摘要
Background subtraction technique has been widely used in the single camera based multi-touch system. The solution based on fixed-rate background accumulation can only be used to the applications with gradual change of ambient lightings. This paper presents a solution to update background by detecting ambient lightings, which enables the multi-touch system to be operated under the conditions of rapid or complicated change of ambient lightings. Experimental results show that with the help of the presented solutions, the ghost points are efficiently reduced and the system can adapt to the changes of ambient lighting in 1 second.
