    摘要: A filter system can effectively filter images with low computation cost by, instead of using large 2D filters, applying a series of smaller filters that require less compute and memory. In some implementations, the larger filter function, f, is replaced by f 1 , f 2 , ..., f N where f(x) ≈ f 1 ( x ) + f 2 ( x ) +... + f N ( x ) . The filter system can apply these filters sequentially across multiple frames in time. The time integration of information by the human visual system results in the perception of a single higher quality filtering result, while using only the compute and memory footprint necessary to implement the filters. The number of frames across which a filter can be split without introducing flicker artifacts is dependent on the refresh rate of the display.

    摘要: This application discloses an image processing method and apparatus, and a storage medium, and relates to the field of video image processing, to support different image layering methods, provide a flexible image fusion manner, and help improve image processing effect. The method includes: parsing an original bitstream of a to-be-processed image to obtain the to-be-processed image; parsing a first layered bitstream of the to-be-processed image to obtain a first layered image of the to-be-processed image; determining a second layered image of the to-be-processed image based on the to-be-processed image and the first layered image, where the first layered image is a base layer image, and the second layered image is a detail layer image; or the first layered image is a detail layer image, and the second layered image is a base layer image; performing tone mapping on the base layer image to obtain a mapping result of the base layer image; and fusing the mapping result of the base layer image and the detail layer image.
