Several aspects of human sensitivity for visual inspection

For long years, image processing researchers pay tremendous effort to develop visual inspection systems. To develop the visual inspection systems requires long and severe effort of image processing experts. But there is no method to evaluate the properness of the visual inspection system. In this paper, an attempt to evaluate the properness of the visual inspection system has been introduced. Also, human operators can detect the defects, very easily. Here, the visual inspection system with human operatorpsilas sensitivity simulator is discussed. To develop the simulator, the human sensitivity model for visual inspection should be accomplished. To have the model, several experiments to evaluate the human sensitivity have been required. In this paper, some experiences to evaluate the human sensitivity have been introduced, also.
