B超图象的二维Otsu快速自动分割

A Fast Segmentation of B-Scan Ultrasonic Images Via Two-Dimensional Otsu Method

本文基于Ｏｔｓｕ原理，将一维Ｏｔｓｕ多门限推广到二维Ｏｔｓｕ多门限，实现了灰度图象中多个目标的自动分割，使分割效果更佳且抗噪声能力增强；提出了二维Ｏｔｓｕ多门限的快速算法，并应用于Ｂ超图象的分割，获得了较为理想的结果。

n this paper,a fast two-dimensional Otsu multithresholding algorithm is proposed. It is an eatension of one-dimensional Otsu multi-thresholding. This algorithm is applied to segment B-SCAN ultrasonic images and the results of segmentation are satisfactory.
