DeGraF-Flow: Extending DeGraF Features for accurate and efficient sparse-to-dense optical flow estimation

28 Jan 2019Felix StephensonToby BreckonIoannis Katramados

Modern optical flow methods make use of salient scene feature points detected and matched within the scene as a basis for sparse-to-dense optical flow estimation. Current feature detectors however either give sparse, non uniform point clouds (resulting in flow inaccuracies) or lack the efficiency for frame-rate real-time applications... (read more)
