Though it is roughly recognizable for the outlines of regional structure and volcanic rocks, the images of steep dip strata and boundary of volcanic rock are smeared.
结果超声内镜下胰头癌主要表现为边界不清晰（22/32）的低回声（21/32），伴有胆总管和胰管的扩张（19/36）、血管的侵犯（26/32）；
The tumor displayed the character of low echo (21/32), obscure boundary(22/32), vascular invasion (26/32), pancreatic duct and common bile duct dilation (19/36).
但由于目前在MAP算法中普遍采用的是平滑型图像先验模型，导致重构出来的图像边界不明锐，一些细节不清晰。
However, due to the use of smooth prior image model in MAP, the reconstructed edges and some image details are blurred.
当数据集聚类边界不清晰或存在噪声干扰时，人工免疫网络聚类算法通常无法获得有效的聚类划分。
Artificial immune network clustering is often ineffective when there is noise or undefined cluster boundary in the data.
