And pleaase, could someone explain me the meaning of each constant:

MIN_PIXEL_WIDTH = 2 MIN_PIXEL_HEIGHT = 8 MIN_ASPECT_RATIO = 0.25 MAX_ASPECT_RATIO = 1.0 MIN_PIXEL_AREA = 80 MIN_DIAG_SIZE_MULTIPLE_AWAY = 0.3 MAX_DIAG_SIZE_MULTIPLE_AWAY = 5.0 MAX_CHANGE_IN_AREA = 0.5 MAX_CHANGE_IN_WIDTH = 0.8 MAX_CHANGE_IN_HEIGHT = 0.2 MAX_ANGLE_BETWEEN_CHARS = 12.0 MIN_NUMBER_OF_MATCHING_CHARS = 3 RESIZED_CHAR_IMAGE_WIDTH = 20 RESIZED_CHAR_IMAGE_HEIGHT = 30 MIN_CONTOUR_AREA = 100

Hey -

  1. So I don’t think the dataset for the character recognition includes Arabic chars. You will have to find a new dataset that includes those and train the model on that
  2. Those Params are used to control the code that finds characters on the license plate. They set the min/ max size, aspect ratio, etc. you will have to walk though the code to understand how each is used. On Mon, Sep 24, 2018 at 8:21 AM A_HM notifications@github.com wrote:
