Enhance Images, From 💩 to 🔥
Regarding the case of over-enhancement, I wrote another module that while enhancing contrast of the image, it keeps an eye on the histogram's general shape to prevent excessive enhancement. This method can be used for a more wide variety of images without any problem. You can access it here: imhblpce method.

Using numba, my code now runs faster by about 20 times 😲

Using numba my code runs faster by about 20 times 😲
I recently added im2dhisteq to my repository and because it was very slow, I searched for a new way to make my code run faster, as I was already using numpy built-in functions and there were no (at least easy) other way to optimize the code using just numpy. I recently found out about Numba, which is advertised to run my codes 1000 times faster, but as I later found out the degree of that is actually very dependant on your code. After reading through their website and through a long series of trials and erros I learned how to write a code that is Numba-friendly and is satisfyingly faster than my base code. website of Numba: Numba Proof: My code: https://github.com/Mamdasn/im2dhisteq In my repository, in addition to the Numba-flavord versions, I released the Numba-less versions, which are accessible here: im2dhisteq and imhist. You can check them out and compare them to come to a base understanding of how Numba-friendly codes looks like.
