Intel's OpenCV is a free and open-access image and videotape processing library. It's linked to computer vision, like point and object recognition and machine literacy. This paper give the main features, OpenCV modules and OpenCV grounded on Python. Apart from it gives common OpenCV classifiers and operations used in these operations like face recognition, image processing . Eventually, we bandy some erudite reviews of OpenCV operations in the fields of computer vision similar as face recognition, or recognition of facial expressions similar as sadness, wrathfulness, happiness, or recognition of the gender of a person.
