    Abstract:

    Aiming at the problem of defect image character recognizing on steel ball, the improved method of run length coding was used in registering bug area of steel ball surface to disjoin defect region and irrelevant region after image was segmented. As a result, steel ball was detected by area character parameter. The program of image processing, segmentation, recognizing was developed in LabVIEW platform. This means has already been tested and it shows the algorithm has practicability, reliability and precision.
