According to a first aspect of the present invention, currently persistent collaborative-writing-surface content may be imaged during periods of occlusion by an occluder. According to a second aspect of the present invention, the occluder may be imaged as transparent allowing the visibility of the occluded currently persistent collaborative-writing-surface content. According to a third aspect of the present invention, the occluder may be imaged as a silhouette allowing visibility of the occluded currently persistent collaborative-writing-surface content. | 03-15-2012 |
20120224783 | Methods and Systems for Document-Image Correction - Aspects of the present invention are related to systems and methods for correcting illumination and vignette in a camera-captured document image. A background type may be detected from down-sampled luminance image associated with the camera-captured image, and model parameters may be estimated for a morphologically filtered version of the down-sampled luminance image, wherein the morphological filter may be based on the detected background type. The model parameters may be verified and if deemed acceptable, a rectified image may be formed. | 09-06-2012 |
20120249554 | Methods and Systems for Mobile Document Acquisition and Enhancement - Aspects of the present invention are related to systems and methods for correcting artifacts in a camera-captured image of a document or image of an object exhibiting document-like content. A mobile device may capture an image and send the image to a cloud computing system for processing. According to a first aspect of the present invention, the mobile device may provide real-time feedback cues to assist in the capture of an image. The mobile device may detect a region-of-interest in the captured image, and a user may refine or confirm the detected region-of-interest. The captured image, information identifying the region-of-interest and a metadata tag, referred to as a region-of-interest modification tag, indicating whether, or not, the region-of-interest was refined by a user may be sent to the cloud. The cloud may process the image giving priority to the region-of-interest received from the handset when the region-of-interest modification tag indicates that the region-of-interest was refined by a user over a cloud determined region-of-interest. The cloud may transmit, to the handset, the processing results. | 10-04-2012 |
