WitrynaApplies a fixed-level threshold to each array element. The function applies fixed-level thresholding to a single-channel array. The function is typically used to get a bi-level (binary) image out of a grayscale image ("compare" could be also used for this purpose) or for removing a noise, that is, filtering out pixels with too small or too large values.
