Abstract
The present disclosure relates to a method for improving an estimation process, comprising providing an image; detecting a failure area within said image to obtain a failure area map; obtaining a motion or disparity estimation map containing estimation vectors determined in an estimation process; providing a local direction model, LDM, map comprising LDM vectors determined on the basis of said estimated vectors and said detected failure area, and adjusting said estimation process dependent on the local direction model map.
Claims18
A method for improving an estimation process on a device having a processor and a memory, comprising:
- providing an image, using the processor,
- detecting a failure area within said image to obtain a failure area map, the failure area being an area that is prone to failure in the estimation process, using the processor,
- obtaining a motion or disparity estimation map and determining, in the motion or disparity estimation map, estimation vectors in the estimation process, using the processor,
- providing a local direction model (LDM) map comprising LDM vectors determined on the basis of said estimated vectors and said detected failure area, using the processor,
- adjusting said estimation process dependent on the local direction model map, using the processor, and
- controlling a display to display an interpolated image produced by the estimation process, using the processor.
A device for providing an improved disparity or motion estimation map, comprising:
- a processor;
- and
- a memory storing code that, when executed by the processor, controls the processor to
- detect a failure area within an image and to provide a failure area map, the failure area being an area that is prone to failure in an estimation process,
- obtain a motion or disparity estimation map and determine in the motion or disparity estimation map, estimation vectors in the estimation process,
- provide a local detection model (LDM) map comprising LDM vectors determined on the basis of said estimated vectors and said detected failure area,
- adjust the estimation process dependent on the local direction model map, and
- control a display to display an interpolated image produced by the estimation process.
A non-transitory computer-readable recording medium that stores therein a computer program product, which, when executed by a processor, causes the processor to
- detect a failure area within an image and to provide a failure area map, the failure area being an area that is prone to failure in an estimation process,
- obtain a motion or disparity estimation map and determine, in the motion or disparity estimation map, estimation vectors in the estimation process,
- provide a local detection model (LDM) map comprising LDM vectors determined on the basis of said estimated vectors and said detected failure area,
- adjust the estimation process dependent on the local direction model map, and
- control a display to display an interpolated image produced by the estimation process.
