CONTEXT

The denoising of signals often involves the reduction of pulse-type noise generated by electronic CCD / CMOS sensors or the acquisition electronics associated with them. The size of the processed image is limited because current solutions (median / convolution filters) have limitations in terms of processing speed and sizes of noise filters.

 

DESCRIPTION

The invention provides techniques for implementing and optimizing median / convolution / iterative filters for GPUs. This results in advantageous performance in terms of processing speed, the size of the filters allowed, the quality of the images (for the medians). In addition, the method is applicable to 1D (audio) or 2D (images) signals, and possibly 3D.

 

COMPETITIVE ADVANTAGES

  • Unmatched processing speed (120 billion pixels / second)
  • Superior image quality than standard 2D median filters
  • Usable filter sizes greater than the standards: up to 131x131 pixels

     

MARKETS AND APPLICATIONS

  • Medical imaging : processing of images captured by MRI
  • Microscopy : enhancement of electron microscopy images
  • Audiovisual : image and sound denoising in post-production
  • Geolocation / Telemetry : cleaning of GPS, Radar, Lidar signals

 

DEVELOPMENT STAGE

Validation of the technique in an operational environment (TRL 6)
