Patent ID: 8565492

Claim:
A method of evaluating a bi-chrome digital image generated by an imaging device, the method comprising: generating an image with a hand-held imaging device, the image having pixels of a first color and a second color; dividing, using a processor, the image into a first area corresponding to a portion of the image and a second area corresponding to a portion of the first area of the image; determining, using a processor, particle information relating to particle size and particle location of particles of the first color contained in the image, each particle comprising contiguous pixels of the first color; determining, using a processor and the particle information, a first value corresponding to the total number of pixels which are contained in particles of a first size in the first area; determining, using a processor and the particle information, a second value corresponding to the total number of pixels which are contained in particles of a second size in the second area, wherein the particles of the second size include particles of the first size; and determining, using a processor, if the image is unacceptable based on predetermined objective criteria and the first and second values.
