      It's color intensity values that range between 0 and 1.

    If I am not wrong. When you convert RGB image to Grayscale your dimensions should become 4928 X 3264 X 1 from 4928 X 3264 X 3. Right?. But i still see 4928 X 3264 X 3. Time - 10:12.

    • @bkrai
      @bkrai  7 років тому

      It will remain 4928 X 3264 X 3 as we have in the original file.

    Even when the path is set for the image file,an error message pops up stating that the path is wrong or the file does not exist.
    After numerous rechecks the error still persists.
    How ever really thank you for the tutorial and the code.

      Note that the way path is defined for Mac and Windows, there may be a difference.

      Mainly it says "No such file or directory". Make sure to provide correct path to your file. You can use getwd() to get working directory or setwd() to set working directory.
