Contrast-based technique to reduce artifacts in wavelength-encoded images
First Claim
Patent Images
1. A system for identifying artifacts in an image comprising:
- an input for receiving images from an imager, said images generated by reflecting light off an object and comprising a first pixel of interest; and
a processor coupled to said input for defining and using at least one contrast value of a second pixel associated with said pixel of interest to identify said artifacts in said image.

Abstract
A system for identifying artifacts in an image. The system includes an input for receiving images from an imager, the images comprising a pixel of interest. The images can be generated by reflecting light off an object. The system further includes a processor coupled to the input for defining and using at least one contrast value of a second pixel associated with the pixel of interest to identify artifacts in the image.

8. A system for processing an image comprising:
-
a light source for emitting light at an object, said object comprising a retroreflector; an imager for capturing a plurality of images of said object by using light reflected from said object, said plurality of images comprising a plurality of pixels; and a processor coupled to said imager for defining and using at least one computed contrast value associated with at least one of said plurality of pixels to identify said retroreflector. - View Dependent Claims (9, 10, 11, 12, 13, 14)
