20080226193 | MOTION ESTIMATION APPARATUS AND METHOD - An estimation unit calculates an estimated motion vector between a first source region of a plurality of source regions and a first destination region on a destination picture. The first destination region has the highest correlation with the first source region. A weight calculation unit searches a plurality of second destination regions. Each second destination region is pointed by the estimated motion vector of another source region adjacent to the first source region. The weight calculation unit extracts pixel values of each second destination region, calculates a difference of pixel values between the first source region and each second destination region, and calculates a weight based on the difference. The weight is smaller if the difference is larger. A filtering unit calculates a motion vector of the first source region by averaging the estimated motion vectors with the weight. | 09-18-2008 |

20090016641 | Method and apparatus for efficient client-server visualization of multi-dimensional data - In response to a request from a client, a server for volume rendering loads a volume dataset from a storage archive, creates a low resolution sub-sampled copy of such volume dataset and transmits it to a client.

20090016642 | METHOD AND SYSTEM FOR HIGH RESOLUTION, ULTRA FAST 3-D IMAGING - A high-speed three-dimensional imaging system includes a single lens camera subsystem with an active imaging element and CCD element, and a correlation processing subsystem. The active imaging element can be a rotating aperture which allows adjustable non-equilateral spacing between defocused images to achieve greater depth of field and higher sub-pixel displacement accuracy. A speckle pattern is projected onto an object and images of the resulting pattern are acquired from multiple angles. The images are locally cross-correlated using a sparse array image correlation technique and the surface is resolved by using relative camera position information to calculate the three-dimensional coordinates of each locally correlated region. Increased resolution and accuracy are provided by recursively correlating the images down to the level of individual points of light and using the Gaussian nature of the projected speckle pattern to determine subpixel displacement between images. Processing is done at very high-speeds by compressing the images before they are correlated. Correlation errors are eliminated during processing by a technique based on the multiplication of correlation table elements from one or more adjacent regions. | 01-15-2009 |
