    This study introduces a novel method for motion field estimation using long-exposed images alongside traditional short-exposed ones. This approach enhances accuracy and robustness, enabling better tracking of occluded objects.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Motion Estimation

    Background:

    • Traditional optical flow algorithms depend on short-exposed images, limiting accuracy and robustness.
    • Estimating motion fields, especially with occlusions, remains a challenge in computer vision.

    Purpose of the Study:

    • To develop a more robust and accurate motion field estimation method.
    • To leverage information from long-exposed images for improved motion analysis.
    • To accurately determine occlusion events and estimate motion in occluded regions.

    Main Methods:

    • Utilizing an additional long-exposed image in conjunction with short-exposed images.
    • Developing an image formation model that links long-exposed images with short-exposed ones.
    • Implementing a variational algorithm for dense 2D motion and per-pixel occlusion timing estimation.
