capture the whole video. Any ideas on how to get the whole video with detection instead of a screen where the video is only partially visible. 2) the video window doesnt disappear when I stop the jupyter program. I hope you can give us an update. Amazing video!
Sir in this project how we can add abnormalities part like if two persons are fighting or person is holding nife ,or we can say road accident then how we can show that
Thank you Teacher
Thanks bro it work 👍🏻, (auto subscribe)
So good
Thank you sir
Hello Sir, first of all you did a very nice job with easy explanation! Now I found some errors while detecting objects in real-time mode. For instance, phone is detected as a sink, scissors and the chair as a toilet or some kind of staffs. So how can I improve the accuracy of object detection in real time mode? In my case, it is perfectly detecting the person only.
Thank you in advance :)
me too same Pb
feed the model with more data
awesome
I like your video.......
Great
can you please share the whole code which you just implemented on screen using JN? I will be glad.
Thanks a lot man !!!
where can i get information abt mobilenetv3 pls guide
For importing a video, I keep getting an error seen below.
error: OpenCV(4.7.0) /Users/xperience/GHA-OCV-Python/_work/opencv-python/opencv-python/opencv/modules/imgproc/src/resize.cpp:4062: error: (-215:Assertion failed) !ssize.empty() in function 'resize'
I am not really sure how to fix it and I was hoping somebody might have some insight for me.
Thank you for the video! It was really helpful, but can you send us a link to the code? I'm looking forward to more of your videos!
Thank you ☺️
the final video with all the boxes and names does not open up
that is after typing the last code and pressing shift enter nothing happens.
please help!!
cv2.imshow('Object Detection Tutorial',frame) I got an error here. Does the quote name should be unique?
you have to run the whole code with the config files
sir can u help i have a reserch 1 then object detection is my study. but i dont have idea to do a object detection
thanks for a great video I learned a lot.
I would love for such great videos always.
just wanted to ask , if you can paste a link to the model (frozen inference graph) for some reason is not in the zip file.
You can delete the question I found it
i just un-tar the file
ssd_mobilenet_v3_large_coco_2020_01_14.tar.gz
you saved me
@@zafrirhavia2795 how could you un tar the file please explain mee
@@megamega3642 bro you got the code for this video?
Nice
Is it possible to run this on a GPU to speed things up. Thanks. I hope you get your PhD.
Well
hello sir mind if i ask on how can i have audio speech whenever an object is detected how may i implement it…
nice, thanks!
Please ..
Can anyone provide documentation for this project like diagrams, project estimate and quality assurance
Wow
Hi, If I want to detect some other object outdide this 80 classes how can I do that please answer me
NYC
Good
Hello, anyone can help me to fix this error (it shows only when i changue the image)...
'tuple' object has no attribute 'flatten'
can u give the graph of deep learning architecture? u did not provide that link
Hello sir, thank you so much for this informative video, I was running the same code on my laptop, with all dependencies installed, in the last code segment I’m getting the error
cv2.imshow(“Object Detection Tutorial”,frame)
Invalid syntax
I have rechecked the code multiple times and have also run the above code . Could you please help me with the solution
Same, I am doing it in colab. Did you find the solution?
sir where can i find frozen interference graph pb
Hi please advise what software packages kneed to me installed before beginning this tutorial?
I keep getting a cv2 error when executing any commands
you need to download python , pylab, and matplotlib
@@adityatiwari2325 downloaded it, not getting another error
thank you! your explained is so amazing really.. but i want ask you about how if i want generate a custom model, to detect something i label ? can you do a tutorial? your way of explained is so understood
Sir, webcam is not displaying the names please reply sir
👍👍👍
Thanks for sharing your time and knowledge!
Do you have any idea what could be causing this error?
me too
