| 摘 要： | 为实现水声图象中沉底目标的自动探测，提出一种匹配滤波和分形检测相融合的方法。由于匹配模板能够较好地模拟沉底目标的成像特性，而分形模型有助于区分人工目标和自然背景，所以这两种方法的融合可以有效地检测出目标，减少虚警。

| Abstract: | In order to detect the object in seabed in underwater acoustic image automatically,a synchro method based on matched filter and fractional detection is proposed in this paper. The matched filter can perfectly simulate the image characters of underwater object,and the fractional model can distinguish the man-made object from nature background.So combining the two method can better detect object, reducing false probability . |
