利用小波变换进行海上目标识别研究

对海面舰船目标类型的识别,通常采用目视判读的方法。由于目视判读的方法不利于大面积侦察任务的快速识别,所以根据海上目标所具有的背景单一、结构复杂的特点,提出了利用小波变换所具有的多分辩率、易于消除噪声、运算方便的特点来提取舰船边缘特征,建立舰船结构特征数据库,实现舰船目标类型的自动判读。试验证明效果很好。

Sea target recognition by wavelet transform

The methods that identify ship's type on ocean surface, usually adopt interpretation with eyes. This method is disadvantage to identify quickly target in the big area.According to characteristic that goal background is unitary and has complex structure, using wavelet transform has characteristic of multi resolution?easy to limit noise and operation convenience, it is very good to draw ship structural edge feature, and establish the database of ship construction characteristic,and auto distinguish warship ship type. The experiment shows that effect is very good.
