摘要
提出了一种基于形态学Top-hat算子和目标形态特征以及空间关系知识处理的目标识别方法。该方法先对SPOT图象进行开Top-Hat和闭Top-Hat运算,以突出目标,抑制背景,然后根据目标固有的形态特征,对目标进行形态滤波,最后利用目标的空间关系特征进行进一步处理,去除虚假目标点。实验表明,该方法对复杂背景的SPOT图象上似圆状目标识别取得了良好的效果。
The Paper presents a new target recognition method, which is based on morphologic Top-Hat operator, morphologic characteristics and spatial relation along object. The method firstly do opening Top-Hat and closing Top-Hat operation for SPOT image, then filter by use of morphologic characteristics of object, lastly use spatial relation knowledge to remove redundant wrong object. When using the method to recognize circular object in complex background from SPOT image, the experiment suggests the method gain excellent effect.
