Figure 7From: Segmentation of epidermal tissue with histopathological damage in images of haematoxylin and eosin stained human skin Histogram of enhanced additive image showing Otsu threshold. Figure 7 shows the intensity histogram of image pre-thresholding. The image has been created by combining a contrast enhanced b* image plane and a contrast enhanced grayscale image. The optimal threshold calculated using Otsu’s method is labelled on the histogram.Back to article page
