3. REMARKS

    The equipment for creating negative pressure with suction force up to 10 kPa and air consumption up to 76 cubic meters per hour is used in this automatic tablet video inspection system.
    The video information analysis system includes two computing modules, receiving images from video cameras and processing them at speed of 25 frames per second. Each computing module is designed on the basis of Texas Instruments microprocessor TMS320VC5509A. In the below figures is shown how automatic tablet video inspection system detects various parameters of rejects.
    The result of window search by means of tablet video inspection machine in which the following search of an image of a tablet will be carried out is shown in figure 1.
