Based on the fingertips of thinking image tracking algorithm is proposed.In constraint conditions

the bayesian statistical simplifying constraint problems

according to the principle of the bayesian filter

with the image characteristics of based on bayesrule to calculate the posterior probability

to normalized processing of image characteristics

and through the establishment of color skin probability information of statistical model

simplify the tracking process.Experimental results show that the improved algorithm to image tracking at your fingertip

can improve the detection accuracy and robustness.
