| 摘 要： | 提出基于小波变换的多源图像数据融合和边缘检测的方法,对多源图像进行分解,将高频区域中的绝对值较大的系数作为重要小波系数;在低频区域,对逼近系数进行加权平均得到新的逼近系数,然后进行小波重构实现多源图像数据融合。应用小波变换对融合图像进行多尺度边缘检测,获取多源图像边缘,或对多源图像进行小波多尺度边缘检测,然后融合边缘。

| Abstract: | A mothed for multiresolution image data fusion anedge detection besed on wavelet transform is presented, by mutiresolution image analysis, to regard the coefficients with largeabsolute value in high frequency range as the important wavelecoefficients and the weighted mean value of approximation coeffcients in low frequency range as approximation coefficients, thimage data fusion can be obtained using the inverse waveletransform. The edges from fused image are detected or the edgefrom multiresolution image are fused using wavelet multiscaedge detection. |
