Patent ID: 8553945

Claim:
A method of evaluating two bi-chrome digital images generated by an imaging device, the method comprising: generating a first image, the first image having pixels of a first color and a second color; identifying, using a processor, a particle comprising contiguous pixels of the first color in the first image; determining, using a processor, first information relating to particle size and particle location of particles of the first color contained in the first image; generating a second image, the second image having pixels of the first color and the second color; identifying, using a processor, a particle comprising contiguous pixels of the first color in the second image; determining, using a processor, second information relating to particle size and particle location of particles of the first color contained in the second image; developing, using a processor and the first information, a first value corresponding to the area of the first image covered by particles of the first color; developing, using a processor and the second information, a second value corresponding to the area of the second image covered by particles of the first color; and determining, using a processor, if the second image is acceptable based on a predetermined objective criteria and the first and second values.
