—Multi-pixel encoding is an emerging method in visual cryptography for that it can encode more than one pixel for each encoding run. Nevertheless, in fact its encoding efficiency is still low because of that the encoding length is invariable and very small for each run. This paper presents a novel multi-pixel encoding called pixel-block aware encoding. It(More)
—In visual secret sharing (VSS) schemes, a secret image can be visually revealed from overlapping shadow images without additional computations. However, the contrast of reconstructed image is much lost. Employing reversing operation to reverse black and white pixels as well as increasing encoding runs is an effective way to improve the contrast. A novel(More)
Visual cryptography allows the information to be encrypted using an encoding system. It does not require a computer to decode. Two transparent images are used in Visual Cryptography. One image contains the secret information and the other image contains random pixels. It is impossible to reveal the secret information from one of the images as both(More)
In the distributed multi-sensor information fusion system composed of 2-D radar and infrared sensor, the problem of the track-to-track correlation is sophisticated because the types of the sensors are different and both of them don’t possess the consistent measurement space, this paper presents a heterogeneous sensors track correlation algorithm(More)
In the distributed multi-sensor data fusion system composed of radar and infrared sensor, the track correlation is one of the key techniques and is also sophisticated because the types of the sensors are different and both of them don’t possess the consistent measurement space. This paper presents a radar-infrared sensor track correlation algorithm(More)
In visual secret sharing (VSS) schemes, a secret image can be visually revealed by overlapping shares. But the contrast of reconstructed image is much lost. A useful way to improve this situation is to employ reversing, a non-cryptographic operation supported by most copy machines, to reverse black and white pixels. Firstly, this paper gives a survey for(More)
In the distributed multi-sensor information fusion system, the track-to-track correlation is one of the key techniques and is also the precondition for implementing track fusion, and the correctness of correlation judged would directly impact on the performance of the whole fusion system. For the information fusion system composed of 2-D radar and infrared(More)
