| 摘要 |
The invention discloses a method and apparatus for hand detection, wherein the method for hand detection comprises: calculating a current skin difference image by using a previous skin image and a current skin image; calculating a first threshold by using the current skin image, calculating a fourth threshold by using the current skin difference image, and calculating a second threshold and a third threshold by using the first threshold and the fourth threshold; segmenting a foreground image from the current skin difference image by using the first to fourth thresholds; and performing hand detection taking the foreground image segmented from the current skin difference image as a search scope; in the method and apparatus for hand detection based on embodiments of the invention, searching scope of hand detection process is narrowed by foreground segmenting, so that the number of cycles needed for performing a hand detection is reduced. |
