With the rapid development of virtual reality and augmented reality technologies, the demand for personalized virtual avatars has become increasingly urgent. Recently, researchers proposed a new technology called URAvatar (Universal Relightable Gaussian Codec Avatar), which allows users to easily generate high-fidelity virtual avatars by scanning with their phones. This innovative achievement not only enhances the visual effects of virtual avatars but also enables users to drive and adjust their avatars in real-time under different lighting conditions. The working principle of URAvatar is based on a complex light transport model, and it differs from previous approaches.

Recently, the results of an AI weapon scanning pilot project in New York City left many astonished. The scanning equipment provided by a tech company named Evolv failed to detect a single gun but flagged 12 knives instead. The image source note: Images generated by AI, Image licensed by service provider Midjourney. This trial, which started at the end of July, lasted only a month and produced disappointing results. According to CBS New York, although the equipment detected 12 knives, it did not result in any arrests.

In recent years, non-destructive imaging technology has made rapid advancements in the field of painting research and preservation. Among these, macro X-ray fluorescence (MA-XRF) analysis stands out, helping experts identify pigments and analyze painting techniques, providing valuable insights into the artist's creative process. However, MA-XRF technology generates large and complex datasets that challenge traditional data analysis methods. Recently, Italian researchers applied deep learning algorithms to spectral analysis of MA-XRF datasets, developing a brand new analysis approach.

Tencent Cloud and Xiaomi have collaborated to launch the new Smart Lock M30 Pro. This product utilizes Tencent's 'palm scanning technology' that leverages AI recognition capabilities of palm prints and palm veins, providing users with a novel and convenient way to unlock securely. This technology is based on Tencent's proprietary 'palm print + palm vein' recognition algorithm, which captures images of the veins beneath the palm skin using near-infrared light for high-precision identity verification. Since every individual's palm vein pattern is unique, this technology not only enhances the convenience of unlocking but also significantly increases security.

Tencent Docs has recently launched an upgraded version of the 'Smart Scan' feature, aimed at providing users with a more convenient and efficient document management experience. This new feature is especially suitable for the back-to-school season when teachers and students need to handle a large volume of materials and documents. Users can access the 'Smart Scan' tool through the Tencent Docs mini program or APP, which offers three core functionalities: scan archiving, handwriting removal, and document management.

Sam Altman's Worldcoin project has garnered widespread attention and controversy for its combination of biometric iris scanning and cryptocurrency. Users obtain specific cryptocurrencies by scanning their irises, with their information linked to the blockchain to provide universal basic income. However, this process has raised concerns about privacy and data security, leading to investigations by more than 14 countries. Worldcoin is under scrutiny in at least 14 countries, including France, the UK, South Korea, and Chile. Privacy officials state they are collaborating with regulatory agencies, but progress on this collaboration has been limited.

The AI-controlled fully automated robot dentist developed by Perceptive in Boston has successfully completed an entire dental surgery for human patients for the first time, operating eight times faster than human doctors. This innovative technology utilizes a handheld 3D volumetric scanner and optical coherence tomography to create a three-dimensional model of the mouth, avoiding X-ray radiation, and can accurately detect 90% of cavities. The robot discusses treatment plans with the patient and human doctors before the surgery, then takes over, planning and swiftly executing the surgical process. The first specialized field is preparing for dental crowns, which typically takes two hours.

The MIT Computer Science and Artificial Intelligence Laboratory has demonstrated an innovative method for training home robots by utilizing iPhone scans of users' home environments, uploading the data to a simulated environment for training. This method aims to address the limitations of traditional robot training in adapting to complex home layouts, lighting, and object placement. Through simulated training, robots can practice millions of times in a virtual world without any real-world loss, significantly enhancing their adaptability. The construction of the environmental database not only strengthens the robots' performance in known environments but also prepares them to face...

During the pandemic, scanning products achieved growth against the trend. IDC reports that the shipment volume of scanners in China increased by 9.7% year-on-year in 2021. Google's Tesseract OCR engine boasts an almost 100% recognition accuracy, greatly addressing data accuracy issues. Quark Scan King has launched a万能 scanning function that supports editing of text and table content, enhancing user experience. Quark Scan King addresses young users' pain points with automatic document format and layout recognition. Large model technology supports Quark Scan King's handwriting and formula recognition accuracy reaching 99%, leading the industry.

Using AI to analyze OCT scanning data of the eyes can detect differences in the thickness of the cellular layers between patients with Parkinson's disease and non-patients. Researchers believe that eye scans can facilitate early detection of the disease and hope for routine implementation in the future. OCT scanning is non-invasive and has been widely used in ophthalmology to reveal cellular layer information.
