Abstract: Extracting financial card information with relaxed alignment comprises a method to receive an image of a card, determine one or more edge finder zones in locations of the image, and identify lines in the one or more edge finder zones. The method further identifies one or more quadrilaterals formed by intersections of extrapolations of the identified lines, determines an aspect ratio of the one or more quadrilateral, and compares the determined aspect ratios of the quadrilateral to an expected aspect ratio. The method then identifies a quadrilateral that matches the expected aspect ratio and performs an optical character recognition algorithm on the rectified model. A similar method is performed on multiple cards in an image. The results of the analysis of each of the cards are compared to improve accuracy of the data.

Abstract: Capturing an image of an object from a captured perspective and creating a plurality of candidate object areas. Each candidate object area potentially enclosing the object captured in the image. From the plurality of candidate object areas, a candidate object area is selected as enclosing the object. A corrected image of the object is generated based on the selected candidate object area. The corrected image shows the object transformed to a corrected perspective. The corrected image is displayed.
Abstract translation: 从拍摄的角度捕获对象的图像并创建多个候选对象区域。 每个候选对象区域可能包围在图像中捕获的对象。 从多个候选对象区域中选择候选对象区域作为封闭对象。 基于所选择的候选对象区域生成对象的校正图像。 经校正的图像显示被转换为校正透视图的对象。 显示校正后的图像。

Abstract translation: 以轻松对准的方式提取金融卡信息包括接收卡的图像的方法，在图像的位置确定一个或多个边缘查找器区域，并识别一个或多个边缘查找器区域中的线。 该方法还识别由所识别的线的外插的交点形成的一个或多个四边形，确定一个或多个四边形的纵横比，并将确定的四边形的纵横比与预期的纵横比进行比较。 然后，该方法识别与预期宽高比匹配的四边形，并在整流模型上执行光学字符识别算法。 在图像中的多个卡上执行类似的方法。 比较每个卡的分析结果，提高数据的准确性。
