i know how optimise data-structures in opencv (the mat type specifically) able leverage operating systems built in memory/virtual memory management. for full context please read q , here - otherwise situation summed have large collection of mats * i'll need access arbitrarily , rapidly . main complication full amount of data above amount of ram available. (*conceptually data recursively defined 3d array of 3d arrays, let's not muddy water confusion!) rather build own lru cache , ram-hungry , inefficient 'page' addressing strategies access it, i'd rather let os me. i think concepts, when comes actual implementation i'm twiddling thumbs: is generic c++ consideration, or need address @ opencv level? is simple making granularity of of data close (but not over) 4kb? (see solution here 4kb motivation) how mat(s) saved, accessed , represented on disk? (is how memory-mapping involved?) is generic c++ consideration, or need address @ op...
