The red color, in OpenCV, has the hue values approximately in the range of 0 to 10 and 160 to 180. Then, we will iterate through all of the faces detected and extract their start and end points. It is possible to add a wait_for_key during the object detection phase and as soon as a rectangle is identified manually specify if it’s text or not. Distinct but not Mutually Exclusive Processes The process of object detection can notice that something (a subset of pixels that we refer to as an “object”) is even there, object recognition techniques can be used to know what that something is (to label an object as a specific thing such as bird) and object tracking can enable us to follow the path of a particular object.
