Robust local binary pattern. Face recognition is an easy task for humans. , Eigen values, Fishers and Local Binary patterns Histogram. For now I'm using just raw vector of pixels, I tried to convert it with Local Binary Patterns but it still gives bad results, I think I need to compute histograms based on LBP, but not sure how. However, convolution is much older than morphology, and it generates more grey-scale gradient effects, rather than the binary shape studying effects that morphology typically generates. In our dataset, you will see different people. The features are calculated similarly to local binary patterns (LBPs), except that summed blocks are used instead of individual pixel values. I have helped to develop new techniques for static and moving shape extraction (both parametric and non-parametric) which have found application in automatic face and automatic gait recognition and in medical image analysis.

The first two methods require a set of samples with same resolution and even the predicted image should be of same resolution. The rest of the variables are local variables of a pattern body. Conventional local image descriptors often only employ the rectangular gradient information of detected region around each interest point. The local directional derivations are then utilized to encode the binary patterns in the given orientations. For the Eigenfaces and Fisherfaces method, this is algorithmically not possible and you have to re-estimate the model with FaceRecognizer::train.
