20100021084RESOLUTION ENHANCEMENT OF VIDEO SEQUENCES WITH ARBITRARY ENHANCEMENT FACTOR - Restoration based super-resolution combines a video sequence of low-resolution noisy blurred images using maximum likelihood estimation without regularization to produce a higher resolution image or video sequence up to a maximum enhancement factor r for the given video sequence.

20120269458Method for Generating High Resolution Depth Images from Low Resolution Depth Images Using Edge Layers - A method interpolates and filters a depth image with reduced resolution to recover a high resolution depth image using edge information, wherein each depth image includes an array of pixels at locations and wherein each pixel has a depth. The reduced depth image is first up-sampled, interpolating the missing positions by repeating the nearest-neighboring depth value. Next, a moving window is applied to the pixels in the up-sampled depth image. The window covers a set of pixels centred at each pixel. The pixels covered by the window are selected according to their relative offset to the depth edge, and only pixels that are within the same side of the depth edge of the centre pixel are used for the filtering procedure.10-25-2012

One embodiment includes determining a scaling resolution based on a pixel resolution of the image and a pixel resolution of an output device (i.e., factors of the scaling resolution). The image is converted to the scaling resolution to change (e.g., increase) the pixels of the image by the first factor. A grid is generated to scale the converted image. The grid has a number of sections defined according to the second factor times the pixel resolution of an output device. The converted image is sectioned according to the grid. Each section of the grid includes an integer number of pixels of the converted image. The color values of the pixels of the converted image are averaged within each section of the grid to compute a single color value for each section of the grid and scale the image.09-29-2011

During dimensional conversion of a slide, foreground objects placed on the slide by a user are dimensionally scaled and repositioned on the slide based on a change in the overall dimensions of the slide, while background objects on the slide originating from a slide master associated with the slide are replaced with corresponding background objects from a new template associated with the new aspect ratio of the slide. Any content and/or properties of the old background objects on the slide are copied to the corresponding background objects on the dimensionally converted slide.08-01-2013
