Obviously if it's not only the filename, but also the image inside that file that is different, then all bets are off. WitrynaBW = imbinarize (I) creates a binary image from 2-D or 3-D grayscale image I by replacing all values above a globally determined threshold with 1 s and setting all other values to 0 s. By default, imbinarize uses Otsu's method, which chooses the threshold value to minimize the intraclass variance of the thresholded black and white pixels [1 ... simply planning cardiffWitrynaValues equal to either threshold is considered to be between the thresholds.

"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.
