Real-time optimization of Viola -Jones face detection for mobile platforms
Jianfeng Ren, Nasser Kehtarnavaz, Leonardo W. Estevez · 2008
Face detection algorithms based on the Viola-Jones object detection approach is widely adopted in digital camera products. Due to the computational complexity of these algorithms, often a hardware coprocessor is used for their real-time operation. This paper discusses how to achieve real-time software-based implementation of these algorithms on mobile devices that have relatively limited processing and memory capabilities. Various optimization techniques are discussed and an example implementation outcome on an actual mobile platform is presented.
