边缘信息 [遥感] marginal information
- 提出了一种在红外图像中结合局部概率和边缘信息的点目标检测方法。
A method of small target detection is presented in IR images which combining local probability and edge information of the image. - 然后计算目标区域中心像素的边缘信息,进一步剔除强边缘噪声点,检测小目标。
Then, computes the edge information of the central pixels in every object area to eliminate strong edge noises and detect small target. - 提出了一种基于径向小波变换的图像特征提取算法,该方法使用径向对称函数来获得图像的边缘信息。
A wavelet-radial algorithm for invariant feature extraction is given by the wavelet techniques and the edge information is obtained using the radial symmetric functions.
