In this paper, all available object detection techniques are categorized into background subtraction, optical flow and spatio-temporal filter methods.
In internal cohort analyses, serum TCDD levels were extrapolated to the end of service in Vietnam assuming a constant half-life of 7.6 years, and categorized as "background" (≤10 ppt), "low" (>10 ≤118.5 ppt), or "high" (>118.5 ppt) [ 63].
In a 1999 study, Ranch Hands were classified according to serum TCDD levels measured in 1987 (for most subjects) or 1992, extrapolated to the end of military service in Southeast Asia under the assumption of a constant half-life of 8.7 years, and categorized as "background" (≤10 ppt), "low" (10 ≤94 ppt), or "high" (>94 ppt) [ 64].
Participants subsequently learned to categorize novel background colors (ie, generalization contexts) as being similar to either the unpredictable or predictable pain context.
Background PM10 associated with background NOx categorized the primary contribution.
Students born in the country of survey were categorized as having immigrant background if both their parents were foreign born.
Approximately 1000 anti-genomic probes were used for background subtraction, categorized by GC count.
Ethnic background was categorized as Caucasian, Native American Indian (from both parents), African American, and others.
Individuals with Italian background were categorized by nationality, country of birth and language.
Ethnic background was categorized as Caucasian, Native American Indian (from both parents), African American, or others.
