In this paper, we propose a new secret sharing method for Chinese characters based on non-negative matrix factorization (NMF). Chinese characters can be regarded as binary images, but traditional NMF is only suitable for gray-level images. Therefore, this paper proposes a modified version of NMF for dealing with Chinese characters in binary images. The modified NMF decomposes a Chinese character into...
Steel has played a leading role in the development of human civilization and technology. To achieve the goal of industry 4.0 for steel industry, intelligent automated manufacturing becomes increasingly important. One of the key steps on the automatic production line of steel products is automatic inspection of surface detects. In this paper, we propose a fast vision-based surface inspection framework...
Currently, most of the human detection methods are based on low-level features. In this paper, we proposed a middle-level feature generation method based on non-negative matrix factorization (NMF) for human detection. We also proposed an improvement scheme to guarantee that a better middle-level feature can be achieved. The proposed scheme can be applied to a complex background and the experimental...
At present, image and video descriptors have been widely used in many computer vision applications. In this paper, a new hierarchical multiscale texture-based image descriptor for efficient image matching is introduced. The proposed descriptor utilizes mean values at multiscale levels of an image region to convert the image region to binary bitmaps and then applies binary operations to effectively...
This paper presents a novel scheme for human action recognition. First of all, we employ the curvature estimation to analyze human posture patterns and to yield the discriminative feature sequences. The feature sequences are further represented into sets of strings. Consequently, we can solve human action recognition problem by the string matching technique. In order to boost the performance of string...
Trusted transaction is becoming more and more important as malicious user or agent inside the network may compromise the upcoming transaction. Trusted Computing mutual remote attestation mechanism is a relative new approach to overcome this problem. But limited computation capability of TPM device on the sever side is an obvious bottleneck of scalable performance. by introducing a novel high efficient...
Multi-sensor information fusion (MSIF) is an emerging technology, which has received great attention. A recent achievement about the MSIF-based filtering and control is summarized, which includes the MSIF filter and MSIF control. The filtering algorithm, the linear and nonlinear fusion control, and economic system control are extensively reviewed. Some typical application results of MSIF are given,...
A new sliding mode control approach with varying boundary layers is proposed. The key feature of the proposed control scheme is using varying boundary layers instead of fixed boundary, which are usually employed in conventional sliding mode control. Although the conventional quasi sliding mode control can solve the chattering problem partly, the stability of the system is affected. By incorporating...
