Original Abstract Submitted
An image subsampling method and an apparatus, which relate to the technical field of image processing. The method comprises: acquiring a target image and a subsampling rate; determining a subsampling interval to which the subsampling rate belongs; when the subsampling rate belongs to a first subsampling interval, performing subsampling on the target image by using a first subsampling algorithm; and when the subsampling rate belongs to a second subsampling interval, performing subsampling on the target image by using a second subsampling algorithm; the second subsampling interval is greater than the first subsampling interval; the performance overhead of the second subsampling algorithm is greater than the performance overhead of the first subsampling algorithm; and at an identical subsampling rate, the image quality of a subsampled image obtained by the second subsampling algorithm is higher than the image quality of a subsampled image obtained by the first subsampling algorithm.
