Misregistration Correction for Moving Object Scene in Filter-type Multispectral Imaging
摘要
Abstract
Image registration is a key step for multispectral camera to obtain multispectral data cube. The impact of moving objects on im-age registration for filter array type multispectral camera was analyzed. To solve the problem,a method based on the detection of moving vehicles to correct the misregistration is presented. Firstly,the potential regions of misregistration pixels are roughly extracted by change detection,and then the misregistration pixels are screened through the features of moving objects,and these pixels are corrected based on the relationships of space and gray level among the multispectral image sequences. The method is applied to process the multispectral im-age obtained with an 8-channel filter array multispectral camera. The experimental result indicates that the approach could fix the wrong matches effectively and improve the accuracy of multispectral imaging registration. The processed images would be more favorable to im-age interpretation,the classification of multispectral image,object recognition and other subsequent applications.关键词
