In the second case, Otsu's thresholding is applied directly. In the … Webb16 jan. 2024 · If the threshold T is constant in processing over the entire image region, it is said to be global thresholding. If T varies over the image region, we say it is variable thresholding. Multiple-thresholding classifies the image into three regions – like two distinct objects on a background. how much jail time for hosting car shows

WebbMany image processing programs allow Dilation and Erosion of edges of characters against a common background to dilate or grow in size (Dilation) or shrink (Erosion). Heavy ink bleeding from historical documents can be compensated for by using an Erosion technique. Erosion can be used to shrink characters back to their normal glyph structure.
