Chromatic shadow detection and tracking for moving foreground segmentation

作者:

Highlights:

• We address the detection of chromatic moving shadows.

• Gradient and colour information is exploited for separating shadow regions.

• Temporal gradients and spatial angle and brightness distortions are used to detect shadows.

• Shadows and objects are tracked using motion filters.

• Mutual information and data association between objects and shadows are used to recover misdetected shadows.
