摘要： A method includes obtaining an image of a document against a background. A bounding box that bounds a region of the image that is distinguishable from the background is found. Coordinates of a plurality of points of the distinguishable region are found, each point being a point of the distinguishable region that is closest to each corner of the bounding box. The document is identified within the image as a region of the image whose corners are defined by the found coordinates.

摘要翻译： 一种方法包括基于背景获取文档的图像。 找到界定了与背景区别的图像区域的边界框。 找到可区分区域的多个点的坐标，每个点是最接近边界框的每个角的可区分区域的点。 文档在图像内被识别为图像的区域，其角由所找到的坐标定义。
