A GPU Based Implementation of Robust Face Detection System

Face detection is the active research area in the field of computer vision because it is the first step in various applications like face recognition, military intelligence and surveillance, human computer interaction etc. Face detection algorithms are computationally intensive, which makes it is difficult to perform face detection task in real-time. We can overcome the processing limitations of the face detection algorithms by offloading computation to the graphics processing unit (GPU) using NVIDIAs Compute Unified Device Architecture (CUDA). In this paper, we have developed a GPU based implementation of robust face detection based on Viola Jones face detection algorithm. To verify our work, we compared our implementation with traditional CPU implementation for same algorithm.
