US Patent:

7167588, Jan 23, 2007
Filed:

Aug 9, 2002
Appl. No.:

10/215041
Inventors:

Daniel H. Greene - Sunnyvale CA, US
Justin Romberg - Houston TX, US
Ashok C. Popat - San Carlos CA, US
Assignee:

Xerox Corporation - Stamford CT
International Classification:

G06K 9/72
US Classification:

382229
Abstract:

Methods and systems for document image decoding incorporating a Stack algorithm improve document image decoding. The application of the Stack algorithm is iterated to improve decoding. A provisional weight is determined for a partial path to reduce template matching. In addition, semantically equivalent hypotheses are identified to reduce redundant hypotheses.

US Patent:

Filed:

Aug 9, 2018
Appl. No.:

16/059144
Inventors:

- Cambridge MA, US
- Atlanta GA, US
Ramesh Raskar - Cambridge MA, US
Alireza Aghasi - Chamblee GA, US
Justin Romberg - Decatur GA, US
International Classification:

G06K 9/46
G06K 9/20
G06K 9/00
Abstract:

A sensor may measure light reflecting from a multi-layered object at different times. A digital time-domain signal may encode the measurements. Peaks in the signal may be identified. Each identified peak may correspond to a layer in the object. For each identified peak, a short time window may be selected, such that the time window includes a time at which the identified peak occurs. A discrete Fourier transform of that window of the signal may be computed. A frequency frame may be computed for each frequency in a set of frequencies in the transform. Kurtosis for each frequency frame may be computed. A set of high kurtosis frequency frames may be averaged, on a pixel-by-pixel basis, to produce a frequency image. Text characters that are printed on a layer of the object may be recognized in the frequency image, even though the layer is occluded.
