In this paper, we propose an improved image dehazing algorithm using dark channel prior and Multi-Scale Retinex. Main improvement lies in automatic and fast acquisition of transmission map of the scene. We implement the Multi-scale Retinex algorithm on the luminance component in YCbCr space, obtain a pseudo transmission map whose function is similar to the(More)
A polarization-based method for water hazards detection is presented. The concept of polarization is introduced to computer vision to detect water hazards for autonomous off-road navigation. This method is based on the physical principle that the light reflected from water surface is partial linearly polarized and the polarization phases of them are more(More)
With the development of the semiconductor industry, more processors can be integrated onto a single chip. Network-on-Chip (NoC) is an efficient solution for the interconnections on chip for many-core system with many processor cores on chip. However, enhancing performance with lower power consumption is still a challenge. The core issue is the mapping of(More)
In this paper, we propose a simple but effective method for visibility restoration from a single image. The main advantage of the proposed algorithm is no user interaction is needed, this allows our algorithm to be applied for practical applications, such as surveillance, intelligent vehicle, etc. Another advantage compared with others is its speed, since(More)
With the development of the semiconductor technology, more processors can be integrated onto a single chip. Network-on-Chip is an efficient communication solution for many-core system. However, enhancing performance with lower energy consumption is still a challenge. One critical issue is mapping applications to NoC. This work proposed an online mapping(More)
Considering the shortcomings of exiting watermarking algorithm, an adaptive robust blind watermarking algorithm in DCT Domain is proposed. It divides color image luminance component into 8×8 bocks for DCT transform in Color Space, then embeds binary watermark in its middle frequency coefficients in DCT domain, therefore, the embedding and extraction(More)
Because of the shortage of the traditional methods for evaluating regional innovation capability, it presents a new method based on rough set and BP neural network in this paper. Firstly, index system for evaluating about regional innovation capability is set up, and then rough set is used to simplify the attributes of the index system, it will ease the(More)
Network on Chip (NoC) plays an important role in manycore system. Recent researches on NoC focus on the design and optimization on network separately. This paper describes a tightly coupled NoC router architecture. In this architecture, the router and the core are designed as a whole. The router uses on-chip storage to improve the network performance.(More)
This paper reports a novel GaAs micromachined accelerometer based on the meso-piezoresistive effects of resonant tunneling diodes (RTDs). The sensitive unit of the accelerometer is the RTD which is located at the root of the beams. Based on the meso-piezoresistive effects of RTD, the accelerometer transduces acceleration into electrical signal output. This(More)
