For masking_code.py call save_masks with image names that you want to create a mask for:

PART 1

• in first pop up window click ‘p’ to enter polygon mode this will allow you to select a polygon by clicking various points

• when done selecting the polygon click ‘q’ which will fill in the mask on the image for you to see

• then click some point in the center that will be used to align the mask with the second image

• hit escape when done

• the state of the image can be reset by hitting ‘r’ note that you will need to hit ‘p’ again to enter polygon mode

• hit escape when done with the first image

• additional controls:

  • click ‘o’ or ‘i’ to rotate the image
  • click ‘=‘ or ‘-‘ to resize the image NOTE you must use the saved new source image for the mask to be applicable

PART 2:

• click anywhere in the image to overlay mask

• hit escape when done to save masks

• click r at anytime to reset frame

PART 3:

• masks are stored with the same name + “_mask.png” in the same folder as the code
• new source image is stored with name + “_newsource.png”

NOTE: May need to manually resize images so cv2.imshow can show whole image
