Summary of the technology
Knowhow - Method for Estimating the Amount of Noise in an Image
Project ID : 10-2009-2253
Description of the technology
Enables estimation of presence of noise as well as amount of noise
Imaging / Computer Graphics, Digital Image Sensors
Image-processing applications range from industrial uses and security systems to transportation and medical technology
All digital cameras, digital scanners and similar devices must estimate amount of noise in captured image. If the captured image is noisy the imaging device processes it to remove noise; if the captured image is clean the device must refrain from processing it.
Method for estimating the amount of noise in an image captured by a sensor allows the device to estimate not just whether or not an image is noisy, but also provides an accurate estimate of the amount of noise present.
Results of noise estimation were significantly more accurate than the state-of-the-art
Noise estimation on complex image with many edges and texture data (below). With low noise standard deviation other methods perform poorly; this method much better.
Image-processing systems are used in quality control, industrial inspection, metrology for visually guided machines and to recognise components, symbolic characters and codes; robotics; driver assistance systems
