Abstract
Disclosed is an object detection method and system in an image plane. A Hidden Markov Model (HMM) is employed and its associated parameters are initialized for an image plane. Updating HMM parameters is accomplished by referring to the previous estimated object mask in a spatial domain. With the updated HMM parameters and a decoding algorithm, a refined state sequence is obtained and a better object mask is restored from the refined state sequence. Consequently, estimation of the HMM parameters can be rapidly achieved and robust object detection can be effected. This allows the resultant object mask to be closer to the real object area, and the false detection in the background area can be decreased.
