Abstract
A system for generating a dark current residual image is configurable to generate a weighted average image by: (i) determining a region-based weight value for each pixel of an input image based upon a light level of a region in which the pixel lies; and (ii) combining the input image with a previous image using the region-based weight values for each pixel of the input image. The system is also configurable to generate a dark current residual image based upon the weighted average image.
Claims20
A system for generating a dark current residual image, comprising:
- one or more processors;
- and
- one or more hardware storage devices that store instructions that are executable by the one or more processors to configure the system to:
- identify a set of target pixels within an input image by performing a template matching process, wherein the template matching process comprises:
- identifying a target pixel template;
- identifying a pixel window associated with each pixel of the input image;
- determining a similarity score for each pixel of the input image by determining a similarity between each pixel window and the target pixel template;
- and
- defining the set of target pixels to include each pixel of the input image for which the similarity score satisfies one or more similarity conditions;
- and
- generate a dark current residual image based upon the set of target pixels.
