WitrynaThe more diversity is in the image, the higher the computed value would be - this should give a rough estimate of the homogeneity / uniformity of the image. Sorry for the late edit, I want a metric which would be independent of the Scale. Should probably also divide by the number of pixels. @AyushPandey that would solve scaling.

Witryna19 sty 2024 · 2. The answer to your question depends on what you are attempting to do. If X represents the data associated to a greyscale image, then the entropy function is what you are looking for: X = [1 2 2 0]; H = entropy (X); % 0.811278124459133. But neither your X variable, nor your expected result ( 1.5) point to that solution.

WitrynaOperator precedence could take care some of these issues. If \sin x + y was the input, then left-to-right precedence could dictate the output to be sin (x) + y. And to obtain sin (x+y), we would have to code in LaTeX \sin {x+y} or \sin (x+y). Implied multiplication is indeed very common in mathematics and latex.
