Abstract: A process for preparing low melting copolymers comprising contacting a mixture of olefin monomers with a CpFlu-type metallocene catalyst under reaction conditions sufficient to form a copolymer. The copolymers thus prepared desirably display melt temperatures from about 100° C. to about 140° C. and may be produced with reduced amounts of ethylene. The copolymers may also exhibit reduced levels of undesirable xylene solubles, relatively narrow molecular weight distribution, and other improved optical and physical properties.

Abstract: The tendency of copolymer fluff grains of propylene and ethylene to agglomerate is reduced by injecting at least one olefin comonomer, such as ethylene monomer, into more than one point along the length of the reactor, rather than injecting all of the ethylene at one point. This process reduces the tendency of copolymer fluff grains to agglomerate and cause processing problems as compared with injecting the comonomer at only one point. Copolymer made by this process is expected to have lower substantially amorphous polypropylene content and better organoleptics than copolymer made where the ethylene is injected at only one point. In one non-limiting embodiment the copolymerization reactor is a loop-type reactor.

Abstract translation: 通过将至少一种烯烃共聚单体如乙烯单体注入到沿反应器长度的多于一个点中，而不是在一点注入所有乙烯，丙烯和乙烯的共聚物绒毛颗粒聚集的趋势被减少。 与仅在一点注入共聚单体相比，该方法降低共聚物绒毛颗粒凝聚的倾向并引起加工问题。 通过该方法制备的共聚物预期与仅在一点注入乙烯的共聚物相比具有较低的基本无定形聚丙烯含量和更好的感官。 在一个非限制性实施方案中，共聚反应器是环型反应器。

Abstract: In accordance with an embodiment, a method of authenticating images includes electronically receiving an anchor image and a query image, performing a feature point extraction of an anchor image, and performing a feature point extraction of a query image. The method also includes clustering feature points of the anchor image and feature points of the query image, where clustering includes determining matching feature points, determining outlier feature points, and excluding outlier feature points. Whether the anchor image is similar to the query image is determined based on a distance between the feature points of the anchor image and the feature points of the query image. If the anchor image is similar to the query image, possible tampered areas of the query image based on the outlier feature points are identified.

Abstract: An image processing method can be performed on a video image that includes an initial frame and a plurality of subsequent frames. An object is located within the initial frame of the video image and a histogram related to the object is generated. A foreground map that includes the object is also generated. For each subsequent frame, a mean shift iteration is performed to adjust the location of the object within the current frame. The histogram related to the object and the foreground map can then be updated.
