WebbEntropy was introduced by Shanon (1948), were the higher value of Entropy = more detailed information. Entropy is a measure of image information content, which is interpreted as the average uncertainty of information source. In Image, Entropy is defined as corresponding states of intensity level which individual pixels can adapt.

WebbCalculate the Shannon entropy/relative entropy of given distribution (s). If only probabilities pk are given, the Shannon entropy is calculated as H = -sum (pk * log (pk)). If qk is not None, then compute the relative entropy D = sum (pk * log (pk / qk)). This quantity is also known as the Kullback-Leibler divergence.

Webb11 apr. 2024 · To make membership degrees of each image pixel closer to those of its neighbors, a KL divergence term on the partition matrix is introduced as a part of FCM, thus resulting in KL divergence-based FCM. To make the proposed FCM robust, a filtered term is augmented in its objective function, where MR is used for image filtering. WebbShannon’s entropy metric helps identify that amount of storage needed for the information. One alternative way of looking at entropy is thus as a measure of “compressibility” of the …
