WitrynaThis non=changing filtered image is called the median root. It is possible using a special type of filter to reach this in one pass. If another order statistic is used instead of the median, such as the second prder statistic or third order statistic, then a few slight changes will occur relative ti if a pure median filter had been used. WitrynaDisplay the image array using matplotlib. Change the interpolation method and zoom to see the difference. Transform your image to greyscale; Increase the contrast of the image by changing its minimum and maximum values. Optional: use scipy.stats.scoreatpercentile (read the docstring!) to saturate 5% of the darkest pixels …
