186 The Application of Digital Image Processing in Freight Train Inspection System Available to Purchase

In this paper, we proposed a novel application based on digital image processing model in Freight Train Inspection (FTI) system. Each wagon image of freight train is captured by enterprise Automated Train Scanning System (ATSS). The main challenge of this application is automatically detecting the appropriate region of interest on the image for inspection. To address this problem, the improved adaptive multi-scaled retinex (MSR) and K-mean clustering methods are applied for image enhancement and positioning techniques. In the experimental the proposed model were found to improve the segmentation efficiency, thereby the result of inspection is optimized. The evaluation result also demonstrated the good system performance when the application is implemented using Vision Services Oriented (VSO) framework.
