Web22 de abr. de 2015 · The minThreshold sets pixels bellow that value to zero. The maxThreshold sets pixels above that value to zero. Imagine your minThreshold = 10 and maxThreshold = 200. In your grayscale image the pixels with value bellow 10 will be set to zero, and pixels with value above 200 will also be set to zero. WebThresholding is a method of image segmentation, in general it is used to create binary images. Thresholding is of two types namely, simple thresholding and adaptive thresholding. Simple Thresholding In simple thresholding operation the pixels whose values are greater than the specified threshold value, are assigned with a standard value.
WebThe function applies fixed-level thresholding to a multiple-channel array. The function is typically used to get a bi-level (binary) image out of a grayscale image ( cv.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.
