Abstract: This paper presents a framework for constructing image interpretation in a distributed problem solving environment. The interpretation of an image is constructed using abductive inferencing scheme. The inferencing mechanism ensures generation of interpretations of the image which can account for the features detected in the image in the most consistent manner. Two different decomposition strategies have been discussed for identifying the eubproblems. Strategies have been formulated for solving the subproblems and integrating the partial results in a parallel and distributed fashion. Correctness and validity of the strategies have been proved. A black board model based distributed architecture have been shown to satisfy the requirements of the problem solving technique.

TL;DR: The problem of detecting correspondences between object contours belonging to successive image frames of a dynamic scene is addressed using heuristic search with a state space formulation and an admissible heuristic function is designed for guiding the search.
Abstract: The problem of detecting correspondences between object contours belonging to successive image frames of a dynamic scene is addressed. The object contours are represented using concave, convex, and straight line segments which are extracted after smoothing the contour with a Gaussian kernel. The matching problem is tackled using heuristic search with a state space formulation. An admissible heuristic function is designed for guiding the search. Experimental results are presented to demonstrate the capabilities of the method.
TL;DR: A new technique is proposed for detection of corners in images of polygonal objects on the principle of ‘hypothesize and test’ and initial hypotheses about the method are made.
