Abstract: An image processing method is provided. The method includes a first MCNR stage and a second MCNR stage. The first MCNR stage includes blending the current frame with either a cached image or a long-term reference image to obtain a fused image. The cached image is loaded from the buffer unit, and the long-term reference image is derived from the static region of each input frame in a sequence of input frames. The second MCNR stage includes blending the fused image with the other of the cached image or the long-term reference image to obtain an output image.

Abstract: An image processing method is provided. The method includes the step of comparing each of the input pixels in an input image to a corresponding buffered pixel in a buffered image, and computing the difference value between the input pixel value of the input pixel and the buffered pixel value of the buffered pixel. The method further includes the step of generating a blended image based on the input pixel values and the corresponding difference values. The method further includes the step of determining whether a criterion associated with the difference value is met, for each of the difference values. The method further includes the step of updating, for each of the buffered pixels in the buffered image, the buffered pixel value based on the corresponding input pixel value if the criterion is met, and keeping the buffered pixel value unchanged if the criterion is not met.
