Live-wire type techniques for interactive image segmentation are of practical use for various applications such as medical image analysis. digital image composition. etc, Intelligent scissors [5] and live wire [8] are the representative techniques,, of this type, which are based on a graph search over an entire image. Another technique called live lane [8] is also based on a graph search but localizes the search domain to give in interactive feedback. Compared to the live wire, the live lane trades off the repeatability of segmentation for its time efficiency. In this paper. we present a novel image segmentation technique called enhanced modified lane, a modified version of the live lane that ensures both efficiency and repeatability. B restricting the search domain and Updating the path map incrementally. the enhanced lane can extract objects from an image interactively with its efficiency comparable to that of the live lane while also keeping its repeatability comparable to that of the Iive wire, Based on the live lane paradigm, our technique also differs from the time-efficient version of live wire callcd live wire on the fly [9]: the enhanced lane always guarantees strictly bounded response time regardless of the image size and follows the target boundary with little digression which leads to better repeatability.
