A New Approach to Morphological Method by Anytime Algorithm for Real-time Image Processing

Abstract

Real-time system requires not only the perfect result but also the partial usable result which produces in time under time restriction. Morphological method is a tool for extracting image components that are useful in the representation and description of region shape, such as boundaries, and skeletons, which are especially applied in image preprocessing. This paper proposes a new approach to morphological method using anytime algorithm for boundary extraction. First, multi-structuring elements are constructed by changing the direction. Then,morphology erosionoperation usingmulti-structuring element is performed step by step by using the previous result as input at current stepaccording to the concept of anytime algorithm. We can confirm the effectiveness of proposed method by the experimental resultswith coarse-to-fine results and the quality of results improves when the processing time increases. This gives an idea to solving the time quality trade-off problem in real-time image processing.
