Gesture detection and recognition method and system

A gesture detection and recognition method, wherein:

• the method comprises the steps of:
• A1. collecting images and storing the images;
• A2. using preset multiple classifiers used for detecting different gestures to detect each frame of the images in a way of alternating every two frames in preset order, to acquire gesture targets;
• A3. establishing skin color models based on pixel distribution in target area of the gestures;
• A4. acquiring gesture frequency of said gesture target in two consecutive states according to the skin color model, and match said gesture frequency with preset gesture state, to acquire gesture transition state and output.

A gesture detection and recognition system, wherein:

• the system comprises:
• an acquisition unit for collecting images;
• a storage unit connecting to said acquisition unit for storing said images;
• a plurality of classifiers for detecting different gestures connecting to said storage unit for detecting each frame of said images in a way of alternating every two frames in preset order, to obtain gesture target;
• a skin color modeling unit connecting to said storage unit for establishing skin color models based on pixel distribution in said target area of the gestures;
• a decision making unit connecting to a plurality of said classifiers and said skin color modeling units respectively, acquiring said gesture frequency of said gesture targets in two consecutive states according to the skin color model, and match said gesture frequency with preset gesture state, to acquire gesture transition state and output.

A gesture detection and recognition method, comprising the steps of:

• providing an acquisition unit and a storage unit;
• acquiring, and storing a plurality of images;
• providing a plurality of pre-set classifiers for detecting different gestures to detect each frame of of said plurality of images according to a pre-set sequence in a frame alternating manner and acquiring a gesture target;
• providing a skin color modeling unit based upon a pixel distribution of a region of said gesture target;
• and
• providing a a decision-making unit that acquires gesture frequencies of said gesture target in one of a previous state and a later state according to said skin color modeling unit.
