Query: Compact Convolutional Neural Network Cascade for Face Detection   The problem of faces detection in images or video streams is a classical
problem of computer vision. The multiple solutions of this problem have been
proposed, but the question of their optimality is still open. Many algorithms
achieve a high quality face detection, but at the cost of high computational
complexity. This restricts their application in the real-time systems. This
paper presents a new solution of the frontal face detection problem based on
compact convolutional neural networks cascade. The test results on FDDB dataset
show that it is competitive with state-of-the-art algorithms. This proposed
detector is implemented using three technologies: SSE/AVX/AVX2 instruction sets
for Intel CPUs, Nvidia CUDA, OpenCL. The detection speed of our approach
considerably exceeds all the existing CPU-based and GPU-based algorithms.
Because of high computational efficiency, our detector can processing 4K Ultra
HD video stream in real time (up to 27 fps) on mobile platforms (Intel Ivy
Bridge CPUs and Nvidia Kepler GPUs) in searching objects with the dimension
60x60 pixels or higher. At the same time its performance weakly dependent on
the background and number of objects in scene. This is achieved by the
asynchronous computation of stages in the cascade.
