Dense optical flow processing in a computer vision system

A method comprising:

• receiving an image that includes pixels;
• dividing a subset of the pixels into tiles, wherein each of the tiles includes a plurality of contiguous pixels and each of the tiles does not overlap with a remainder of the tiles;
• storing the tiles into banks of a memory, wherein adjacent tiles are stored in different banks;
• and
• performing a process on the image that includes reading the tiles from the banks.

A computer vision system comprising:

• an image generation device configured to generate an image that includes pixels;
• a memory that includes memory banks;
• and
• a dense optical flow engine coupled to the image generation device and the memory, wherein the dense optical flow engine is configured to determine a dense optical flow map for the image by:
• dividing the pixels into tiles that do not overlap;
• storing each of the tiles in a respective bank of the memory banks, wherein adjacent tiles are stored in different memory banks;
• and
• fetching the tiles from the memory banks.
