Abstract: Super-resolution images may be produced by dividing a higher resolution image into a set of non-overlapping rectangular tiles of substantially the same size. Then, each pixel in each lower resolution image is mapped to the higher resolution image and it is determined which tiles are mapped to which lower resolution image pixels. A continuous buffer may be allocated for each tile and the relevant lower resolution pixels may be stored, together with optical flow vectors, in that continuous buffer. Then, the determination of gradients may use the information now stored in the buffer to facilitate symmetric multiprocessing using multi-core processors.

Abstract: A method of pattern and image recognition and identification includes building a data store of known patterns or images having known attributes and comparing those patterns to unknown patterns. The data store and comparison processing may be distributed across processors. A digital pattern recognition engine on each of the processors has the ability to compare a known pattern from the data store and an unknown pattern and compare the two patterns to determine whether the patterns constitute a match based on match criteria. If the comparison indicates a match, the match may be communicated to the data store and added as a known pattern with detected attributes to the data store. If the comparison does not indicate a match, the pattern may be flagged, transmitted to manual recognition, or further processed using character thresholding or cutting or slicing the pattern.

Abstract: An imaging system compensates for mask frame misalignment with non-mask frames in an image sequence of patient anatomy. The system includes an image data processor. The image data processor determines a compensation zoom factor for individual image frames of an image sequence of an object of interest in response to data indicating distance between the object and a radiation detector for the individual image frames. The processor then associates individual zoom factors with corresponding individual image frames of the image sequence. The individual zoom factors associated with corresponding individual image frames of the image sequence are stored in a repository. An individual determined zoom factor is applied to align an associated corresponding image frame with a mask frame to provide an aligned image frame. Data representing an image difference frame, comprising a difference between data representing the aligned image frame and a mask frame, is determined.

After that, when the resolution dependent processing is necessary to generate the vector data, the MFP 1 executes the resolution dependent processing in accordance with the determined processing resolution.

Abstract: This invention makes it possible to obtain an enlarged image while suppressing noise and maintaining the sharpness of an original image only by setting a simple enlargement ratio without no special knowledge. Original image data (Ia) is enlarged in accordance with a set enlargement ratio (E) to generate an enlarged image (IA). The enlarged image (IA) is smoothed by using a smoothing filter with a size depending on the enlargement ratio (E) to generate smoothed image data (IB). Difference image data (IC) is generated by calculating the difference between the enlarged image data (IA) and the smoothed image data (IB). The generated difference image data is multiplied by an emphasis coefficient. The product is added to the enlarged image data, thereby obtaining image data (IS) that has undergone enlargement/unsharp masking.

Abstract: Functionality for storing and modifying multi-resolution texture atlases is provided so that applications can expose methods to enable users to access and browse a collection that includes multiple multi-resolution images. The images are stored as thumbnails in a texture atlas having different levels of detail in which the levels are arranged in an image pyramid that includes multiple tiles that are each stored as separate files. The thumbnails are spatially storable as textures in the texture atlas using a fractal layout (which in one illustrative example is a Morton layout) that enables images to be efficiently packed in the tiles. The fractal layout ensures that no more than one tile stores less than a fully packed texture at each level of detail. The same packing order scales across each level of detail in the texture atlas so that layout information is stored for the individual images in the collection only once.

In the first pass, missing in-block pixels, which are the pixels within a block formed by four neighboring original pixels, are given values by gradient diffusion based upon interpolation of the surrounding original pixels. In the second interpolation pass, missing on-block pixels, which are the pixels on a block edge formed by two adjacent original pixels, are given values by gradient diffusion based upon interpolation of the values of those adjacent original pixels and the previously interpolated values of their adjacent in-block pixels. Also described is a difference projection process that varies the values of the interpolated pixels according to a computed difference projection.

The fast gradient solver may differentiate between the object and its background by applying artificial intelligence techniques and/or dependent on user-supplied hints.

Abstract: A method resizes input images by first constructing a grid graph. The grid graph includes one node for each pixel in the input image, and adjacent nodes in the grid graph are connected by arcs. Each arc is directed and has an associated cost. A cut is applied to the arcs of the grid graph using a cost function. A seam of pixels is determined from the cut so that coordinates of the pixels in the seam enforce monotonicity and connectivity constraints. Then, the input image is resized according to the seam to produce an output image while minimizing a change of energy in the output image when compared with the input image.

Abstract: Upon enabling an automatic cropping feature, a computer-implemented method for cropping a plurality of images retrieves a number of images to process among the plurality of images, and selects an image from the plurality of images to determine a set of crop values for the image until the set of crop values for each image have been determined. Determining a set of crop values for an image includes scanning the image from a first side to an opposing side to determine for each scan line of the image an amount representing a degree of color variation among the pixels for that scan line. The amount determined for each scan line is then compared to a threshold value until a crop value for a first area of the image can be determined.

The estimation calculation section calculates the difference between the light-receiving value of the pixel set at a first position and the light-receiving value of the pixel set at a second position, and estimates the estimated pixel values based on the difference.
