Embodiment Construction
[0081] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.
[0082] This embodiment introduces the specific implementation process of the form query condition input method for the application scenario where the form image is input as the query condition into the form classification system. The output is usually the text area in the form, and the next step of text recognition and input of the corresponding area information is performed. The input of the form here can be a scanned form or a form photo with better image quality, and supports form classification in multiple languages. The preprocessing of the input image uses hough transform for line detection and tilt correction, etc., and normalizes the form image to the same scale and angle as the training form image.
