摘要： An image processing method is disclosed. The image processing method may include: partitioning an original gridded image to obtain a plurality of regional grid images, wherein the regional grid images are distributed along a direction away from a geometric center of the original gridded image (S300); and adjusting grid vertices of the regional grid images based on anti-distortion parameters to obtain a plurality of regional correction grid images forming a grid correction image (S400). A grid density of each of the regional correction grid images may be smaller than or equal to a grid density of a corresponding regional grid image, and the grid density of each of the plurality of the regional correction grid images may gradually increase along the direction away from the geometric center of the original gridded image.

摘要： This disclosure provides a cache replacing method applied to a heterogeneous multi-core system, the method including: determining whether a first application currently running is an application running on the GPU; when it is determined that the first application currently running is an application running on the GPU, determining a cache priority of first data accessed by the first application according to a performance parameter of the first application, the cache priority of the first data including a priority other than a predefined highest cache priority; and caching the first data into a cache queue of the shared cache according to a predetermined cache replacement algorithm and the cache priority of the first data, and replacing data in the cache queue.
