TOKYO—Toshiba Corporation (TOKYO: 6502) has developed Few-Shot Object Detection AI, an image recognition-based technology capable of immediately detecting a new object with unprecedented accuracy. Simply registering a single image primes the technology to recognize new products and parts in production and logistics. The company designed the new AI to be useful in situations where new objects appear frequently, such as plants that regularly process updated and improved products and parts, and distribution centers that are constantly required to handle new merchandise. There are worldwide efforts to convert sensing data from the field into valuable information and return it to the field as feedback, thereby increasing productivity, quality, and efficiency in operations. Image recognition AI, which detects people and objects in images, is particularly valuable for analysis aiming to improve productivity, automate processes, and reduce workloads. However, one drawback of the technology is the need to prepare large amounts of image data for training to detect new objects every time they are needed in the situations where the technology is used. Toshiba’s new Few-Shot Object Detection AI is automatically pre-trained to recognize the shapes of non-target objects in the training images, a proprietary development in the training process that enables the AI to detect new objects with the registration of a single image and no retraining in the field. In an assessment of detection accuracy based on a public dataset, the technology achieved unprecedented accuracy. Companies that operate factories and plants that handle many different parts and equipment have been reluctant to incorporate AI into their processes because of the time and effort required for retraining every time something changes. Few-Shot Object Detection AI is easy to introduce and use, helping these companies digitize their operations and promote digital transformation to improve productivity, quality, and efficiency. Toshiba is scheduled to give a presentation on the details of the new technology on May 25, 2022 at ICIAP 2021, the 21st International Conference on Image Analysis and Processing.

TOKYO—Toshiba Corporation (TOKYO: 6502) has developed artificial intelligence (AI) for detecting anomalies during infrastructure inspections. With only a few reference images of inspection targets and no real-world training, the technology can accurately detect cracks and rust as well as leaks, adhesion of foreign material, detachment of parts, and other infrequent, untrained anomalies. This new AI not only reduces inspection workloads—particularly those that imperil workers or require travel, such as atop steel towers in the mountains, under elevated bridges, on slopes, and under solar panels—it also performs well in real-world situations where the scarcity of images from the field has hampered past efforts to use AI. The technology uses features from pre-trained deep learning models to compare inspection photographs against reference images, and thus does not require real-world training as in the case of conventional AI. Toshiba’s proprietary correction technology enables the new AI to detect anomalies with high accuracy even when inspection photographs are taken from different angles than in the reference images, and also limits false positives in the case of unique patterns that are actually normal. In an assessment based on a public dataset, the AI was 91.7% accurate, the highest figure ever recorded. The new technology automates inspections, reduces workloads, and expedites the discovery of anomalies, helping ensure stable long-term operation of infrastructure. Toshiba is scheduled to give a presentation on the details of this new AI on May 25, 2022 at ICIAP 2021, the 21st International Conference on Image Analysis and Processing, in Italy.

At the Toshiba Co-creation Center “Creative Circuit,” which opened last February as a base for co-creation activities in the Toshiba Group, Toshiba has implemented functions using the company’s latest video recognition AI to create new value with co-creation partners through experiencing the latest technology. As a first step, Toshiba has implemented four functions at Creative Circuit: crowding detection, suspicious behavior detection, unnatural posture detection, and individual recognition. By allowing co-creation partners within and outside of the Toshiba Group to experience AI technology, Toshiba will work with its co-creation partners to create new value from AI technologies, leading to earlier social implementation of Toshiba AI. Furthermore, to make Creative Circuit a safer, more secure, and more creative environment during the COVID-19 epidemic, the company has developed a communication-activity monitoring system that uses a crowding detection function and is operated within Creative Circuit. This system detects the state of crowding while also calculating and displaying communication activity levels to support active communication while preventing excessive crowding, thereby increasing the efficiency and effectiveness of co-creation activities. Toshiba plans to continue introducing new AI functions at Creative Circuit, which will also be used as a base for value creation using AI technology with its co-creation partners, contributing to the creation of innovative solutions for solving social issues and realizing a sustainable society.

TOKYO―Nomura Holdings, Inc. (President and Group CEO, Kentaro Okuda, hereinafter Nomura HD), Nomura Securities Co., Ltd. (Representative Director and President, Kentaro Okuda, hereinafter Nomura Securities), National Institute of Information and Communications Technology (President, Hideyuki Tokuda, Ph.D., hereinafter NICT), Toshiba Corporation (Representative Executive Officer and President and Chief Executive Officer, Satoshi Tsunakawa, hereinafter Toshiba), and NEC Corporation (President and CEO, Takayuki Morita, hereinafter NEC) have jointly verified on the effectiveness and practicality of quantum cryptography for future social implementation using the stock trading operations as a use case, where high-speed, large-volume, low-latency data transmission is strictly required. The test which started in December 2020 is the first in Japan to verify the low-latency and large-volume transmission tolerance of highly secure data transmission conforming to the message transmission format (FIX format), which is a standard format used in actual stock trading operations. As a result, in our assumed use case, we were able to confirm the following two points: (i) the throughput is maintained at a level of a conventional system even if quantum cryptography is applied, and (ii) even if a large number of stock orders are placed, highly secure and high-speed quantum cryptographic communication can be realized without depleting cryptographic keys. The success of this test is expected to accelerate the social implementation of quantum cryptography including the broad range of sector other than finance.

TOKYO— Toshiba Corporation (TOKYO: 6502) has developed a world-first AI technology that can determine actual-scale 3D measurements from only monocular camera images taken under various conditions, such as those taken from a distance with a zoom lens or with autofocus. Using several photos taken from a distance by a monocular camera during infrastructure inspections, this AI facilitates easy measurements of the size of areas for repair without the need to approach dangerous and difficult-to-inspect areas such as high places and inclinations. The conventional use of only a monocular camera provides only relative values, requiring gyroscope to obtain absolute values or basic information about sizes. However, the developed AI can provide absolute values by combining relative depth information obtained from multiple viewpoints of a monocular camera with blur information contained in the captured images. Considering that the average age of infrastructure facilities in Japan now exceeds 35 years, this AI can be used to develop efficient maintenance plans that prioritize and realize appropriate repairs without excess or deficiency. Toshiba has been developing robot-integrated management and inspection image analysis technologies like those shown in Figure 1 to save labor and automate infrastructure inspections, and the newly developed technology improves performance in size measurements. Toshiba will present the details of this technology on November 22 at the British Machine Vision Conference 2021 (BMVC 2021).

TOKYO─Toshiba Corporation (TOKYO: 6502) has developed the AI technology that automatically generates physical models for detecting equipment abnormalities and determining the causes of those abnormalities in social infrastructure equipment. The AI automatically generates a physical model that describes the states and motion of a target device from measured time-series data. In addition, the AI shows not only abnormalities in equipment but also the cause of the occurrence of abnormalities based on physical phenomena, which has been difficult in the past. For example, the model made by the AI might indicate that an increase in equipment temperature is due to clogging dust, making improvement measures easier to formulate. The AI responds to complicated phenomena such as sudden changes in temperature and airflow, and can be applied to the maintenance of infrastructure equipment with complicated mechanism of abnormalities offurencethat is abnormalities with complicated occurrence mechanisms. It will improve reliability of facilities and contribute to resilience in social infrastructure. Toshiba will present the details of this technology on November 5 at IMECE 2021, which will be held online.
