Witryna10 The effect of the objective is that of a low-pass filter, with the cut-off frequency in 1D given by 2 2 M M Ob M kx f , (0.6) M is the maximum angle subtended by the entrance pupil from the specimen. Qualitatively, this low-pass filter has the effect of smoothing-down the details in the sample field, i.e. limiting the spatial resolution of the instrument. WitrynaThe rank filter sorts all pixels in a window of the given size, and returns the rank ’th value. Parameters: size – The kernel size, in pixels. rank – What pixel value to pick. Use 0 for a min filter, size * size / 2 for a median filter, size * size - 1 for a max filter, etc. class PIL.ImageFilter.MedianFilter(size=3) [source] #.
