摘要
提出了一种基于高斯小波变换的航空红外图像的目标边缘自动提取的新方法,并利用目标边缘特征结合目标边缘特征数据库对目标进行识别。该方法利用小波变换良好的噪声抑制能力及完备的边缘保持能力;能够有效的对红外图像进行目标边缘提取、目标增强及噪声抑制等预处理工作,利用得到的边缘特征及数据库,较好的完成红外目标的多尺度识别。
A new way based wavelet transform for edge detection of infrared airscape is proposed,and using edge characteristics database to recognize objecto of airscape.The way using favourable restrain ability to yawp and selfcontained keep ability to edge of wavelet is efficiency to detect edge of infrared airscape targets,enhance the targets and restrain noise,and it can finish multiscale recognition for airscape object well using edge charcteristics and database.
