Abstract
A system for capturing and identifying an image includes an image-capturing unit and an image-identifying unit. The image-capturing unit is adapted to capture a single image by a single photo. The image-identifying unit is electrically connected with the image-capturing unit, and is adapted to identify the single image and provides related assistant learning information desired by a reader, based on the identifying result. The captured image is identified, including the steps of removing the interference with light with estimation of parameters of a light curve, dividing characters, normalizing characters and comparing features. The system can be used for capturing the information about a question of a test paper. A question of the test paper has a mark-code image. After captured, the mark-code image can be identified to attain mark-code characters. Based on the mark-code characters, related information is provided.
