Dynamic Positional Trees for Structural Image Analysis
Proceedings of the Eighth International Workshop on Artificial Intelligence and Statistics, PMLR R3:286-292, 2001.
Dynamic positional trees are a significant extension of dynamic trees, incorporating movable nodes. This addition makes sequence tracking viable within the model, but requires a new formulation to incorporate the prior over positions. The model is implemented using a structured variational procedure, and is illustrated on synthetic raytraced images and image sequences.
