Using motion tracking and image categorization for document indexing and validation

摘要

Systems and methods include an application operating on a device. The application causes the graphic user interface of the device to display an initial instruction to obtain a full-view image that positions all of an item within a field of view of a camera on the device. The application automatically recognizes identified features of the full-view image, by using a processor in communication with the camera. After displaying the initial instruction, the application causes the graphic user interface to display a subsequent instruction to obtain a zoom-in image that positions only a portion of the item within the field of view of the camera. Also the application automatically recognizes patterns from the zoom-in image, using the processor. Furthermore the application performs an authentication process using the identified features and the patterns to determine whether the item is valid, using the processor.

主权项

1. A method of authenticating a physical item having markings using a portable computing device comprising:
causing a graphic user interface of said portable computing device to display an initial instruction to obtain continuous video and position all of said physical item within a field of view of a camera of said portable computing device; automatically recognizing identified features from said markings of said physical item from a full-view video frame of said continuous video obtained when all of said physical item was within said field of view of said camera, using a processor in communication with said camera; after displaying said initial instruction, causing said graphic user interface to display a subsequent instruction to zoom in on said physical item and position only a portion of said physical item within said field of view of said camera while continuing to obtain said continuous video; automatically recognizing patterns from a zoom in video frame of said continuous video obtained when only said portion of said physical item occupied all of said field of view of said camera, using said processor; monitoring said continuous video for continuity while continuing to obtain said continuous video to determine whether said continuous video is continuous or discontinuous between said full-view video frame and said zoom in video frame; repeating said initial instruction followed by said subsequent instruction when said continuous video is determined to be discontinuous; and performing an authentication process using said identified features and said patterns to determine whether said physical item is valid when said continuous video is determined to be continuous by matching said identified features and said patterns to previously validated data, using said processor.
