WitrynaImage segmentation is highly useful in defining objects and their boundaries. In this chapter we perform some basic thresholding operations on images. We use OpenCV function threshold. It can be found under Imgproc package. Its syntax is given below − Imgproc.threshold (source, destination, thresh , maxval , type); 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 …
