Even using polygon annotation, the efficiency of pixel labeling will still be very low due to various scales and shapes of the polygons, the unclear criterion how small a region can be ignored, and some regions with uncertain labels.
Although we usually accomplish pixel labeling by drawing a polygon on the image to annotate a region composed of pixels with the same class and fill it with a certain color, several factors will still make pixel labeling a hard and laborious task, such as various scales and shapes of the polygons, the unclear criterion how small a region can be ignored, and some regions with uncertain labels.
Elijah finds the increasingly unclear criteria understandably baffling: "I'm just not sure what the Mobos is, basically – looking down the categories, at these totally contrasting styles, it's so vague it's meaningless.
Competitive markets constitute the default setting of the system even though the evidence base for this is, at best, flimsy: the "burden of proof" lies on other approaches to demonstrate (against unclear criteria) why and how an alternative model could be preferable.
Faculty members were unclear how to provide a proper assessment for students given the cultural differences between instructors and students, as well as unclear criteria for how to handle these differences.

Concerning the species Protiara tetranema, recorded by Pell (1918, 1938) from the Adriatic Sea, based on unclear criteria, Schuchert (2009) suggested that it is a doubtful, unrecognizable species.
However, in Malawi, where DHMT members described a context that lacked a systematic, accountable supervision structure, with unclear criteria and assumed expectations of staff performance, supervision practice was dependent on the attitudes and priorities of supervisors.
However, such lists have been limited by unclear criteria for which recognized carcinogens should be considered occupational carcinogens, and by inconsistent and incomplete information on the occupations and industries in which the carcinogenic substances may be found and on their target sites of cancer.
In light of our three-fold distinction, it is manifestly unclear what criterion his observers should use to define the "best combination".
However, the optimal methods of detecting antibody and criteria for seropositivity to H7 virus in humans remain unclear; current criteria used are those established and adapted by the WHO for H5N1 subtype human infection and extrapolated for the H7 subtype.
