WebIn this paper, we propose a novel bi-level histogram thresholding technique based on the beam the- ory of solid mechanics and information ambiguity minimization. We demonstrate its application in segmentation and edge detection for grayscale and color images. The proposed method is suitable for thresholding both unimodal and multi-modal histograms.
