摘要： A video is resized while preserving salient regions within the video. The dimensions of the video are reduced by selectively removing unimportant, or less salient, pixels from the video in a manner that diminishes any resulting spatial and temporal artifacts. More specifically, “seams” of pixels are selectively removed from frames of the video, where a “seam” is a horizontal or vertical chain of pixels through a frame. A seam can be selected from among all possible pixels in a row or column, thereby allowing discontinuous seams. Seams are selected using a technique that encourages the seam to pass through less-salient regions of the frame, and that reduces spatial artifacts when the video is played.

摘要： A method for measuring the conducting fluid saturation and the resistivity of a porous medium have application to development of underground geological formations. A solid sample is extracted from the medium and placed in a centrifugation cell, beside a second sample for limiting the capillary end effect in the first sample. The two samples are partly desaturated by subjecting them to centrifugation. The resistivity of the sample is measured by placing it in a radial-electrode resistivity measurement cell. The saturation of the sample is then determined by measuring its nuclear magnetization by means of an NMR device. Repeating this procedure for different centrifugation velocities provides resistivity and saturation pairs allowing a relationship between saturation and resistivity to be estimated.

摘要： A fully automatic, computationally efficient segmentation method of video employing sequential clustering of sparse image features. Both edge and corner features of a video scene are employed to capture an outline of foreground objects and the feature clustering is built on motion models which work on any type of object and moving/static camera in which two motion layers are assumed due to camera and/or foreground and the depth difference between the foreground and background. Sequential linear regression is applied to the sequences and the instantaneous replacements of image features in order to compute affine motion parameters for foreground and background layers and consider temporal smoothness simultaneously. The Foreground layer is then extracted based upon sparse feature clustering which is time efficient and refined incrementally using Kalman filtering.

摘要： An interactive system and process for constructing a model of a 3D scene from a panoramic view of the scene. In the constructed model, the 3D scene is represented by sets of connected planes. The modeling begins by providing the user with a display of an image of the panoramic view. The user is then required to specify information concerning certain geometric features of the scene. A computer program recovers a camera orientation matrix of the panoramic view based on the features specified by the user. Plane normals and line directions for planes in the 3D scene are estimated using this matrix as well as the user-specified information. A camera translation is also recovered, as are plane distances and vertex point locations for planes in the 3D scene, using the user-supplied information, camera orientation matrix, and the estimated plane normals and line directions. The model of the 3D scene is then constructed based on the plane normal and plane distance, and/or the vertex point locations, of each plane in the set. Preferably, the plane distances and vertex point locations, and optionally the camera translation, are recovered by creating a system of equations based on the geometric constraints of the 3D scene. The constraint equation are characterized as hard is they include a user-designated parameter, otherwise they are considered soft constraints. The systems of equations is solved in a manner which gives priority to hard constraint equations. A decomposing process can also be employed prior to solving the systems of equation to ensure their solvability.
