摘　　要：气象图像都是卫星远程采集的,图像放大后,气象图像像素个数不变,造成像素变形,变形后的像素很容易被破坏,导致放大后的气象图像清晰度不高,为此,提出一种基于滤波插值的放大图像处理算法;通过滤波计算,过滤放大后图像多余的噪声,然后对变形像素进行插值计算,补偿由于显示区域变大导致的像素变形,完整像素数量不足的缺陷,克服由于放大造成的图像清晰度下降的弊端;实验结果表明,该方法能够大幅提高气象图像放大后的清晰度,具有很强的实用性和推广价值。Meteorological satellite images are remote acquisition, image magnification, meteorological pixels, cause the same number of pixels deformation, after deformation pixel is easy to be destroyed, lead to enlarge the weather after image contrast is not high, in order to solve this problem, this paper proposes a interpolation filter algorithms, through the amplification of deformation calculation, pixel interpolation compensation display area bigger lead to the pixel deformation, complete the weakness of the number of pixels, overcome caused due to enlarge image contrast of the decline of the drawbacks. The experiment results show that the method can greatly improve the clarity of the meteorological after image magnification, good results.
