摘要： A system and method to classify forms. An image representing a form of an unknown document type is received. The image includes line-art. Further, a plurality of template models corresponding to a plurality of different document types is received. The plurality of different document types is intended to include the correct document type of the unknown document. A subset of the plurality of template models are selected as candidate template models. The candidate template models include line-art junctions best matching line-art junctions of the received image. One of the candidate template models is selected as a best candidate template model. The best candidate template model includes horizontal and vertical lines best matching horizontal and vertical lines of the received image, respectively, aligned to the best candidate template model.

摘要： A method of classifying an input image includes the initial steps of labeling an input image in accordance with a class and extracting at least one connected component from the input image. The method also includes the steps of calculating at least one feature of the input image and generating a model based on the at least one calculated feature. The method also includes the steps of repeating at least one of the previous steps for at least one other input image and comparing the at least one other input image with the model. The at least one other input image is classified in accordance with the class of the model if the at least one calculated feature of the at least one other input image is substantially similar to that of the model.
摘要翻译：对输入图像进行分类的方法包括根据类别对输入图像进行标记并从输入图像提取至少一个连接分量的初始步骤。该方法还包括以下步骤：计算输入图像的至少一个特征并基于至少一个计算的特征生成模型。该方法还包括以下步骤：对至少一个其他输入图像重复前述步骤中的至少一个，并将该至少一个其它输入图像与模型进行比较。如果所述至少一个其他输入图像的至少一个计算特征基本上类似于模型的特征，则至少一个其它输入图像根据模型的类被分类。

摘要： A computer-implemented method and system for reconstructing a clean document from annotated document images and/or extracting annotations therefrom are provided. The method includes receiving a set of at least two annotated document images into computer memory, selecting a representative image from the set of annotated document images, performing a global alignment on each of the set of annotated document images with respect to the selected representative image, and forming a consensus document image based at least on the aligned annotated document images. A clean document based at least on the consensus document image is then formed which can be used for extracting the annotations.
摘要翻译：提供了一种用于从注释的文档图像重建干净的文档和/或从其提取注释的计算机实现的方法和系统。该方法包括：将一组至少两个注释的文档图像接收到计算机存储器中，从所述一组注释文档图像中选择代表图像，对所选择的代表图像的所述一组注释文档图像中的每一个执行全局对齐，以及至少基于对齐的注释文档图像形成共识文档图像。然后形成至少基于共识文档图像的干净的文档，其可以用于提取注释。

摘要： Methods of generating image anchor templates from low variance regions of document images of a first class are provided. The methods select a document image from the document images of the first class and align the other document images of the first class to the selected document image. Low variance regions are then determined by comparing the aligned document images and the selected document image and used to generate image anchor templates.
