Revolutionary Neuromorphic Visual Sensor Accurately Detects and Predicts Moving Objects with Hidden Information

A new bio-inspired sensor can recognise moving objects in a single frame from a video and successfully predict where they will move to.

A team of researchers at Aalto University has developed a new bio-inspired sensor that can detect moving objects in a single video frame and predict their path. This smart sensor is based on neuromorphic vision technology that integrates sensing, memory, and processing in a single device. It can be used in various fields, including automatic inspection, industrial process control, robotic guidance, and autonomous driving technology.

The sensor’s core technology is an array of photomemristors, electrical devices that produce electric current in response to light. This allows the sensor to “remember” whether it has been exposed to light recently. As a result, the sensor doesn’t just record instantaneous information about a scene but also includes a dynamic memory of the preceding instants. This is similar to how the human visual system works.

The sensor’s ability to integrate a series of optical images in one frame is unique. The information of each image is embedded in the following images as hidden information. The final frame in a video, therefore, has information about all the previous frames. This allows the system to detect motion earlier in the video by analyzing only the final frame with a simple artificial neural network.

To demonstrate the technology, the researchers used videos showing the letters of a word one at a time. The photomemristor array could use hidden information in the final frame to infer which letters had preceded it and predict what the word was with nearly 100% accuracy. In another test, the team showed the sensor videos of a simulated person moving at three different speeds. The system was able to recognize motion by analyzing a single frame and predict the next frames accurately.

The accuracy of detecting motion and predicting where an object will be are essential for self-driving technology and intelligent transport. Autonomous vehicles need accurate predictions of how cars, bikes, pedestrians, and other objects will move to make the right decisions. By adding a machine learning system to the photomemristor array, the researchers showed that their integrated system can predict future motion based on in-sensor processing of an all-informative frame.

The researchers believe that their integrated system provides new opportunities in autonomous robotics and human-machine interactions. The in-frame information obtained using photomemristors avoids redundant data flows, enabling energy-efficient decision-making in real-time.

NASA is celebrating the 25th anniversary of International Space Station operations during a live conversation with crew aboard the microgravity laboratory for the benefit of humanity. During a space-to-Earth call at 12:25 p.m. EST Wednesday, Dec. 6, the Expedition 70 crew will speak with NASA Associate Administrator Bob Cabana and Joel Montalbano, space station program manager.

Watch on the NASA+ streaming service at no cost on demand. The discussion also will air live on NASA Television, the NASA appYouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.

On Dec. 6, 1998, the first two elements of the orbital outpost, Unity and Zarya, were attached by crew members of space shuttle Endeavour’s STS-88 mission. Cabana was the commander of the mission and the first American to enter the space station.

Through this global endeavor, astronauts have continuously lived and worked aboard the space station for more than 23 years, testing technologies, performing science, and developing the skills needed to explore farther from Earth. It has been visited by 273 people from 21 countries.

More than 3,300 research and educational investigations have been conducted on station from 108 countries and areas. Many of these research and technology investigations benefit people on Earth, and many lay the groundwork for future commercial destinations in low Earth orbit and exploration farther into the solar system. Together with Artemis missions to the Moon, these proving grounds will help prepare NASA for future human exploration of Mars.

NASA Administrator Bill Nelson, U.S. Environmental Protection Agency (EPA) Administrator Michael Regan, and other United States government leaders unveiled the U.S. Greenhouse Gas Center Monday during the 28th annual United Nations Climate Conference (COP28).

“NASA data is essential to making the changes needed on the ground to protect our climate. The U.S. Greenhouse Gas Center is another way the Biden-Harris Administration is working to make critical data available to more people – from scientists running data analyses, to government officials making decisions on climate policy, to members of the public who want to understand how climate change will affect them,” said Nelson. “We’re bringing space to Earth to benefit communities across the country.”

The U.S. Greenhouse Gas Center will serve as a hub for collaboration between agencies across the U.S. government as well as non-profit and private sector partners. Data, information, and computer models from observations from the International Space Station, various satellite and airborne missions, and ground stations are available online.  

As the lead implementing agency of the center, NASA partnered with the EPA, National Institute of Standards and Technology, and National Oceanic and Atmospheric Administration. Science experts from each of these U.S. federal agencies curated this catalog of greenhouse gas datasets and analysis tools.  

“A goal of the U.S. Greenhouse Gas Center is to accelerate the collaborative use of Earth science data,” said Argyro Kavvada, center program manager at NASA Headquarters in Washington. “We’re working to get the right data into the hands of people who can use it to manage and track greenhouse gas emissions.”

The center’s data catalog includes a curated collection of data sets that provide insights into greenhouse gas sources, sinks, emissions, and fluxes. Initial information in the center website is focused on three areas: 

  • Estimates of greenhouse gas emissions from human activities 
  • Naturally occurring greenhouse gas sources and sinks on land and in the ocean. 
  • Large methane emission event identification and quantification, leveraging aircraft and space-based data   

An example of a dataset is the methane gas information detected by NASA’s EMIT (Earth Surface Mineral Dust Source Investigation) mission. Located on the International Space Station, EMIT is an imaging spectrometer that measures light in visible and infrared wavelengths and thus can measure release of methane on Earth. 

Built on open-source principles, the U.S. Greenhouse Gas Center’s datasets, related algorithms, and supporting code are fully open sourced. This allows anyone to test the data, algorithms, and results. The center also includes user support and an analysis hub for users to perform advanced data analysis with computational resources and an interactive, visual interface for storytelling. NASA encourages feedback and ideas on the center’s evolution. The center is part of a broader administration effort to enhance greenhouse gas information, outlined in the recently released National Strategy to Advance an Integrated U.S. Greenhouse Gas Measurement, Monitoring, and Information System.
