"A New Method for Grey-Level Picture Thresholding Using the Entropy of the Histogram,"" Signal Processing 2, no. 3 (1980): 223–237. Global thresholding (Multi-threshold) WebOct 18, 2024 · Global thresholding determines the threshold value based on the histogram of the overall pixel intensity distribution of the image. In contrast, adaptive thresholding computes the threshold value for each fractional region of the image, so that each fractional region has a different threshold value.
