Abstract: Embodiments of this application disclose a method and an apparatus for determining an image loss value, a storage medium, and a program product, and belong to the field of image compression technologies. In this method, loss values of different areas in an image are determined based on a partition indication map of the image, and then a total loss value is determined based on the loss values of the different areas. The partition indication map may be used to distinguish between a heavily-structured area and a lightly-structured area in the image, that is, the partition indication map may be used to distinguish between an edge structure and a texture. When the total loss value is used to assess image reconstruction quality, the image reconstruction quality can be assessed more comprehensively, and assessment of reconstruction quality of the edge structure and the texture can be maximally prevented from mutual impact.
