Patent number: 8478057Abstract: Compression of an image is performed based on prediction of target blocks of an image from candidate source blocks of the image. Heuristics are used for identifying the candidate source blocks, for example, source blocks are selected from within a cluster of similar blocks obtained by K-means clustering. For each target block, a region adjacent to the target block is identified and a set of candidate source blocks along with candidate source regions adjacent to the candidate source blocks are identified. The candidate source regions are ranked based on the differences between the candidate source regions and the target source region. Each candidate source block is described using its rank and residual information describing differences between the candidate source block and the target block. The candidate source block that can be described using a minimum amount of information is selected for predicting the target block.Type: GrantFiled: January 22, 2010Date of Patent: July 2, 2013Assignee: Google Inc.Inventors: Jingyu Cui, Vivek Kwatra, Michele Covell, Mei Han, Saurabh Mathur

Patent number: 8178587Abstract: The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises at least 50 vol. % of the extracted gas. The extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst at a temperature of less than 600° C. to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid hydrocarbon or a liquid hydrocarbon oxygenate.Type: GrantFiled: May 13, 2009Date of Patent: May 15, 2012Assignee: Shell Oil CompanyInventors: Mahendra Ladharam Joshi, Jingyu Cui, Frederik Arnold Buehrman, Scott Lee Wellington

Patent number: 8138381Abstract: The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises greater than 40 vol. % of the extracted gas. The extracted gas is scrubbed with a wash effective to produce a washed extracted gas containing less carbon dioxide than the extracted gas and at least 20 vol. % carbon dioxide. The washed extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid methanol product.Type: GrantFiled: January 5, 2010Date of Patent: March 20, 2012Assignee: Shell Oil CompanyInventors: Mahendra Ladharam Joshi, Jingyu Cui, Frederik Arnold Buhrman, Scott Lee Wellington, Stanley Nemec Milam, Rogier Maarten Kamerbeek
