Introduce

The GitHub repository “FocusFlow_official” presents FocusFlow, a framework designed to enhance key-point optical flow estimation for autonomous driving. The traditional data-driven optical flow methods often underperform in crucial key-point scenarios due to biased attention distribution. FocusFlow introduces a points-based modeling approach that explicitly learns key-point priors. The framework includes a mixed loss function combining photometric loss and Conditional Point Control Loss (CPCL) for diverse point-wise supervision. It employs a Condition Control Encoder (CCE) to replace the standard feature encoder, achieving remarkable precision improvement on various key points while maintaining competitive performance on entire frames.

Based on the modeling method, we present FocusFlow, a framework consisting of 1) a mix loss function combined with a classic photometric loss function and our proposed Conditional Point Control Loss (CPCL) function for diverse point-wise supervision; 2) a conditioned controlling model which substitutes the conventional feature encoder by our proposed Condition Control Encoder (CCE).
