5.2. Related Work

Perceptual organization has been an active research area. Important issues include noise robustness, initialization requirements, handling of discontinuities, flexibility in the types that can be represented, and computational complexity. This section reviews related work, which can be classified in the following categories:

- regularization

- relaxation labeling

- computational geometry

- robust methods

- level set methods

- symbolic methods

- clustering

- methods based on local interactions

- methods inspired by psychophysiology and neuroscience

Regularization

Due to the projective nature of imaging, a single image can correspond to different scene configurations. This ambiguity in image formation makes the inverse problem, the inference ...
