Three-dimensional distortion-tolerant object recognition using photon-counting integral imaging
Optics Express, 2007 This paper addresses three-dimensional distortion-tolerant object recognition using photon-counting integral imaging (II). A photon-counting linear discriminant analysis (LDA) is proposed for classification photonlimited images. In the photon-counting LDA, classical irradiance images are used to train the classifier.
