Motion Estimation (ME) is the most computationally intensive part in the whole video compression process. The ME algorithms can be divided into full search ME (FS) and fast ME (FME). The FS is not suitable for high definition (HD) frame size videos because its relevant high computation load and hard to deal with complex motions in limited search range. A lot of FME algorithms have been proposed which...
The H.264/AVC inter-prediction is performed for variable block-size motion estimation (VBSME) such as 16times16, 16times8, 8times16, 8times8, 8times4, 4times8 and 4times4, it cause the high complexity for H.264 motion estimation (ME). This investigation develops an architecture for a combined fast motion estimation algorithm with edge information mode decision (EIMD) and predict hexagon search (PHS)...
This paper proposes a parallel architecture for a successive elimination algorithm (SEA), which is used in block matching motion estimation. SEA effectively eliminates the search points within the search window and thus decreases the number of matching evaluation instances that require very intensive computations compared to the standard full search algorithm (FSA). The proposed architecture for SEA...
The performance of a cellular visual microprocessor ASIC and FPGA implementation is described. The architecture in general is composed of a regular sensor readout circuit array, prepared for 3D face-to-face type sensor integration, and one (or several cascaded) array(s) of customizable processors. The individual arrays derived from the same general RTL description and could be of different dimension,...
