Face detection accuracy
WebMar 18, 2013 · 2 I have recently started learning opencv and written a program to detect faces in an image in python and save all detected faces as separate images. It works fine for some images but fails to detect all the faces in many images. It fails in even this ( http://imgur.com/HUh3tIK) simple image. It detects only the right face but not the left face. WebNov 1, 2024 · In the current work two algorithmsare used to detect the faces in the image containing many faces to calculate the accuracy then the acquired accuracy will becompared by plotting the curve and bar graph to find the efficient algorithm. There are two types of image positive image and negative image.
