摘要:
The invention relates to a method for identifying a character that has a character contour formed by gray value curves, having the steps of determining (101) a plurality of gray value gradients using the gray value curves, determining (103) a first number of gray value gradients of the plurality of gray value gradients, said gray value gradients running within a first angular range with respect to a first direction, determining (105) a second number of gray value gradients of the plurality of gray value gradients, said gray value gradients running within a second angular range with respect to a second direction, and identifying (107) the character using a relation between the first number of gray value gradients and the second number of gray value gradients.
摘要:
An analyzing unit has a linear SVM discriminating section and a nonlinear SVM discriminating section and analyzes an image data having an intensity data for numerous wavelengths in each pixel. In the linear SVM discriminating section, the discrimination as to whether the intensity data is an object data or not is performed for every pixel by using an intensity data of the image data as a feature quantity and using the linear SVM, and subsequently in the nonlinear SVM discriminating section, discrimination using the nonlinear SVM is performed only with respect to the pixels discriminated by the linear SVM as their intensity data being object data. Discrimination can be accomplished with higher precision as compared with the case where all pixels are discriminated only with the linear SVM. Also, as compared with the case where the discrimination is conducted only with the nonlinear SVM for all pixels, the discrimination can be accomplished at higher speed.

Subregions of a document image are clustered. A replica image of the document is created by replacing sub-regions in the document image with a representative cluster image generated for the cluster in which the respective sub-regions are included. This allows to obtain a higher resolution image.

A system for processing text captured from rendered documents is described. The system receives a sequence of one or more words optically or acoustically captured from a rendered document by a user. The system identifies among words of the sequence a word with which an action has been associated. The system then performs the associated action with respect to the user.

A biometric authentication engine is described. The engine includes components which are configured to authenticate a user based on one or more presented biometrics. The system makes use of multiple threshold parameters or scores so that the authentication process is better tailored to match the specifics of the authentication request.
