    Hey Tim. After watching your several videos I noticed, that you struggle breathing while you talk. My girlfriend is a speech therapist and she said that going to this kind of specialist would make your life easier. You should consider implementing simple breathing exercises to prevent larynx disease. It's important, becouse you talk a lot.
    Thanks a lot for making courses and tutorials, they're great! :)

    Hi Tim! It's great that you continue this series. Please continue it, don't ditch it:)
    P.S: I'm studying CV at my uni and your tutorials are just gold!
    Please, continue them. You are amazing, I'm watching you since 2019.

    Just in case you're not a fan of the map function, try:
    color = [int(x) for x in np.random.randint(0, 255, size=3)]

    Don't stop making these videos, some of the best python tutorials on the whole of youtube!!!

    Instead of the map(lambda... for the np.random.randint you can also tuple a comprehension for the function.
    color = tuple(int(x) for x in np.random.randint())
    Great video, love your channel!

    If you get errors Corners = np.int0(corners)change np.int0 to np.int_(corners)

    I am a little confused with the line 19 at 19:59. Why did you use lambda x: int(x) instead of just a regular int(x). I don't use lambdas a lot so I'm wondering if I'm missing something here.

    • @TechWithTim
      @TechWithTim  3 ปีที่แล้ว +2

      Oh good point! I could have actually just passed “int” as the function

    on video cam, always set a fixed white-balance like 5500k. otherwise the color on captured image is changing with ambiant light.
    if you with greyscale, it doesn't matter

    • @tusharikajoshi8410
      @tusharikajoshi8410 3 ปีที่แล้ว

      it's for all the remaining corners. like, suppose i gives the 1st corner, so j will allow hold the value of all the other remaining corners, one by one, so that we can draw line from the 1st corner to every other corner.
      I am bad at explaining but I hope it helps.

  • @numo6144

    Hey Tim. I've known you and been following your tutorials for a while, now. I definitely appreciate your videos and content, don't get me wrong. I don't know why but I've noticed that (in your videos) that there is a sheer lack of expression and enthusiasm in your voice. I would suggest adding expression and enthusiasm in your voice in order to keep the viewers engaged.
    Best,
