Comparison of using U-Net and Otsu thresholding on the original bread image, showing the overlapping of the pixel intensities histogram. (A) Input grayscale image, (B) ground truth image, (C) histogram of the ground truth of the pores and bread pixels, (D) Otsu threshold image overlaying on the grayscale input image, (E) intersection of segmented image using Otsu threshold and ground truth image, (F) histogram of the prediction of the pores and bread pixels using Otsu threshold, (G) U-net predicted image overlaying on the grayscale input image, (H) intersection of segmented image using U-net and ground truth image, and (I) histogram of the prediction of the pores and bread pixels using U-net.
