摘要:
An integrated system and method for content-aware video retargeting. An interactive framework combines key frame-based constraint editing with numerous automatic algorithms for video analysis. This combination gives content producers a high level of control of the retargeting process. One component of the framework is a non-uniform, pixel-accurate warp to the target resolution that considers automatic as well as interactively-defined features. Automatic features comprise video saliency, edge preservation at the pixel resolution, and scene cut detection to enforce bilateral temporal coherence. Additional high level constraints can be added by the producer to achieve a consistent scene composition across arbitrary output formats. Advantageously, embodiments of the invention provide a better visual result for retargeted video when compared to using conventional techniques.

Techniques are provided for mesoscopic geometry modulation. A first set of mesoscopic details associated with an object is determined by applying a filter to an image of an object. Mesoscopic details included in the first set of mesoscopic details are detectable in the image of the object and are not detectable when generating a coarse geometry reconstruction of the object. A three-dimensional model for the object is generated by modulating the coarse geometry with the first set of mesoscopic details.

A fluorine-containing polymer segment includes at least one substituent for proton transfer that has one or more fluorine atoms. The fluorine-containing polymer segment is useful for forming hydrophilic polymer blocks that are used in block copolymers. Block copolymers useful for fuel cell applications incorporate the hydrophilic polymer blocks formed from the fluorine containing polymer segments.

摘要:
An image display apparatus includes a display layer and an image separation layer. The image separation layer is adapted to separate a displayed image on the display layer into a first image for a left eye of an observer and into a second image for a right eye of an observer. This renders the image display apparatus autostereoscopic. In order to improve the appearance of the displayed image, the apparatus is adapted to activate the display layer and the image separation layer substantially only within a given two-dimensional silhouette and to remain substantially transparent outside of the silhouette. In other aspects, the apparatus may be adapted to dynamically adjust an observation angle between the first image and the second image by controlling the distance between the display layer and the image separation layer by an actuator. The apparatus may be mounted on a robotic unit.

A drawing-tool renderer provides real-time rendering of lines with the look of artistic line drawings. A tip of a drawing tool (e.g., pencil) can be modeled as a constellation of points representing locations on the surface (or within the volume) of the tip. For a given point on a line being rendered, the location of the point and corresponding tool-tip parameters are used to determine which points in the tool tip model touch which portions of the paper. The effect of pigment transfer on cell color is modeled realistically. Various parameters of the model can be tuned to achieve a desired balance between rendering speed and accuracy of the simulation.

The invention relates to the actuation of an openable roof system, for example of a cabriolet canopy system, in which a synchronized adjusting phase (Ts) is provided during the adjustment (tθ to t3) for opening and/or closing the vehicle roof system, in which synchronized adjusting phase (Ts) a first hydraulic actuator and a second hydraulic actuator are hydraulically coupled for the synchronized movement (s1, s2) of two components of the vehicle roof system. In order to increase operational reliability, in particular to reduce the risk of undesired collisions of the components, the invention provides monitoring of the synchronized movement (s1, s2) of the two components during the synchronized adjusting phase (Ts), and in the event of a deviation of the synchronized movement (s1, s2) from a predefined nominal synchronized movement being detected, correction of the synchronized movement by at least partially suspending the hydraulic coupling of the two hydraulic actuators.

One embodiment of the invention contemplates a proton exchange membrane for use in a variety of fuel cells. The proton exchange membrane may comprise a solid phase organic based copolymer material in which a first structural unit is derived from a polymerizable organic super acid. The organic super acid may comprise an acid group such as a sulfonic acid group or a carboxylic acid group.
