【摘要】 本文根据Ｂ超图象的灰度特性，选用象素的相对灰度等级作为模糊特征，在对图象作灰度线性变换和中值滤波的基础上，采用模糊算法实现Ｂ超图象的模糊增强处理。实验表明通过调节模糊参数可显著提高图象的增强效果。更多还原

【Abstract】 s According to the gray properties of B mode image, relative gray grade of pixel was selected as fuzzy feature. On the basis of gray linear transformation and median filtering, fuzzy enhancement of B mode image was realized by using fuzzy algorithm. Experimental results show that remarkable improvement of enhancement effect was obtained by adjusting fuzzy parameter.更多还原
