How do you use an image as a dataset in Python?

Loading image data using PIL

  1. The source folder is the input parameter containing the images for different classes.
  2. Open the image file from the folder using PIL.
  3. Resize the image based on the input dimension required for the model.
  4. Convert the image to a Numpy array with float32 as the datatype.

How do I display a NumPy array of an image?

How does NumPy store images?

RGB images are usually stored as 3-dimensional arrays of 8-bit unsigned integers. That is because the data is ordered by lines, then each line is ordered by pixels, and finally, each pixel contains 3-byte values for RGB. Each colour is represented by an unsigned byte ( numpy type uint8 ).
