5、se reduction平滑滤波器用于模糊处理和降低噪声/卷积Imageenhancement/imagerestorationimage Enhancement the process of manipulating an image so that the result is more suitable than the original for a specific application.图像增强处理是对图像进行的加工,使其结果对于特定的应用比原始图像更适合的一种处理。Image res
6、toration is an area that also deals with improving the appearance of an image. However, unlike enhancement, which is subjective, image restoration is objective.图像复原也是一个改进图像外观的一个处理领域,然而与图像增强不同,图像增强是主观的,图像复原是客观的。取样sampling:Digitizingthecoordinatevalues
