Abstract
A system, comprising a processor; and a memory, the memory including instructions to be executed by the processor to acquire a first image of a scene, acquire a second image of the scene while illuminating the scene, identify pixel blooming in a subtracted image determined by subtracting the first image from the second image, remediating the pixel blooming based on empirically determined parameters, and operate a vehicle based on the subtracted image.
Claims16
A method, comprising:
- acquiring a first image of a scene;
- acquiring a second image of the scene while illuminating the scene;
- identifying pixel blooming in a subtracted image determined by subtracting the first image from the second image;
- remediating the pixel blooming by reducing an intensity of pixel values of a group of bloomed pixels based on a distance measure, wherein the distance measure is calculated based on an absolute value of a log of an L2-norm of a distance from a weighted centroid;
- and
- operating a vehicle based on the subtracted image.
