PAN Mei-sen, RONG Qiu-sheng. Image fusion binarization method based on SOFM neural network[J]. Optics and precision engineering, 2007, 15(3): 401-406.DOI:
An image fusion binarization method based on Self-organization Feature Map(SOFM) neural network is presented. The characteristic and the learning algorithm of SOFM neural network are introduced. The first threshold of the image is derived from the clustering characteristic of SOFM
and it is treated as a initialization of the circulated iteration method to obtain the second threshold of the image. The binarization for the original image is carried on using the second threshold to obtain the first fusing image. Then
the binarization for the original image is performed more again using the improved Bernsen method to obtain the second fusing image. Finally
two fusing images are merged based on the minimum principle of image gray values to get the final binarization image. This method can effectively eliminate the ghost and can also separate the characters very well. Experimental results show that the method is effective
and its binarization effect surpasses Bernsen method and Ostu method obviously
moreover it has good compatibility.
