Title: IMAGE PREDICTION METHOD AND RELATED PRODUCT
Abstract:
Disclosed are an image prediction method and a related product. The image prediction method comprises: using a reference block to perform intraframe prediction on a current block so as to obtain an initial predicted pixel value of a pixel point in the current block; and performing weighting and filtering processing on the initial predicted pixel value of the pixel point in the current block so as to obtain a predicted pixel value of the pixel point in the current block, wherein weighting coefficients used in the weighting and filtering processing comprise a horizontal weighting coefficient and a vertical weighting coefficient, an attenuation rate factor acting on the horizontal weighting coefficient being different from an attenuation rate factor acting on the vertical weighting coefficient. The solution of the embodiments of the present application aids in increasing image prediction accuracy.
