Aiming at the information overload caused by rich resources of Broadcast Television programs, this paper puts forward Broadcast Television Programs Recommendation Technology based on user clustering. According to user rating data and programs broadcasting data, we cluster users by the improved K-MEANS algorithm, divide the users with similar viewing preference into the same community groups, and generate...
Building effective and efficient appearance models is a challenging task for robust object tracking. Online learned strategy is widely used to solve appearance changes for its adaptive ability. However, it will introduce potential drifting problems for the accumulation of errors during the self-updating. As a result, this paper attempts to create the visual object appearance model using cloud model...
This paper proposes the software watermarking algorithm based on Chinese remainder theorem, and introduces the authentication center to certify the watermark, to solve the problem that equation re-sorting algorithm are easily attacked by the random re-sequencing technology. The algorithm further disposals the sequence obtained, the selected divisor sequence and the multiple to generate the key, which...
Evaluating coding efficiency in early coding stage is important in modern RDO compression methods. Bit-plane coding algorithms such as SPIHT are widely used in many scalable coders. The locality of a spatial-oriented tree (SOT) affects the coding efficiency of a SPIHT coder. In this paper, a fast algorithm is proposed to determine the numbers of bits to be consumed at all coding levels for a SPIHT...
Blind image quality assessment refers to the problem of evaluating the visual quality of an image without any reference. In this paper, we present a no-reference blur metric for images and video using information contained in the image itself. We look at the sharpness of the sharpest edges in the blurred image, which contains information about the blurring, and is not on the image contents. The experimental...
