Abstract: A system and method for synthesizing painterly-looking images from input images (e.g., photographs). An input image is first interactively decomposed into a hierarchical representation of its constituent components named parse tree, whose nodes correspond to regions, curves, and objects in the image, with occlusion relations. According to semantic information in the parse tree, a sequence of brush strokes is automatically prepared according a brush dictionary manually built in advance, with their parameters in geometry and appearance appropriately tuned, and blended onto the canvas to generate a painterly-looking image.

Abstract: In an imaging mass analysis, image information of a sample allows users to grasp specific information about the sample, such as distribution of a portion with a particular function or effect. The mass spectrum intensity data are normalized for each pixel so that the sum of the intensities over the entire mass-to-charge ratio (m/z) is one. Entropy is calculated by totaling the product of the intensity normalizing at each m/z and the logarithm of that intensity over the entire m/z range. After the entropy is calculated for each pixel, the pixels are colored according to their entropy values to display a two-dimensional color image of entropy distribution. The entropy of a cancerous portion is relatively small because of a high content of a specific kind of substance and the simplified composition of the substances. Thus, the cancerous part and the normal part of the entropy image can be distinguished.

Motion commands are generated for the reduced set of motion hints and applied to a copy of the current frame at the server. Differences between the modified current frame and the new frame are then encoded as delta commands. The server then sends the motion commands and delta commands to the client. The client receives and applies the commands to the current frame to render the new frame.

Abstract: User input interpretation mechanisms can pass along user input without delay by initially treating it as freeform movement and passing it along unmodified, rather than waiting to receive a sufficient quantity of user input from which to derive a user's intentions. User input within a defined range from an initial point is freeform movement, passed along unmodified, while user input beyond that range can be confined to a groove if it evidences an intention to move in a precisely linear manner. Grooves can be established to aid in precise vertical movement, with no horizontal deviations, precise horizontal movement, with no vertical deviations, or any other orientation. Before being passed along, user input in groove regions can be modified to center the input within the groove region and eliminate human inaccuracies, such as slight deviations to either side. User input can escape groove regions by moving orthogonally to them.
