A 671G0PS/W Semantic Analysis SoC (SASoC) is implemented in 90 nm CMOS technology. Two stream processing systems are integrated with a power-aware frequency scaling technique to simultaneously accelerate video processing and machine-learning algorithms. The input data rate reaches 76.8 Gpixel/s for video processing and 51.2 Gdimension/s for machine-learning algorithms.
K-Means is a clustering algorithm that is widely applied in many fields, including pattern classification and multimedia analysis. Due to real-time requirements and computational-cost constraints in embedded systems, it is necessary to accelerate K-Means algorithm by hardware implementations in SoC environments, where the bandwidth of the system bus is strictly limited. In this paper, a bandwidth...

A new and efficient algorithm to find the fingertips for human computer interface is proposed in this paper. The fingertip positioning algorithm of this paper combines particle filtering with particle random diffusion to find the different fingertips quickly and robustly. There are two special methods used in this algorithm, which are particle random diffusion and fingertip particle selection. Without...
A robust video object segmentation algorithm for complex conditions in surveillance systems is proposed in this paper. This algorithm contains an unsupervised K-Means background clustering technique to model the temporal distribution in RGB domain for each spatial position. Based on the proposed background model, the object mask generation process integrates noise reduction, cast shadow cancellation,...
