Kaleido is a novel data system for multi-device synchronization. According to the theories of conflict-free replicated data types, Kaleido enables clients to synchronize replicated data types with operations, and gurantees high availability and eventual consistency. Implemented as a back-end as a service, Kaleido server is scalable so as to deal with a huge amount of requests from massive clients...
A fast feature-based intra/inter coding mode selection scheme for the H.264/AVC video coding standard is proposed in this paper. First, three features are extracted from a macroblock to form a feature space. Then, the feature space is partitioned into three regions, i.e., risk-free, risk-tolerable, and risk-intolerable regions, where the risk is calculated using the rate-distortion (RD) performance...
An efficient search range prediction method is proposed to reduce the complexity of motion search in the H.264 video coding standard in this work. The main idea is to predict the temporal search range by modeling the relationship between the rate-distortion (RD) coding gain and the required computational complexity. The proposed algorithm first predicts the temporal search range to maximize the ratio...
A fast multiple reference assignment scheme is proposed to reduce the motion search complexity in the H.264 video standard in this work. The relationship between the temporal search range and the block size is exploited to develop a new algorithm, called the block-size adaptive referencing (BAR) scheme, that assigns a different number of references in a block-size adaptive manner. The expected rate-distortion...
