SiamVGG: Visual Tracking using Deeper Siamese Networks

Recently, we have seen a rapid development of Deep Neural Network (DNN) based visual tracking solutions. Some trackers combine the DNN-based solutions with Discriminative Correlation Filters (DCF) to extract semantic features and successfully deliver the state-of-the-art tracking accuracy. However, these solutions are highly compute-intensive, which require long processing time, resulting unsecured real-time performance. To deliver both high accuracy and reliable real-time performance, we propose a novel tracker called SiamVGG. It combines a Convolutional Neural Network (CNN) backbone and a cross-correlation operator, and takes advantage of the features from exemplary images for more accurate object tracking. The architecture of SiamVGG is customized from VGG-16, with the parameters shared by both exemplary images and desired input video frames. We demonstrate the proposed SiamVGG on OTB-2013/50/100 and VOT 2015/2016/2017 datasets with the state-of-the-art accuracy while maintaining a decent real-time performance of 50 FPS running on a GTX 1080Ti. Our design can achieve 2% higher Expected Average Overlap (EAO) compared to the ECO and C-COT in VOT2017 Challenge

A Study on the Changes of Gender Morality in China: Centered on the Male Experience in the "Love Letter" Incident (1900-1930)

In the 20th century, China was an era of significant social changes, experiencing the impact of abolishing old and establishing new in politics, economy, culture, and other aspects. In terms of sexual morality, traditional sexual morality was criticized by Chinese youth and intellectuals, while new sexual morality was disseminated among young people. The love letter incident that occurred in such a social context is a representative event of young men and women actively breaking traditional sexual morality and constructing new sexual morality. This article takes two love letter events that occurred in China in the early 20th century and the 1920s as research objects, focusing on the experiences of young men in the love letter events. Using the method of seeking differences, it first clarifies the thoughts and expressions of young men on the issue of love in the love letter text. Secondly, it analyzes the views and debates of public power and social elites on the events in the love letter events, thereby revealing the end of the old sexual morality and the development of new sexual morality in modern China. In the two love letter events, the content of the young man\u27s love letters both demonstrated his longing for new sexual morality. Qu Jiang faced criticism, while Qiu Gongyi received sympathy. The different experiences of the male protagonist in the two love letter events reflect the progress of China\u27s modernization process in terms of neutral moral concepts

A Study on the Interaction between Gender Morality and Free Love in Early 20th Century China : Centered on Du Cheng Shu&Qu Jiang\u27s Love Letter

This article attempts to answer the question of "love" and why it has been prohibited from entering the public sphere in Chinese history. This article takes the "Love Letter Incident" as a case study and uses the process tracking method to analyze the love letter incident between Du Chengshu (杜成淑) and Qu Jiang (屈疆). In this event, various social groups interacted on this matter, so this article horizontally compared the thinking and self-expression of young men and women in the face of love issues and vertically explored the premature and delayed disclosure of love issues under the trend of gender equality in China since the early 20th century. Examining and evaluating love issues by various parties in the public sphere is necessary for private love writing to move toward the public sphere. Through various evaluations of love letters, the issue of love has entered the public sphere. However, in China at the beginning of the 20th century, the issue of love still faced scrutiny from traditional Chinese gender morality and morality, making it difficult for love issues to be made public. This article finds that in early 20th-century China. The concept of "gender equality" accompanied by China\u27s modernization movement (May Fourth Movement) was valued by society, and the morality of "gender equality" has never been established. However, Chinese society still maintains an unfriendly attitude towards women, and the perception of gender inequality is still considered normal

Numerical Random Periodic Shadowing Orbits of a Class of Stochastic Differential Equations

This paper is devoted to the existence of a true random periodic solution near the numerical approximate one for a kind of stochastic differential equations. A general finite-time random periodic shadowing theorem is proposed for the random dynamical systems generated by some stochastic differential equations under appropriate conditions and an estimate of shadowing distance via computable quantities is given. Application is demonstrated in the numerical simulations of random periodic orbits of the stochastic Lorenz system for certain given parameters

Joint measurement of multiple noncommuting parameters

Although quantum metrology allows us to make precision measurements beyond the standard quantum limit, it mostly works on the measurement of only one observable due to the Heisenberg uncertainty relation on the measurement precision of noncommuting observables for one system. In this paper, we study the schemes of joint measurement of multiple observables which do not commute with each other using the quantum entanglement between two systems. We focus on analyzing the performance of a SU(1,1) nonlinear interferometer on fulfilling the task of joint measurement. The results show that the information encoded in multiple noncommuting observables on an optical field can be simultaneously measured with a signal-to-noise ratio higher than the standard quantum limit, and the ultimate limit of each observable is still the Heisenberg limit. Moreover, we find a resource conservation rule for the joint measurement
