Web21 de mar. de 2024 · Calculate the entropy of the image as the negative sum of the product of each element in the normalized histogram and its log-base-2. This can be done using the sum, element-wise array multiplication (.*), and log2 functions in MATLAB. For color images, you can calculate the energy and entropy of each color channel separately, and then … WebEntropy is a measure of the randomness or disorder of a system. The value of entropy depends on the mass of a system. It is denoted by the letter S and has units of joules per kelvin. …. According to the second law of thermodynamics, the entropy of a system can only decrease if the entropy of another system increases.
