The DMPAC optical flow processing requires multi-level Gaussian Image Pyramids for implementing coarse-to-fine refinement method during pixel correspondence search. However, the DMPAC does not implement the logic required to build this image pyramid. It requires some SoC level external logic to build and store the image pyramid in external SDRAM (DDR).
The DMPAC optical flow processing requires/uses the following features for the image pyramid:
As shown in Figure 6-157, DMPAC SoC Level Dataflow for Optical Flow Pre-Processing, the sclare module (MSC) in VPAC is responsible to generate the image pyramid.
