of_mm_cv_remap_affine
Affine and perspective warp engine
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 2
Matrix-driven affine and homography warps with bilinear interpolation for alignment and region of interest extraction.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
