...In addition to the ellipticity, rectangularity, and triangularity measures tw o sets of moment invariants were considered (those invariant to similarity transforms as well as affine invariants), and the standard shape descriptors of eccentricity, circularity, compactness, and convexity [10]....

...Given these difficulties, a popular approach is to design shape descriptors sensitive to specific aspects of shape suc h as eccentricity, Euler number, compactness, and convexity [10]....

...Peripheral blood vessels and perforating arteries should be excluded from CTP maps because they may mimic areas of falsely high perfusion within brain tissue.(22) Kudo et al (2003)(24) evaluated the efficacy of vascular pixel elimination in CTP imaging in comparison with positron-emission tomography (PET)....

...Gray matter typically measures 30 – 40 HU and white matter, 20 –30 HU; removal of pixels 0 HU or 60 – 80 HU effectively eliminates bone, fat, and air from unenhanced CT images.(22) Alternatively, thresholds can be based on the actual parametric map values....
