WebB. Local thresholding Local thresholding states that if the value of threshold T depends on the grey level value and local properties of the image pixel the that is known as local thresholding technique. In this approach of thresholding the various thresholds are opted from the various respective segmented regions of the image [3]. WebThresholds each element of the input Tensor. Threshold is defined as: y = \begin {cases} x, &\text { if } x > \text {threshold} \\ \text {value}, &\text { otherwise } \end {cases} y = {x, value, if x > threshold otherwise.

"In computer vision and image processing, Otsu's method, named after Nobuyuki Otsu (大津展之, Ōtsu Nobuyuki), is used to perform automatic image thresholding. In the simplest form, the algorithm returns a single intensity threshold that separate pixels into two classes, foreground and background. This threshold is determined by minimizing intra-class intensity variance, or eq… " - Otsu multi thresholding
