In view of the limitations of OTSU algorithm, an algorithm for salience based local recursive OTSU segmentation (SBLR OTSU) is proposed. The main technique of SBLR OTSU consists in that the object area resulting from OTSU is regarded as the whole image to be segmented at the next OTSU segmentation. The process goes on sequentially until definite conditions are satisfied. Then all the object areas resulting from OTSU are accumulated to yield the image of segmentation results. It is shown by experimental res...
