Abstract

A hardware design of shape-preserving contour tracing for objects in a segmented image for robot vision and pattern recognition applications is presented in this paper. The proposed contour tracing consists of two processes, namely progressive boundary linking (PBL) and synchronous redundancy pruning (SRP). The proposed method is realized on a System on Chip (SoC) with open-source processor IP core, LEON3, utilizing AMBA bus. Implementation results show that the proposed design achieves better results in terms of accuracy and hardware efficiency comparing with other existing boundary extraction methods such as morphological boundary extraction.
