Күн бұрын

Learn everything you need to know about OpenCV in this full course for beginners. You will learn the very basics (reading images and videos, image transformations) to more advanced concepts (color spaces, edge detection). Towards the end, you'll have hands-on experience building a Deep Computer Vision model to classify between the characters in the popular TV series "The Simpsons".

2:08:26 - actually everything was OK. You don't need to pass masked image to calcHist mask parameter. You can just pass white circle instead, as you did first time. You can compare both histogram plots and make sure, they are identical. It worked because cats-in-a-circle image is identical to white circle in bitwise operations (if those cats have no zero valued pixels in the circle region)

Hey I see your effort. You all are putting so much effort and time in these videos. I think if you make the roadmaps videos like if you want to become a android developer watch this playlist in which you can mention all the videos that are related to the android development. Yes I know that you already had created playlists but they are kinda incomplete and are not roadmaps videos. And one more suggestion make a playlist of roadmaps videos for different learning paths like you had created pytorch and tensorflow tutorials if they both are mentioned in a roadmap video of data scientist and a pdf in description as if anyonnes wants to print and want the learning steps so he/she can download the pdf. I hope you will like my suggestion. Even I follows your tutorials but i didn't know whether the tutorial is for my path or not and then after researching and learning my own I find that you had made the tutorials but I was not able to identify that the tutorial is helpful or not. So if you do this it will save so much time and everyone will know what to do next. Thanks For Reading My Suggestion :)

The tutorial is great. Everything is explained in a great way. The only thing that I felt could be improved is by using some constants instead of just writing them again and again like you did in draw.py. You could've specified constant like STARTING_POINT, ENDING_POINT, COLOR and many more which would've made the code much more readable and could've also reduced the tutorial length. I would be making a pull request for this soon. Thank you for this amazing tutorial :)

All you had to do is use "from cv2 import cv2 as cv" rather than "import cv2 as cv", this fixed the issue for me, try it once.

Thank you so much! One question: Do I need to "normalise" the input image before send it into model.prediction in the Simpsons demo?

@jasmcaus 2 жыл бұрын

Depends what you mean by normalise. To train effectively, your input images will need to be structurally similar - this means that if one input image is 640x320, *all* the other images must be 640x320. If you expose one image to mean subtraction, it would be wise to do the same for the rest of the images. Hope this helps! Cheers :)

Hey, got an error when creating the image training generator on line: train_gen = datagen.flow(x_train, y_train, batch_size=BATCH_SIZE) Not sure why it gave the error below ValueError: `x` (images tensor) and `y` (labels) should have the same length. Found: x.shape = (80, 80, 1), y.shape = (11047, 10, 10)

Okay, here's the shortcut I found about VS Code: Ctrl + '/' -> Comments out a line Alt + Up/Down Arrow -> To move text up and down And this is personalized: Alt + D -> Duplicates the lines Please share your shortcuts as well.

In Face Recognition section, at 3:07:45 , in my case, model is always recognizing image with confidence of 0.0 . Could anyone please help me? Please?

@56_ashishsingh91 3 жыл бұрын

How many images are you using to train your model?? If you use more images then confidence would also increase.

@egemeyvecioglu3165 2 жыл бұрын

Same problem, but i assume the confidence is actually 100.0 and there is a problem due to data type because i always get the correct result.

When i try to import cv2 it says that it cant import it, And I installed it, (I checked twice) That is what the compiler says: "ImportError: numpy.core.multiarray failed to import" Someone knows why?

check your numpy version: print(np.__version__) I've had issues with 1.19.4. Then downgrade to 1.19.3 in the terminal using: pip install numpy==1.19.3

If you are using VScode try from cv2 import cv2 instead of import cv2 as cv this worked for me
