Two dimensional Otsu image segmentation algorithm based on adaptive weighted median filter
The traditional two dimensional Otsu image segmentation algorithm got ineffectively result in the image segmentation while the image contains lots of noise.To solve the problem,this paper proposed a new two dimensional Otsu image segmentation algorithm based on adaptive weighted median filter.This method firstly preprocessed the image with noise by a new adaptive weighted median filter,then transferred the region division in two dimensional histogram of median image from four partitions into two partitions,finally segmented the image accurately by an improved two dimensional Otsu algorithm.The experimental results show that the proposed algorithm has better anti noise performance and better segmentation result for image with noise.
