Side window median filter
WebMar 21, 2024 · [2,3], the median is (2 + 3) / 2 = 2.5. Given an array nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position. Your job is to output the median array for each window in the original array. WebA value of 0 (the default) centers the filter over the pixel, with positive values shifting the filter to the left, and negative ones to the right. By passing a sequence of origins with length equal to the number of dimensions of the input array, different shifts can be specified along each axis. Returns: median_filter ndarray. Filtered array.

WebMedian Filter. A statistically robust alternative to the moving-average filter is the median filter. Where a moving average filter takes the arithmetic mean of the input over a moving sample window, a median filter (per the name) takes a median instead.
