In recent years, the issue of person re-identification has become more and more popular, which is an important research subject in the field of computer vision, and many models or methods for different predicaments have been proposed successively. Ho

The amorphous thin film metallic glasses (TFMGs) have been studied widely due to their unique properties and ease of fabrication as compared with the bulk metallic glasses (BMGs). Among the many TFMG systems, the W-based TFMG remains unstudied. In th

In this paper, we construct a separable reversible data hiding scheme for encrypted JPEG bitstreams. Our proposed scheme is constructed via a reserving-room-before-encryption manner, that is, the original JPEG bitstream is modified with small distort

In this paper, we study the d-dimensional knapsack problem (d-KP). The problem d-KP is a generalized version of the well-known knapsack problem (1-KP) which is known to be an NP-complete problem. It is also known that there is no fully polynomial-tim

While thin film metallic glass (TFMG) materials have been studied widely due to their easy fabrication process and unique properties, the W-based or W-containing TFMGs have yet to be explored extensively. In this work, four W-containing Zr–W–Ti T

In this paper, we study reversible data hiding schemes for JPEG images and we propose a method which is constructed by embedding secret data into zero quantized coefficients. In the proposed method, consecutive zero quantized coefficients in a fixed
