Method of establishing adjustable-block background model for detecting real-time image object
A method of establishing an adjustable-block background model for detecting a real-time image object is provided to obtain a surveillance image by a surveillance apparatus. The surveillance image has a plurality of pixels. The method includes steps of: segmenting the surveillance image into a plurality of blocks each having a first pixel and at least one second pixel; defining the first pixel as a major color and comparing the first pixel with the at least one second pixel to determine a number and color information of the major color in the block; merging the blocks having the same major color into a large block to obtain a block background model; and performing image comparison to identify a moving object image. With the establishment of the block background model, a required memory space is effectively reduced while outstanding image display performance is still maintained.
