Patent Status

Provisional patent submitted

Market

Image enhancement software market

Highlights

  • Image upscaling, or enlargement of image size, results in blurring of edges and loss of image quality
  • Although digital cameras produce high-resolution images, there still exist huge numbers of low resolution images as well as low-grade sensors found in mobile devices and surveillance systems that produce low-resolution images and video frames that require resolution enhancement.

Our Innovation

New image processing algorithm based on example-based super-resolution that results in a high-quality and efficient single-image upscaling technique

Image upsampling exploits local scale-similarity in natural images. When downscaled, the patches (yellow squares) are very similar to their cropped version (red squares).

Key Features

  • Algorithm produces high-quality, sharp images
  • Reduces the process search time without compromising quality
  • Simple, efficient, and trivially parallel algorithm enables increase in the resolution of video sequences with no algorithmic modifications and at reasonable running times

Development Milestones

Seeking licensing agreements with image processing and editing software developers

The Opportunity

Can be employed with any image editing software as well as software for adapting videos to new HD standards
