Abstract— In this paper, a parallel image-processing method based on OpenMP is proposed for a software application in a fire-control system(FCS). The proposed method for image-processing is composed of automatic and semi-manual detection methods respectively. In the automatic method, a target is detected automatically by the image-processing dynamically for moving target in CCD with IR for bright target. For the performance evaluation, the proposed method is compared with a CUDA and normal image processing. The simulation results show that, the proposed method has good performance in term of total image processing time in the FCS.
