This paper according to the data format on
hardware system established the YUV color space skin
color model, improved the traditional region labeling
algorithm. After merge and divided algorithm,
eliminated the small skin region, integrated face’s
aspect ratio and characteristic distribution we can
locate all face region in complex background.
Test results showed that, the multi-face location
algorithm based on embedded DSP image system can
detect most skin pixels. Through labeling and merging
the skin color region we can locate the multi-face
regions quickly and accurately. Therefore it can be
successfully used in video monitoring, target tracking
or other application domains
