Fisherface opencv

WebFacial recognition is a major challenge in the field of computer vision. Here we have implemented various facial recognition algorithms like LBPH, Eigenface and Fisherface. Haar cascade has been used for facial identification. We trained the algorithms using the same data set and have got some insights, from which we have tried to identify which … WebMar 13, 2024 · haarcascade_frontalface_alt2. 时间：2024-03-13 20:40:00 浏览：2. haarcascade_frontalface_alt2是一种用于人脸检测的级联分类器，它是基于Haar特征的算法实现的。. 它可以识别正面的人脸，并且在一定程度上可以适应不同的光照和角度。. 这种算法被广泛应用于人脸识别、人脸 ...
