Abstract
A method and apparatus for image processing, the method comprising obtaining input image data comprising a plurality of pixel intensity values representing a respective plurality of pixel locations, obtaining pixel location data identifying one or more pixel locations represented by compromised pixel intensity values, generating interpolated image data comprising improved pixel intensity values, storing improved image data comprising at least the interpolated image data, and detecting one or more further compromised pixel intensity values based on the improved image data.
Claims20
A method comprising:
- obtaining input image data representative of at least a portion of an image, the input image data comprising a plurality of pixel intensity values representing a respective plurality of pixel locations;
- obtaining pixel location data identifying one or more pixel locations represented by one or more respective compromised pixel intensity values;
- generating interpolated image data comprising one or more improved pixel intensity values representing the one or more identified pixel locations based on the input image data and the pixel location data;
- storing improved image data comprising at least the interpolated image data;
- and
- detecting one or more further compromised pixel intensity values based on the improved image data.
An apparatus comprising:
- at least one processor;
- 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:
- obtain input image data representative of at least a portion of an image, the input image data comprising a plurality of pixel intensity values representing a respective plurality of pixel locations;
- obtain pixel location data identifying one or more pixel locations represented by one or more respective compromised pixel intensity values;
- generate interpolated image data comprising one or more improved pixel intensity values representing the one or more identified pixel locations based on the input image data and the pixel location data;
- store improved image data comprising at least the interpolated image data;
- and
- detect one or more further compromised pixel intensity values based on the improved image data.
A non-transitory computer-readable storage medium comprising computer-executable instructions which when executed by a processor cause operation of an image processing system at least to:
- obtain input image data representative of at least a portion of an image, the input image data comprising a plurality of pixel intensity values representing a respective plurality of pixel locations;
- obtain pixel location data identifying one or more pixel locations represented by one or more respective compromised pixel intensity values;
- generate interpolated image data comprising one or more improved pixel intensity values representing the one or more identified pixel locations based on the input image data and the pixel location data;
- store improved image data comprising at least the interpolated image data;
- and
- detect one or more further compromised pixel intensity values based on the improved image data.
