中文摘要	An edge-based algorithm was developed for real-time text string location in images with significant noise. The method uses an edge density graph and the edge linkage intensity. The algorithm first makes a top-down coarse location using the projection analysis of the edge density graph and then makes a bottom-up precise location based on the vertical edge linkage intensity. The algorithm effectively overcomes the influence of noise and has low computation cost, so it can be used for real-time text string location in images with noise. The algorithm has been adopted to locate serial number strings in wafer images; the experiment results prove its effectiveness.
