Abstract: A system and method for modifying images has an ability to assign color intensity values to pixels exposed during image manipulation operations. The system and method for modifying images comprises means for using the color intensity values of remaining pixels in the original image, and for assigning color values to the exposed pixels that are similar to those of the surrounding pixels so that the exposed regions blends smoothly with the surrounding region. The means for assigning color values assigns the value of color intensity based on the color intensity value function determined at a location of a pixel. The color intensity value function used to assign values to exposed pixels is determined by fitting a function to the known color intensity values of pixels in the boundary regions of the exposed surrounding pixels. The color intensity value function is approximated using energy minimization along with boundary conditions.

Abstract: A method and apparatus for transferring data between a handheld device and a network over a wireless communications link. A datapool manager breaks files into virtual blocks and adds the virtual blocks to a datapool. A communications manager converts the virtual blocks into transportation packets and controls the transfer of the transportation packets between the handheld device and the network. After a transportation packet is transferred, an acknowledgment is returned indicating that the transfer was successful. If the transfer of a file is interrupted, then, upon reestablishing the wireless link, only those transportation packets for which an acknowledgment has not been returned are transferred. To properly reconstruct the file, a pointer indicates the location of each transportation packet in the file. Furthermore, to enable the use of a partially transferred file, a table of information is maintained indicating the validity of the partially transferred file. Transportation packets are identified as instruction packets or data packets. When determining the order of transfer, priority is placed on the transfer of instruction packets.

Abstract: Techniques for generating a gradient characterization for a first fingerprint image are provided. One or more fingerprint feature points are selected from the first fingerprint image. A region is obtained for each of the one or more selected fingerprint feature points. The region is a representation of an area proximate a given fingerprint feature point. Each of the obtained regions is divided into a plurality of sub-regions. A histogram is generated for each of the plurality of sub-regions. For each of the one or more selected fingerprint feature points, the one or more generated histograms are combined into a concatenated histogram. The concatenated histogram is used for identification purposes.

Abstract: A system, method, and apparatus for reducing the video decoder processing requirements for rewinding a HITS stream are presented herein. During rewind of a HITS stream, the video decoder builds a clean reference picture. The clean reference picture is built by decoding each of the P-pictures in the EP-EP segment. However, because the P-pictures are not displayed, the decoder does not decode the portion of the P-picture below the last intracoded slice. The decoder can build the clean reference picture without decoding the portions of the P-pictures below the last intracoded slice because the subsequent pictures do not use the said portions for prediction.

Abstract translation: 本文给出了一种用于降低用于重绕HITS流的视频解码器处理要求的系统，方法和装置。 在HITS流的倒带期间，视频解码器构建干净的参考图片。 通过对EP-EP段中的每个P图像进行解码来构建干净的参考图像。 然而，由于不显示P图像，所以解码器不会在最后一个内部编码的切片之下对P图像的部分进行解码。 解码器可以构建干净的参考图像而不对最后一个内部编码的切片之下的P图像的部分进行解码，因为后续图像不使用所述部分进行预测。

Abstract: A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.

Abstract: Searching online catalog databases by shoppers is improved by performing similarity searching on searches performed by the shopper, in conjunction with adjusting the similarity metric used during the search to interactively improve the relevance of the resulting search results to the shopper. This involves using relevance feedback and/or product redefinition to learn the “implied concept” of the shopper's stated product requirements; that is, the quality of the search results is enhanced through understanding the concept implied by the shopper's queries by, for example, learning from the product results marked as “relevant” or “irrelevant” by the shopper. This approach is in contrast with attempts to enhance search results using, for example, the shopper's past orders or previous actions, or the past orders or previous actions of other shoppers who may have a purchase history similar to that of the current shopper.

Abstract translation: 通过对购物者执行的搜索执行相似性搜索，结合调整搜索期间使用的相似性度量来交互地提高所得到的搜索结果与购物者的相关性，从而改善了购物者对在线目录数据库的搜索。 这涉及使用相关性反馈和/或产品重新定义来了解购物者声明的产品要求的“隐含概念”; 也就是说，通过了解购物者查询所隐含的概念，例如从购物者标识为“相关”或“无关”的产品结果中学习，可以提高搜索结果的质量。 这种方法与使用例如购物者的过去订单或先前操作或其他可能具有与当前购物者的购买历史相似的购买历史的其他购物者的过去订单或之前的动作来增强搜索结果形成对比。
