Explore visually: Dual TV-L1 optical flow →

Estimate flow with a robust data term and a total-variation smoothness penalty.

VISUAL WALKTHROUGHMotion

REFERENCE INPUTTwo consecutive frames

The object moves right and upward; most of the background remains still.

→

RESULTDense displacement field

Mint vectors follow the moving object. Grey vectors represent the nearly static background; each vector belongs to an image location.

Illustrative example. The stages explain the method; they are not a live OpenCV execution.

Creates instance of cv::DenseOpticalFlow

optflow_createOptFlow_DualTVL1(): optflow_DualTVL1OpticalFlow | null;

Returns

The optflow_DualTVL1OpticalFlow | null result.
