Image restoration

Image restoration is defined as the process of taking a degraded image and performing some operation to restore or improve the quality of the images. A typical example would be to reduce blur in the image caused by lens distortion or motion induced by camera.

Degraded image -> some operation -> Output image with better quality

It is to be noted that image restoration is a difficult task because it involves recovery of lost information. To restore a degraded image we are trying to solve an ill-posed problem in mathematical terms. Image restoration can be categorized as solving an inverse problem.

Examples: Denoising, Deblurring, Dehazing, Deraining, etc.


  1. Medical: image denoising
  2. Life Sciences: Microscopy image super resolution
  3. Automotive: Defogging and Deraining
  4. Surveillance: Deraining and Dehazing
