    • A method is provided for speeding up a super-resolution processing by reducing the number of times for convolution operation that is the number of times for estimation calculation.
      A fast method of super-resolution processing for speeding up a super-resolution processing that estimates a high-resolution image from multiple low-resolution images with a displacement, which comprising: a first step for performing a registration of said multiple low-resolution images in a high-resolution image space and treating all pixels of said multiple low-resolution images after the registration as pixels sampled at unequal interval within said high-resolution image space; a second step for dividing said high-resolution image space into multiple small areas with a predefined size; and a third step for defining an estimated value at a predefined representative position within said small area as an estimated value of all pixels that exist within said small area for each small area divided in said second step.
    • 提供一种通过减少用于估计计算次数的卷积运算次数来加速超分辨率处理的方法。 一种超分辨率处理的快速方法,用于加速从具有位移的多个低分辨率图像估计高分辨率图像的超分辨率处理,其包括:第一步骤,用于执行所述多个低分辨率图像的注册 在高分辨率图像空间中,并且将所述多个低分辨率图像的所有像素在所述注册之后处理为在所述高分辨率图像空间内以不等间隔采样的像素; 用于将所述高分辨率图像空间分割成具有预定尺寸的多个小区域的第二步骤; 以及第三步骤,用于在所述小区域内的预定代表位置处定义估计值,作为在所述第二步骤中划分的每个小区域,存在于所述小区域内的所有像素的估计值。
