Abstract
To provide a device and method for counting the number of wires of Image quality Indicators (IQI) by image processing in order to evaluate the quality of a radiographic testing film image.SOLUTION: A method for evaluating quality of a radiographic testing image includes: when a wire area image is input which is an image of an area where wires of image quality indicators exist in a radiographic image of a target object with one or more image quality indicators attached thereto through radiation, a step of preprocessing, by a preprocessing unit, the wire area image; a step of binarizing, by a binarization unit, the wire area image; a step of detecting, by a line detection unit, lines in the wire area image; a step of counting, by a counting unit, the number of wires of the image quality indicators according to the detected lines; and a step of evaluating, by an evaluation unit, the quality of the radiographic image according to the number of counted wires.SELECTED DRAWING: Figure 2
