Abstract: A sprite generation method used in video coding generates a sprite from the video objects in the frames of a video sequence. The method estimates the motion (1200) between a video object in a current frame and a sprite constructed from video objects for previous frames. Specifically, the method computes motion coefficients of a 2D transform that minimizes the intensity errors between pixels in the video object and corresponding pixels inside the sprite. The method uses the motion coefficients from the previous frame (1206) as a starting point to minimizing the intensity errors. After estimating the motion parameters for an object in the current frame, the method transforms the video object to the coordinate system of the sprite. The meth od blends (1204) the warped pixels (1202) of the video object with the pixels at corresponding positions in the sprite using rounding average such that each video object in the video sequence provides substantially the same contribution to the sprite.

Abstract: A method and system for the downhole separation and injection of surface water and water contained in a produced mixture from an underground formation of a hydrocarbon well containing hydrocarbon and water. Downhole separation of the produced mixture into a predominately water component and predominately hydrocarbon component is achieved using an oil-water separator. Surface water is delivered to a downhole fluid- driven pump under pressure so as to drive the pump. The downhole-separated predominately water component of the produced mixture is directed to the pump, by way of the pump and combined with surface water to obtain a combined fluid. The combined fluid is directed to a downhole injection formation by way of the pump. Oil is transported to the head of the well either naturally under the eruptive force of the well, or with the assistance of regular artificial lift methods, including gas-lift. This invention allows for injection of surface water and downhole-separated water in the same wellbore while producing oil to surface.

Abstract: The invention relates to a process for preparing diisobutylene (DIB) from an i-butene-containing C4 raffinate I, in which the C4 stream is passed through a first hydroisomerization reactor (A) and a fractionation column (B) and is thus largely freed of 1-butene and 2-butene. It is subsequently dimerized over an acidic catalyst installed in a reactive column (E). The feed stream to this reactive column contains not only i-butene but also butanes which make the reaction temperature in the fixed bed controllable by removal of the heat of reaction. In the fractionation column (B), a side stream can be subjected to a further hydroisomerization in a reactor (C).
