There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

The author systematically examines one of the important issues of information — establishing the market price. He introduces the concept of «search» — where a buyer wanting to get a better price, is forced to question sellers. The article deals with various aspects of finding the necessary information.

Economics of Information

With the advent of the Internet of Things (IoT), various industries have made considerable progress, including agriculture, utilities, manufacturing, and retail. IoT solutions help to increase productivity and efficiency in factories and workplaces. Meanwhile, in smart cities, interconnected traffic lights and parking lots are established through IoT technologies to alleviate traffic problems. Currently, IoT security has become the main concern in practical applications. In the field of Artificial Intelligence of Things (AIoT), AI is realized through various technical supports, especially machine learning (ML) technology. ML can analyze data, learn from them, and infer or predict with specific algorithms. ML can solve practical problems that are difficult for simple rules using data and is widely used in complex tasks, such as search engine (SE), autonomous driving (AD), machine translation (MT), medical diagnosis, spam filtering, computer games, face recognition, data matching, and credit rating. In particular, ML technology can shape the surrounding environment into a personal preference under IoT, which is very practical.

This paper aims to study the concept of the metaverse as reflected in the Three-Body game in the TV series The Three-Body Problem, as well as the current development status of the metaverse in the real world. Firstly, the Three-Body game in The Three-Body problem is analyzed and explained to uncover the underlying metaverse knowledge. Then, through a literature review, the implementation and application scenarios of the metaverse in various industries are investigated from the databases Web of Science and Scopus, using keywords such as “metaverse”, “Three-Body”, “virtual world”, “virtual reality games”, and “human-computer interaction”. Nearly 10,000 relevant articles were retrieved, and 20 articles were selected for in-depth qualitative and quantitative analysis. Subsequently, the content of the literature is summarized from three aspects: the current development status of the metaverse, advancements in virtual reality technology, and advancements in human-computer interaction technology. The application status and technological progress of the metaverse in various industries and the existing technological limitations are discussed. By extending the concept of the metaverse from science fiction, this paper provides research ideas for the future development of the metaverse.

From Three-Body game to Metaverse

Artificial intelligence technologies such as computer vision (CV), machine learning, Internet of Things (IoT), and robotics have advanced rapidly in recent years. The new technologies provide non-contact measurements in three areas: indoor environmental monitoring, outdoor environ-mental monitoring, and equipment monitoring. This paper summarizes the specific applications of non-contact measurement based on infrared images and visible images in the areas of personnel skin temperature, position posture, the urban physical environment, building construction safety, and equipment operation status. At the same time, the challenges and opportunities associated with the application of CV technology are anticipated.

Computer Vision Technology for Monitoring of Indoor and Outdoor Environments and HVAC Equipment: A Review

In this paper we present a dense ground truth dataset of nonrigidly deforming real-world scenes. Our dataset contains both long and short video sequences, and enables the quantitatively evaluation for RGB based tracking and registration methods. To construct ground truth for the RGB sequences, we simultaneously capture Near-Infrared (NIR) image sequences where dense markers - visible only in NIR - represent ground truth positions. This allows for comparison with automatically tracked RGB positions and the formation of error metrics. Most previous datasets containing nonrigidly deforming sequences are based on synthetic data. Our capture protocol enables us to acquire real-world deforming objects with realistic photometric effects - such as blur and illumination change - as well as occlusion and complex deformations. A public evaluation website is constructed to allow for ranking of RGB image based optical flow and other dense tracking algorithms, with various statistical measures. Furthermore, we present an RGB-NIR multispectral optical flow model allowing for energy optimization by adoptively combining featured information from both the RGB and the complementary NIR channels. In our experiments we evaluate eight existing RGB based optical flow methods on our new dataset. We also evaluate our hybrid optical flow algorithm by comparing to two existing multispectral approaches, as well as varying our input channels across RGB, NIR and RGB-NIR.
