Procedure for image segmentation of cotton seeds. a The original full image. b A binary image obtained by the Otsu threshold. c The area of image acquisition was extracted from the original image. d Each boundary of the image acquisition area was extended outward by 50-pixel points. e The cotton seeds near each other were connected, and the area of the cotton seed image was increased by an expansion operation. f All the contours were found by the contour finder function. g The cropped images
