20090185078 | SYSTEMS AND METHODS FOR VIDEO PROCESSING BASED ON MOTION-ALIGNED SPATIO-TEMPORAL STEERING KERNEL REGRESSION - A method for video processing based on motion-aligned spatio-temporal steering kernel regression may include estimating local spatio-temporal steering parameters at pixels in input video data. The method may also include using the local spatio-temporal steering parameters to apply motion-aligned spatio-temporal steering kernel regression to the input video data to perform at least one of upscaling and noise smoothing. | 07-23-2009 |

20110043706 | Methods and Systems for Motion Estimation in a Video Sequence - Aspects of the present invention are related to systems and methods for determining local-analysis-window size and weighting parameters in a gradient-based motion estimation system. | 02-24-2011 |
20110058610 | Methods and Systems for Motion Estimation with Nonlinear Motion-Field Smoothing - Aspects of the present invention are related to low complexity systems and methods for nonlinear diffusion filtering of a motion-vector field. Local weights in the nonlinear diffusion filter may be data-adaptive, and, according to one aspect of the present invention, may be determined such that spatial coherency may not be enforced at object boundaries although the object boundaries have not been explicitly detected. Thus, the methods and systems of the present invention may smooth a motion-vector field without smoothing the motion-vector field across an object boundary. According to a second aspect of the present invention, motion vectors with a low confidence value may be suppressed, while motion vectors with a high confidence value may be propagated. According to another aspect of the present invention, motion estimation methods and systems may incorporate the methods and systems of the nonlinear diffusion filtering according to the present invention. | 03-10-2011 |
20120075506 | NOISE REDUCTION FOR MACHINE VISION SYSTEMS - A method for reducing noise in an image from an image capture device includes filter the image using both an offset fixed pattern noise filter and a gain fixed pattern noise filter. Thereafter, the image is filtered using a remnant fixed pattern noise filter to reduce remnant fixed pattern noise. | 03-29-2012 |
20130170767 | IMAGE CONTENT ENHANCEMENT USING A DICTIONARY TECHNIQUE - A system for determining a high resolution image includes receiving a low resolution image and determining a vector of a patch of the low resolution image based upon a low resolution dictionary. The system includes determining a high resolution patch based upon a high resolution dictionary and the vector and determining the high resolution image based upon the high resolution patch. | 07-04-2013 |
