implement a few simple denoising and segmentation algorithms in PYTHON (computer Vision)

It has total 3 parts Part 1: denoising: in python implement your denoising method of choice 1) Bilateral filtering 2) Non-local means 3) Denoising autoencoder Part 2: segmentation: in python implement your segmentation method of choice 1) Otsu’s method 2) Watershed transform or region growing 3) Mean-shift clustering 4) Graph-cut 5) Neural network Part 3: practical challenge (vascular segmentation) Note: do not simply call opencv or scipy, or other python library. You must implement the algorithm yourself using primitive array operations in numpy. I will check your code line by line in the .py file you submit, to verify this* Rest I'll send everything in chat. Looking forward for good freelancer here. Thank you
