Abstract
A face detection device based on a convolutional neural network is provided. The device includes a feature extractor assembly and a detector assembly. The feature extractor assembly includes a first feature extractor, a second feature extractor and a third feature extractor. The first feature extractor is used to apply a first set of convolution kernels on an input grayscale image thereby generate a set of basic feature maps. The second feature extractor is used to apply a second set of convolution kernels on the set of basic feature maps and thereby generate more than one set of intermediate feature maps, which are concatenated. The third feature extractor is used to perform at least one convolution operation on a concatenated layer. The detector assembly includes at least one detector whose input is derived from one of the second feature extractor and the third feature extractor.
