Fraud detection via automated handwriting clustering

A computer-implemented method for automatically analyzing handwritten text to determine a mismatch between a purported writer and an actual writer is disclosed. The method comprises receiving two samples of digitized handwriting each allegedly created by one individual and received and entered into a digital system by another. The method further comprises performing a series of feature extractions to convert the samples into two vectors of extracted features; automatically clustering a set of vectors such that the first vector and the second vector are assigned to the same cluster among multiple clusters, based on vector similarity; and automatically determining that a same individual being associated with both the first and second samples indicates a heightened probability that the individual fraudulently created both samples. Finally, the method comprises automatically transmitting a message to flag additional samples of digitized handwriting entered into a digital system as possibly fraudulent.

Method and system for training neural network for entity detection

A system and method for training a neural network is implemented for detecting at least one entity in a document to derive relevant inferences therefrom. The method describes obtaining at least one document. The at least one document is processed, via a detection module, to detect a widget entity. The detected widget entity is classified as active or inactive based on a detected state of the widget entity. The classified widget entity is modified into a corresponding machine-readable widget-entity based on the detected state. The at least one document is processed, via an extraction module, to detect a text entity in near vicinity of the classified widget entity. A training pair comprising the machine-readable widget entity and the corresponding text entity is generated. The neural network is trained using the generated training pair.

LAYOUT RECONSTRUCTION USING SPATIAL AND GRAMMATICAL CONSTRAINTS

During an image-analysis technique, the system calculates features by performing image analysis (such as optical character recognition) on a received image of a document. Using these features, as well as spatial and grammatical constraints, the system determines a layout of the document. For example, the layout may be determined using constraint-based optimization based on the spatial and the grammatical constraints. Note that the layout specifies locations of content in the document, and may be used to subsequently extract the content from the image and/or to allow a user to provide feedback on the extracted content by presenting the extracted content to the user in a context (i.e., the determined layout) that is familiar to the user.

20190005323 · 2019-01-03 ·

An apparatus obtains first transformation information, such as a first transformation matrix, to be used for coordinate transformation between a coordinate system in an overall image prepared beforehand and a coordinate system in a first captured image, by comparing a feature point extracted from the overall image and a feature point extracted from the first captured image. In a case where the first transformation information is updated, the apparatus generates a partial image from the overall image based on an image-taking position of a just preceding image, and compares a feature point extracted from the partial image with a feature point extracted from a captured image to be used for updating of the first transformation information, and accordingly obtains transformation information for updating. The apparatus updates the first transformation information by using the obtained transformation information for updating. Thus, accuracy of tracking processing is improved.
