Getting ready
Consider the following:
- A lot of algorithms are devised to crop the significant part of an image; for example, SIFT, LBP, Haar-cascade filter, and so on.
- We will, however, tackle this problem with a very simplistic naïve code to crop the facial portion from the image. This is one of the novelties of this algorithm.
- We have found that the pixel intensity of the unnecessary background part is 28.
- Remember that each image is a three-channel matrix of 200 x 200-pixels. This means that every image contains three matrices or Tensors of red, green, and blue pixels with an intensity ranging from 0 to 255.
- Therefore, we will discard any row or column of the images that contain only 28s as the pixel intensities.
- We will also make sure ...
