Image filtering: denoising, sharpening Image segmentation: labeling pixels corresponding to. Image manipulation and processing using Numpy and Scipy. (or 3-D: CT, MRI, 2D time 4-D,.) Here, image Numpy array ray. We can also use 2D boolean masks for a 2D color image, as we did with the. Array operations for data munging and cleaning, subsetting and filtering.
