| 摘 要： | 图像二值化是数字图像处理系统中基本而关键的技术，阈值分割是实现二值化的重要途径，假定图像的目标与背景是可以分离且存在一定差异的，则基于图像中目标和背景与原图像的差异，建立恰当的差异度公式。提出相应的算法，并对太阳像进行闽值分割。试验结果表明，与一些传统方法相比，该方法能很好地区分目标和背景，得到了较好的二值化处理效果。

| Abstract: | Image binaryzation is a basic and key technique in the digital image processing system, threshold segmentation is an important way to realize binaryzation, the object and background of the assumption image can be separated and have some differences. A new algorithm is introduced based on the differentiation of object and background, and an appropriate difference formula is established to segment the solar image. The experimental result shows that this algorithm can segment the object and background, and achieves the intended treatment effect. |
