Computer Vision with OpenCV 3 and Qt5

Image thresholding

In computer vision science, thresholding is a method of image segmentation, which itself is the process of distinguishing between groups of related pixels, either in terms of intensity, color, or any other image properties. The OpenCV framework provides a number of functions to deal with image segmentation in general; however, in this section, you will learn about two of the most basic (although widely used) image segmentation methods in the OpenCV framework (and in computer vision): threshold and adaptiveThreshold. So, without wasting any more words, here they are:

• threshold: This function can be used to apply a fixed-level threshold to an image. Although it is possible to use this function with a multi-channel image, ...
