Training a better Haar and LBP cascade based Eye Detector ...Jan 23, 2017· Object detection using Haar feature-based cascade classifiers is more than a decade and a half old. OpenCV framework provides a pre-built Haar and LBP based cascade classifiers for face and eye detection which are of reasonably good quality. However, I had never measured the accuracy of these face and eye detectors.Linear Asymmetric Classifier for cascade detectors ...Cascade classifiers provide an efficient computational solution, by leveraging the asymmetry in the distribution of faces vs. non-faces. Training a cascade classifier in turn requires a solution for the following subproblems: Design a classifier for each node in the cascade with very high detection rate but only moderate false positive rate.Face and Eye Detection using OpenCV and Python (cv2)Aug 19, 2019· There are two stages in a cascade classifier; detection and training. In this tutorial, we will focus on detection and OpenCV offers pre-trained classifiers such as eyes, face, and smile. In order to detect, those classifiers, there are XML files associated to the classifiers that must be imported into your code.
