Abstract: A motion estimation apparatus and method (carried out electronically) provides for encoding of multiview video, such as stereoscopic video, by providing motion estimation for pixels in a dependent eye view, using motion vector information from a colocated group of pixels in a base eye view and neighboring pixels to the colocated group of pixels in the base eye view. The method and apparatus encodes a group of pixels in a dependent eye view based on the estimated motion vector information. The method and apparatus may also include obtaining a frame of pixels that includes both base eye view pixels and dependent eye pixels so that, for example, frame compatible format packing can be employed. In one example, estimating the motion vector information for a block of pixels, for example, in a dependent eye view is based on a median value calculation of motion vectors for a block of pixels in a base eye view and motion vectors for neighboring blocks of pixels to the colocated group of pixels in the base eye view.

Abstract: A method and apparatus are described for performing video encoding mode decisions. A down-scaled frame is received that includes a macroblock corresponding to a first subset of macroblocks of a first area in a full-scale frame. A first average motion vector is calculated for the first subset of macroblocks, and a second average motion vector is calculated for a second subset of macroblocks of a second area surrounding the first subset of macroblocks. A comparison of a threshold to a distance measure between absolute values of the first and second average motion vectors is performed. A prediction mode for the macroblock in the down-scaled frame is determined based on the comparison to generate predicted blocks.

Abstract: A login method and device, and a terminal and a network server are disclosed, which relate to communications technologies. In the method, acquire an account waiting for login and a first password, and judge whether the first password is the same as a local password bound with the pre-stored account.

The present invention introduces a custom password (i.e., the first password), thus avoids the complexity to enter an actual login password (i.e., the second password) and the unsafety to remember the actual login password in a terminal, and enhances the convenience and safety for login and offers greater user experience.

Abstract: An efficient motion estimation method and apparatus for 3D stereo video encoding is described herein. In an embodiment of the method, an enhancement layer motion vector for a frame is determined by obtaining a motion vector of a co-located macroblock (MB) from the same frame of a base layer. The motion vectors of a predetermined number of surrounding MBs from the same frame of the base layer are also obtained. A predicted motion vector for the MB of the frame in the enhancement layer is determined using, for example, a median value from the motion vectors associated with the co-located MB and the predetermined number of surrounding MBs. A small or less than full range motion refinement is performed to obtain a final motion vector, where full range refers to the maximum search range supported by an encoder performing the method.

Abstract: A method for determining a macroblock (MB) coding mode for a current MB in a dependent view. A window around a co-located MB in a base view is determined, wherein the co-located MB is a MB in the base view having a same location as the current MB in the dependent view. A coding mode complexity value (CMCV) is determined for each MB in the window, wherein the CMCV is based on a coding mode used to encode the MB. Rate distortion optimization (RDO) is performed for the current MB using a reduced number of coding modes if a total CMCV for all MBs in the window is less than a threshold, or using all supported coding modes if the total CMCV for all MBs in the window is greater than the threshold. A coding mode for the current MB is determined based on the RDO results.
