Abstract: A method for reversing gelation of hydrophobically modified biopolymer attached to vesicle or cell membranes. The gelation of hydrophobically modified biopolymer attached to vesicles or cell membranes is reversed by application of a supramolecule, such as cyclodextrin, to the gelled composition. The supramolecule disrupts the interactions between the hydrophobically modified biopolymer and the vesicle or cell membrane, without affecting the structure of the membrane or the hydrophobically modified polymer to which the hydrophobic substituents are attached. A kit for treating wounds that includes a hydrophobically modified biopolymer and a supramolecule. The hydrophobically modified biopolymer is used to stop bleeding and the supramolecule is used to remove the hydrophobically modified biopolymer.

Abstract: The present invention is a system and a method for processing stereo images utilizing a real time, robust, and accurate stereo matching system and method based on a coarse-to-fine architecture. At each image pyramid level, non-centered windows for matching and adaptive upsampling of coarse-level disparities are performed to generate estimated disparity maps using the ACTF approach. In order to minimize propagation of disparity errors from coarser to finer levels, the present invention performs an iterative optimization, at each level, that minimizes a cost function to generate smooth disparity maps with crisp occlusion boundaries.
