Abstract: A method for data processing (250) includes transforming measurement data acquired in the time domain during an oilfield operation into a second domain to produce transformed data (251); identifying distortions in the transformed data (252); removing the distortions from the transformed data (252); and transforming back from the second domain to the time domain to produce cleaned-up data. The transforming measurement data may use a Fourier transform or a wavelet transform. The method may further include compressing the cleaned-up data (253) or reconstructing signals from the cleaned-up data (254). A method for data processing includes decomposing measurement data, which are acquired in an oilfield operation, using a low pass filter to produce a first dataset; decomposing the measurement data using a high pass filter to produce a second dataset; removing distortions from the second' dataset to yield a corrected second dataset; and reconstructing a corrected dataset from the first dataset and the corrected second dataset.

Abstract: A system and method for extracting depth information from at least two images employing region-based filtering for reducing artifacts are provided. The present disclosure provides a post-processing algorithm or function for reducing the artifacts generated by scanline Dynamic Programming (DP) or other similar methods. The system and method provides for acquiring a first image and a second image from a scene (202), estimating the disparity of at least one point in the first image with at least one corresponding point in the second image to generate a disparity map (204), segmenting at least one of the first or second images into at least one region (208), and filtering the disparity map based on the segmented regions (210). Furthermore, anisotropic filters are employed, which have a great smoothing effect along the vertical direction than that of the horizontal direction, and therefore, reduce stripe artifacts without significantly blurring the depth boundaries.

Abstract: The present invention relates to a transport container which provides mechanical and thermal stability for a load and which container is fabricated as the container is loaded. In particular, the present invention relates to a container which can be readily transported on aircraft, such as an aircraft container. In the field of logistics, that is the field of movement and supply of produce and materials, in particular in the transport of intermediate and finished products, containers have been developed which safely protect from physical damage a wide variety of product. Food and pharmaceutical products not only need protection from physical shock and pressures but also require temperature stability during transportation; otherwise goods can be damaged and be unusable, whether such damage is apparent or not. However, air transport poses a particular problem: Goods can be transported in tropical heat, packaged and placed upon pallets and the like containers whereby they are presented in aircraft style containers. Such goods may be left on runways at extreme temperatures (+40° C) and then placed within a hold where low pressures and low temperatures exist during flight. At a destination airport the temperatures may well be sub-zero. To simplify transport with respect to airports, planes and handling equipment, there have been developed aircraft Unit Load Devices (ULDs) which comprise any type of pallet or container that can easily be loaded to the aircraft by a ground handler. The present invention seeks to provide a transport container which can maintain goods within a narrow temperature range, can displace a considerably reduced volume before erection, is economical to manufacture, can readily and easily be constructed. The present invention further seeks to provide a transport container which is compatible with standard Unit Load Device specifications.
