| 20090257682 | SYSTEM AND METHOD FOR AUTOMATIC DIGITAL IMAGE ORIENTATION DETECTION - Described is a system for automatic digital photo orientation detection. We leverage online public photos with great content variation to extract effective features with layout information. Classification proceeds using an approximate nearest neighbors approach which scales well to massive training sets, hardly compromising efficiency. We have tested the method successfully on the largest data set to date of nearly 30,000 Flickr photos as well as both difficult and typical consumer usage scenarios. Though limited data are available for comparison across different systems, the proposed system significantly outperforms a state of the art system on a common data set. | 10-15-2009 |
| 20090274392 | PAGE ORIENTATION DETECTION BASED ON SELECTIVE CHARACTER RECOGNITION - A system and method for character recognition with document orientation determination is shown. The method is a detection of simple page orientation based on a limited version of character recognition. The method includes binairizing an input image which has a plurality of alphanumeric characters with a first orientation. The method continues with extracting the connected components and determining a second orientation where the second orientation is based on a 90° turn clockwise or counterclockwise or, in the alternative, no turn from the first orientation. The second orientation will result in a 180° variance from the proper orientation or it will be the proper orientation. The method continues with implementing a limited version of optical character recognition for an analysis of a character and determining if that second orientation is upside down, based at least in part on the analysis. This method generally uses the character “i” for analysis. However, for documents that have a limited number of “i”s, e.g. such as Russian documents or documents with all capital letters, the “T” may also be used. | 11-05-2009 |
