Knowhow - Method for Estimating the Amount of Noise in an Image
Project ID : 10-2009-2253

Yissum - Research Development Company of the Hebrew University

Description of the technology

Available Knowhow

Enables estimation of presence of noise as well as amount of noise


Imaging / Computer Graphics, Digital Image Sensors

Development Stage

Working prototype


Available Knowhow


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.

Our Innovation

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.

Key Features

  • 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.

The Opportunity

  • 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
