Output of image segmentation for extracting grains and fitting the best ellipses. A A single image from the archive with more than 400 wheat grains. As an example, the grains in the white frame are processed in the next parts of the figure. B Output of resolution enhancement; C Result of image segmentation. A same thresholding is used for both resolutions; D Fitting the best ellipses to the single grains
