In this paper a segmented video codec with hybrid motion estimation and inherent bit rate control capability is presented. The first frame in the data is always encoded in intraframe mode, while the rest of the frames are encoded in interframe mode. The interframe encoding is based on (1) hybrid conventional/perspective block motion vector estimation and coding, and (2) coding of the prediction...

In this paper, we present a technique that combines motion planning and part interaction clusters to improve generation of assembly precedence constraints. In particular, this technique automatically finds, and clusters, parts that can mutually affect each other’s accessibility, and hence may impose assembly constraints. This enables generation of accurate precedence constraints without needing...

Based on the accelerator theory and virtual prototyping technique, an accelerator virtual prototyping system (AVPS) is formulated, implemented for the innovative design of low energy accelerators. The framework of AVPS takes into account the needs of manufacture, assembly/disassembly, operation, and maintenance in a virtual environment during the design phase. In order to guarantee the reliabil...

INTRODUCTION In plaque psoriasis, the benefit of topical steroids is well established. The vehicle formulation of topical steroids may also provide benefit in addition to the effects of the steroid itself. DFD-01 (betamethasone dipropionate spray, 0.05%) is a formulation composed of a topical steroid in an emollient-like vehicle that enhances penetration to the target site of inflammation in th...

In this paper, we propose a new scheme for position coding of the atoms within the Matching Pursuit algorithm as applied to the displaced frame difference (DFD) in a hybrid video encoder. We exploit the spatial and temporal coherence of the positions of the atoms in the DFD: the atoms tend to cluster in regions where the motion prediction fails. The location of these regions is correlated over ...

Previously published experiments have shown that the endogenous Dfd gene can be ectopically activated by its own (heat-shock-driven) product in a subset of cells of different segments. This results in the differentiation of maxillary structures like cirri and mouth hooks in places where they normally do not appear, and represents a phenomenon of autocatalysis of homeotic gene function that diff...

Depth From Defocus (DFD) is a depth recovery method that needs only two defocused images recorded with different camera settings. In practice, this technique is found to have good accuracy for cameras operating in Normal Mode. In this paper, we present new algorithms to extend the DFD method to cameras working in Macro Mode used for very close objects in a distance range of 5 cm to 20 cm. We ad...
