Abstract
A computer, including a processor and a memory, the memory including instructions to be executed by the processor to acquire a first image from a first camera by illuminating a first object with a first light and determine an object status as one of a real object or a counterfeit object by comparing a first measure of pixel values corresponding to the first object to a threshold.
Claims20
A computer, comprising:
- a processor;
- and
- a memory, the memory including instructions executable by the processor to:
- acquire a first image from a first camera by illuminating a first object with a first light;
- determine a first measure of pixel values based on the first object;
- acquire a second image of a second object with the first camera by illuminating the second object with the first light, wherein the second object is a real object;
- determine a second measure of pixel values based on the second object in the second image, wherein the second measure of pixel values is based on a second mean and second standard deviation of pixel values corresponding to the second object in the second image;
- determine a threshold by determining a second number of second standard deviations below which the second mean of pixel values corresponding to the second object occurs;
- and
- determine an object status as one of a real object or a counterfeit object by comparing the first measure of pixel values based on the first object to the threshold.
