Abstract
The invention relates to a method, a device, an image quality evaluation module and a computer program product for determining the quality of an image. In an input image, at least one color component is iteratively restored with a deblur parameter, which deblur parameter is increased at each iteration. The iteration is stopped when an overshooting in the final image exceeds a predetermined value. After the iteration has been stopped, a number of iterations is defined and the quality of the image is determined according to the number of iterations.
Claims27
A method comprising:
- using a processor to cause an apparatus to perform:
- restoring iteratively at least one color component in an input image with a deblur parameter,
- increasing said deblur parameter at each iteration,
- stopping the iteration when an overshooting in the final image exceeds a predetermined value,
- defining the number of iterations and
- determining quality of an image is determined according to the number of iterations.
A device comprising an image processing system being configured to
- restore at least one color component in an input image iteratively with a deblur parameter,
- to increase the deblur parameter at each iteration,
- to stop the iteration when an overshooting in the final image exceeds a predetermined value,
- to define the number of iterations and
- to determine the quality of an image according to the number of iterations.
An apparatus comprising
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- restore at least one color component in an input image iteratively with a deblur parameter,
- increase the deblur parameter at each iteration,
- stop the iteration when an overshooting in the final image exceeds a predetermined value,
- define a number of iterations and
- determine the quality of the image according to the number of iterations.
A non-transitory computer-readable storage medium encoded with instructions that, when executed by a computer perform
- restoring at least one color component in an input image iteratively with a deblur parameter,
- increasing the deblur parameter at each iteration,
- stopping the iteration when an overshooting in the final image exceeds a predetermined value,
- defining a number of iterations and
- determining the quality of the image according to the number of iterations.
