Face Recognition, where that detected and processed face is compared to a database of known faces, to decide who that person is (shown here as red text). Since 2002, Face Detection can be performed fairly reliably such as with OpenCV’s Face Detector, working in roughly 90-95% of clear photos of a person looking forward at the camera.

Find and manipulate facial features in an image. Identify faces in images. Real-time face recognition. After detecting faces, the faces can also be recognized and the object/Person name can notified above .

In an image, most of the image region is non-face region. So it is a better idea to have a simple method to check if a window is not a face region. If it is not, discard it in a single shot. Don’t process it again. Instead focus on region where there can be a face. This way, we can find more time to check a possible face region.

Oct 13, 2018 · OpenFace is a Python and Torch implementation of face recognition with deep neural networks and is based on the CVPR 2015 paper FaceNet: A Unified Embedding for Face Recognition and Clustering by Florian Schroff, Dmitry Kalenichenko, and James Philbin at Google. Torch allows the network to be executed on a CPU or with CUDA.

Sep 18, 2019 · Expecting that this new approach would be useful to other vision applications, we tried to construct a probabilistic framework for face detection using the epitomic analysis, and then challenged to compare the performance with that of PCA analysis, which has been used to develop an efficient computational model for face recognition.
