    Hey! You're saving my life, literally! I'm gonna have my first Image Processing's exam in two weeks, and I hadn't understood anything till I found your channel! You're a MVP! Now, I finally have an idea about what are all those concepts and formulas!
    Thanks a lot! I definitely subscribe!

    We know that we have +ve intensity values (0- 2^n-1). Right!
    In the output image, we have few negative values, so shall we round them off to 0 as we did in previous few lectures?

    there is a doubt, 450+300-400 = 150? it should be 350
    and also 150+500-400 = -150? it should be 250
    did you use some different method or is there any rule followed.
    Any one can solve this problem ?

    • @Harsh3901
      @Harsh3901 9 дней назад

      actually bro there was a calculation mistake as 50x5 = 250 not 450. so it is 250+300-400 = 150

    Your efforts are tremendous!
    My suggestion to you start the series of episodes with practical knowledge,
    Start with analog image, and end with analog image (degital copy of analog image)
    Not only students but anyone wants to know about this can easily understand!
    I mean to say, image, camera sensor, ADC, memory, print etc must be involved.

  • @govindgupta6676
    @govindgupta6676 Год назад +1

    In Ques. 2; We'll get output as -20 if apply the enhaced filter with -5 as center but with other mask, the answer is -24 as shown by you. Then which one is correct ??

    Mistake at 16:24 and 17:21. Thus the result image is wrong.

    • @collegefriendly
      @collegefriendly  3 года назад +3

      Thank you so much for pointing this out. The values would be 350 and 250 and therefore the final image would differ accordingly. I hope that you understood the concept though :)

    • @atikhasan4358
      @atikhasan4358 3 года назад +3

      @College Friendly Thank you for detailed explanation. But sharpen_image = original_image - filtered_image. Here, you only determined the filtered_image, not the sharpen image. This actually made some confusion. Keep posting.

    • @pritamdas4441
      @pritamdas4441 3 года назад

    In Q.3 there is a small calculation mistake . When shifting the mask 3rd time ( 50 * 5 +100 * 3 - 50 * 8 )
    = 250 + 300 - 400
    =150
    instead of 250 by mistake you have written 450.
