Abstract
An image filtering method and apparatus, where the method includes determining a filter coefficient of a chroma filter based on a filter coefficient of a luma filter, where the luma filter and the chroma filter are respectively applied to perform filtering processing on luma samples and chroma samples of a to-be-processed image, all filter coefficients of the luma filter present a first geometric distribution, all filter coefficients of the chroma filter present a second geometric distribution, the first geometric distribution and the second geometric distribution are similar shapes, and a filter coefficient of the chroma filter at an edge of the second geometric distribution is calculated using one or more filter coefficients of the luma filter at an edge of the first geometric distribution, and respectively performing filtering processing on the luma samples and the chroma samples using the luma filter and the chroma filter.
