Abstract: Systems, methods, and computer readable media expounding “Structure Histograms” and their use are presented. Structure Histograms may be described as histograms whose individual entries (values) express a functional relationship between a given pixel (or group of pixels) and its neighboring pixels. As such, Structure Histograms capture information about the structure of an image in so far as they record information related to the relative placement of pixels within an image (e.g., are pixels of a common value closely spaced or spaced far apart). Structure Histograms may be generated from tonal pixel values (e.g., red, green and blue values), luminance pixel values (e.g., gray scale pixel values) or cross-channel pixel values (e.g., red-luminance, green-blue, or green-blue-luminance pixel values). Structure Histograms may be used in a number of image processing contexts such as, for example, automated image enhancement operations.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for color-space selective darkness and lightness improvements. In one aspect, a method accessing multiple pixels that represent a digital image in an RGB color space. The accessed pixels are processed based on a darkness of the digital image resulting in a first set of processed pixels, and separately based on a lightness of the digital image resulting in a second set of processed pixels. Both sets of processed pixels are combined to generate a processed output image.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for applying color balancing to at least a portion of a digital image based on the digital image content. The color balancing process preferably operates in a gamma modified color space, transformed into an opponent color space with separate luminance and chromatic channels. The method also includes identifying a difference of at least one of the chromatic channels between an average color, determined for a region of interest in the digital image, and an ideal reference color for the feature the user desires to correct, as a basis for the color balancing process.

Abstract: A method of indexing information stored on a portable electronic device. The method includes receiving an association signal by the portable electronic device the association signal providing an indication of adjacent resources, accessing a database including a table storing relationships between data stored on the portable electronic device and the association signal, and indexing the data based on the relationships accessed in the database.

Abstract: A computer implemented method for a touch screen user interface for a computer system. A first touchscreen area is provided for accepting text input strokes. A second touchscreen area is provided for displaying recognized text from the text input strokes. The text input strokes are displayed in the first touchscreen area. The text input strokes are recognized and the resulting recognized text is displayed in the second touchscreen area. A portion of the recognized text is displayed in the first touchscreen area, wherein the portion of the recognized text is shown as the text input strokes are recognized.

A portion of the recognized text is displayed in the first touchscreen area, wherein the portion of the recognized text is shown as the text input strokes are recognized. The portion of the recognized text displayed scrolls as the new text input strokes are recognized. The portion of the recognized text in the first touchscreen area can be displayed in a different format with respect to the recognized text in the second touchscreen area.

Abstract: A system and method for changing data displayed on a touch-sensitive display screen. The present system and method recognize handwritten strokes made with a stylus on the touch-sensitive display screen of a PDA or palmtop computer in order to alter or correct displayed data. In one mode of operation, computer controlled association of the location of the handwritten strokes on the display screen with one or more of the displayed characters will result in automatic replacement of those characters by the handwritten strokes. In a second mode of operation, matching at least one of the handwritten strokes with one character of the displayed data will result in replacement of one or more characters of the displayed data with the handwritten characters. With the present system and method, the number of steps required to alter displayed data is reduced to the number of handwritten strokes. A significant reduction in time and effort as well as a simplification in application is therefore offered.

Abstract: An isolation process which enhances the performance of silicon micromechanical devices incorporates dielectric isolation segments within the silicon microstructure, which is otherwise composed of an interconnected grid of cantilevered beams. A metal layer on top of the beams provides interconnects and also allows contact to the silicon beams, electrically activating the device for motion or transduction. Multiple conduction paths are incorporated through a metal patterning step prior to structure definition. The invention improves manufacturability of previous processes by performing all lithographic patterning steps on flat topographies, and removing complicated metal sputtering steps required of most high aspect ratio processes. With little modification, the invention can be implemented with in grated circuit fabrication sequences for fully integrated devices.
