摘要
特征提取中,由于地物特征的差异及其它因素的影响,提取的目标大多是非连续的,这将导致提取的目标与实际情况不符合,若不进行恢复,势必影响对目标性质的认识和应用。本文基于数学形态学方法,首先对二值图像中非连续的线性目标进行了分析和处理,然后对结构元素的选取和分解进行了阐述。最后的实验结果表明,该方法效果较好。
During the course of feature extraction, the objects which are extracted are always discrete because of the difference of the same object and other factors, which will result in the objects extracted can not reflect the real fact ac- tually. If the discrete can not be resumed, the incorrect result will affect the comprehension and application to the ob-jects. The research analyse and process discrete linear objects, then select and decompose structural element about bi- nary based on Mathematics Morphology. The result of the experiment indicate this method can achieve a desired result.
