Claim 8:
9. A non-transitory machine readable medium having stored thereon instructions for estimating target object dimensions within digital images comprising executable code that, when executed by one or more processors, causes the one or more processors to:
obtain a digital image containing a target object and a first reference object having a first fiducial pattern having a highly saturated color, wherein the first reference object further has at least one of:
an optical transmittance between about 2 percent and about 80 percent,
a reflectance between about 15 percent and about 85 percent,
a diffuse transmittance between about 5 percent and about 65 percent, or
a direct transmittance less than about 10 percent and another diffuse transmittance greater than the direct transmittance;

locate the first reference object in a digital image;
calculate a pixel scale factor for the digital image based on both measured and known dimensions of the first reference object;
locate the target object in the digital image; and
calculate a dimension of the target object based on the pixel scale factor.
