Imaging Technologies

Electronic imagers and cameras extend the power of human sight. SRI leverages more than five decades of imaging expertise to provide innovative development services and advanced capabilities to clients in many industries.

SRI specializes in the development of high-performance charge-coupled device (CCD) and complementary metal oxide semiconductor (CMOS) image sensors. SRI-designed imagers offer advanced capabilities, ranging from high quantum efficiency and high speed to 100% fill factor and back illumination. Combining novel back-illumination methods and high-speed sensor circuitry, SRI produces unique imagers for the most difficult applications.

SRI meets demanding industrial and scientific sensor requirements in these areas:

  • CCD and electron-multiplying CCD (EMCCD) imagers perform in extreme low-light situations to enhance day- and night-vision systems, including goggles, sights, vehicles, and more

  • Low-light CMOS image sensors for night vision, persistent surveillance, and aerospace applications

  • Scientific imaging solutions for microscopy and biotech applications, as well as DNA sequencing and spectroscopy

  • Time delay integration (TDI) CCD technology enables airborne reconnaissance and satellite imaging, machine vision, and inspection of continuous/web processes

SRI In the News

SRI's low-light CMOS imaging technology is noted in this round-up of products presented at SPIE's annual Defense, Security and Sensing (DSS) event.

Meal logging and calorie counting is still a pretty painful process, but SRI is working on an image recognition technology that could change that.

According to this article, “’The major change now starting to take place in EO/IR imagery integration is the revolutionary transition from analog I2 tubes to digital low-light CMOS based imager technology,’ said SRI's Tom Vogelsong

This article reports that "with the technology Google has licensed from SRI, image stabilization will no longer be a concern ... at least on Android." Google is implementing the SRI 2D technology in its Google Talk application, to deliver better video on Android 3.0+ devices.

This article reports that SRI recently announced that Google has chosen its 2D video stabilization software for Google Talk on Honeycomb tablets.

This article reports that SRI has recently announced it will be providing image stabilization software to take the jiggles from your future Google Talk videocalls.

According to the article, new technologies are emerging that could help identify someone hiding a gun or crude bomb. "In October, SRI Sarnoff unveiled the camera, which it says can be used to scan crowds for people trying to hide weapons or bombs."


Important diagnostic criteria for glaucoma are changes in the 3D structure of the optic disc due to optic nerve damage. We propose an automatic approach for detecting these changes in 3D models reconstructed from fundus images of the same patient taken at different times.

In this paper, published in IEEE Conference on Computer Vision and Pattern Recognition (CVPR), we propose a novel approach to extract primary object segments in videos in the ‘object proposal’ domain.

In this SPIE proceedings paper, SRI describes how its NV-CMOS™ image sensor technology is designed to capture images over the full range of illumination from bright sunlight to overcast starlight.

This paper, published in the Interservice/Industry Training, Simulation & Education Journal, addresses the need within the military to enhance its training capability to provide more realistic and timely training, but without incurring excessive costs in time and infrastructure.

In this paper, published in IEEE Computer Society Conference on Stereo Vision Vision and Pattern Recognition Workshops (CVPRW), 2012. Processing is a critical component of Augmented Reality systems that rely on the precise depth map of a scene.

In this paper, published in ACM '11 Proceedings of the 19th ACM international conference on Multimedia. We study the feasibility of solving the challenging problem of geolocalizing ground level images in urban areas with respect to a database of images captured from the air.

18th IEEE International Conference on Image Processing (ICIP), 2011. In scenes of significantly varying lighting conditions, under and over exposed regions can suffer from a loss of information.

In this paper, published in IEEE International Conference on Healthcare Informatics, Imaging and Systems Biology, we introduce a projective geometry based approach that reconstructs and aligns 3D blood vessel networks given two stereo pairs of optic disc images, in order to aid glaucoma diagnosis.

In this paper, published in IEEE proceedings of the 14th International Conference on Information Fusion (FUSION). Image fusion is an important visualization technique of integrating coherent spatial and temporal information into a compact form.

In this paper, published in 2011 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), we show that with the use of precise 3D Li-dar range data, we are able to build a global consistent database of high precision 3D visual landmarks, which improves the landmark matching accuracy.
