Abstract: Enhancing image dynamic range is described. An input video signal that is represented in a first color space with a first color gamut, which is related to a first dynamic range, is converted to a video signal that is represented in a second color space with a second color gamut. The second color space is associated with a second dynamic range. At least two (e.g., three) color-related components of the converted video signal are mapped over the second dynamic range.

Abstract: A vessel includes a hull with a turret, a cavity in the turret and a mooring buoy releasably attached in the cavity, the buoy including a buoyant body and carrying a number of risers, extending to a subsea hydrocarbon well and a number of anchor lines connected to the sea bed, wherein upon connection of the buoy to the cavity, the buoy is attached to a pulling member connected to a winch on the vessel for lifting of the buoy. Each anchor line and/or riser at its upper end is connected to a stopper member, the stopper member being attached to the pulling member, wherein during lifting, each anchor line and/or riser and the stopper member are movable relative to the buoyant body in a length direction of the anchor lines and/or risers, and wherein after connection of the buoyant body to the cavity, the stopper member is engaged with an abutment member on the buoyant body to support the anchor line and/or riser weight off the body.

Abstract: A first image stream has a first dynamic range and a first color space. First and the second image streams are received in a layered codec. The second image stream has a second dynamic range, which is higher than the first dynamic range. The first image stream is in the codec's base layer; the second image stream is in its enhancement layer. The first image stream is encoded to obtain an encoded image stream, which is decoded to obtain a decoded image stream. The decoded image stream is converted from the first non-linear or linear color space to a second, different color space to obtain a color converted image stream. A higher dynamic range image representation of the color converted image stream is generated to obtain a transformed image stream. Inverse tone mapping parameters are generated based on the transformed image stream and the second image stream.

Abstract: One aspect relates to a method for producing an alloy characterized by grinding tantalum to form a tantalum powder and grinding tungsten to form a tungsten powder; mixing the tantalum powder and the tungsten powder to form a blended powder. The weight fraction of tungsten powder in the blended powder is larger than in the desired alloy. A blended body is produced from the blended powder by a powder metallurgical route. A pre-alloy is produced by a first melting of the blended body and at least a fraction of at least one further metal by a melt metallurgical route. The alloy is produced by a second melting of the pre-alloy and the remaining fraction of at least one metal by a melt metallurgical route.

Abstract: Optimal error metric function for motion estimation is determined and used for video coding and/or video processing of images. To do so, an initial motion estimation using an initial error metric function can be performed. This can produce motion prediction errors. If the initial error metric function is not the optimal error function, then a final motion estimation is performed using a selected optimal error metric function. In some embodiments, a shape of error distribution can be used to determine the optimal error metric function. Some example systems or devices for this motion estimation can include systems or devices for compression, temporal interpolation, and/or super-resolution processing.
