Abstract: Provided are a method for image prediction of a multi-view video codec capable of improving coding efficiency, and a computer readable recording medium therefor. The method for image prediction of a multi-view video codec includes partitioning an image to a plurality of base blocks, acquiring information of reference images which are temporally different, acquiring information of reference images which have different views, and predicting a target block based on the acquired information. Accordingly, an image that is most similar to an image of a view to be currently compressed is generated using multiple images of different views, so that coding efficiency can be improved.

Abstract: The present invention relates to a method for reducing to metallic chromium the chromium oxide material found in slag formed in an electric arc furnace during the process of making stainless steel in that furnace. The chromium oxide content of the slag can be effectively reduced to a relatively low concentration by maintaining the slag in a liquid phase while at the same time blowing into the furnace via a carrier gas certain amounts of powdered aluminum dross. In particular, powdered aluminum dross can be blown into the furnace in amounts ranging from about 10 to 20 kg of dross per ton of molten steel in the furnace. Alternatively, powdered aluminum dross can be blown into the furnace in a thrown-in amount which satisfies the equation: 0.5?[Thrown-In Al dross (ton)×100]/[Slag in Furnace (ton)×Cr2O3 (wt %)]?1.0. Via such a method used during the stainless steel making process, the recovery of valuable chromium and the rate of chromium oxide reduction can be increased.
