.. vim: set fileencoding=utf-8 : .. Tiago de Freitas Pereira ===== VGG16 ===== The VGG-Face network model is made publicly available by the `Visual Geometry Group `_ at Oxford University. Involving almost 135 million trainable parameters, this network has been shown to achieve a FR accuracy of 98.95\% on the LFW unrestricted. VGG-Face is a CNN consisting of 16 hidden layers. The initial 13 hidden layers are convolution and pooling layers, and the last three layers are fully-connected ('fc6', 'fc7', and 'fc8'). The input to this network is an appropriately cropped color face-image of pre-specified dimensions. We use the representation produced by the 'fc7' layer of the VGG-Face CNN as a template for the input image. When enrolling a client, the template produced by the VGG-Face network for each enrollment-sample is recorded. For scoring, the network is used to generate a template for the probe face-image, which is then compared to the enrolled templates of the claimed identity using the Cosine-similarity measure.
