摘要
针对毫米波辐射图像分辨率低的问题,提出了一种新的分辨率增强方法.该方法将双线性插值与改进的非线性外推相结合,首先利用双线性插值放大原始图像,再利用改进非线性外推算法增加图像的高频分量,最终实现毫米波辐射图像的分辨率增强.实验表明,新方法有效提高了毫米波辐射图像的分辨率.
Aimed at the problem of low resolution of millimeter wave radiometric image,a new resolution enhancement method is proposed. This method, which combines bilinear interpolation and improved inear extrapolation inear extrapolation limeter wave radiomete , utilizes bilinear interpolation to amplify original image,and then utilizes improved to increase high frequency components of the image, lastly, the resolution of milr image is enhanced. Experimental results show that the new method can improve the resolution of millimeter wave radiometric image effectively.
