However, previous studies have employed region-of-interest approaches or have used small or unmatched samples, with a consequent risk of type II error.
Figure 1 illustrates the working model of a biometric system that employs region around the eye (periocular region) as a trait for recognition.
It should be noted that geographic variation in regional climates is internally controlled in the extreme heat event measure, which employs region-specific temperature thresholds (i.e., the 85th percentile of a long-term temperature trend for each metropolitan statistical area) to identify extreme temperature episodes.
Another method presented for retinal vessel segmentation[34] employs region-based level sets and region growing approaches, simultaneously.
16 For this and similar endpoints, logistic regression models were employed including region and baseline DAS28 or the respective baseline values (eg, CDAI or radiographic scores), with supportive Cochran Mantel–Haenszel tests stratified for the same parameters.
Previous studies on Japan, such as that of Kagawa et al. (2007) and Kagawa and Kondo (2007) employed nine regions.
In particular, the following selection criteria, previously used in the CHAOS-4 model (Olsen et al. 2014), have again been employed: Dark regions only (sun at least 10° below the horizon).
The perimeter, distance from the origin, angle (degrees), shape and x/y-coordinates of the centroid of the cluster are determined using the same methods employed for regions.
Moreover, we will also employ the region attributes of images to revise the incorrect recognition of classifiers relying on visual features.
The percentage of mitotic cells was calculated by employing a region as shown in Figure 2 (labelled M).
