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 transmission map in original approach. Combining...
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 the cost of obtaining transmission map is...
This paper presents a new resume algorithm for video image which is disturbed by motion blur. For innovation, the new algorithm makes the denoised region of motion object as the primary target, and with the discrete model, it gets valuable result. Firstly, the method calculates the differences between the neighboring frames. Secondly, it calculates the quadrinomial moment pixel by pixel to differentiate...
Decorrelation caused by temporal change and SAR imaging geometry prevents conventional SAR interferometry from monitoring land surface subsidence precisely. In addition, conventional methods donpsilat deal with phase delay which caused by atmosphere. It negatively influences the accuracy of differential synthetic aperture radar interferometry (D-InSAR) for small-scale deformation monitoring. In this...
