| Outline of Final Research Achievements |
This study proposed a semiautomatic method for concrete surface cracks extraction from digital images. The characteristic feature of the method was the combination of interactive genetic algorithm (iGA) and touchscreen. The iGA was applied to optimize image processing parameters for each image without knowledge of image processing techniques. The touchscreen enabled the user to touch images directly and extract cracks smoothly. In order to show the capability of the software which implemented the proposed method, concrete surface cracks were extracted from digital images with reasonable accuracy and processing time.
