faceDetectionToRoi function

RectF faceDetectionToRoi(
  1. RectF bbox, {
  2. double expandFraction = 0.6,
})

Implementation

RectF faceDetectionToRoi(RectF bbox, {double expandFraction = 0.6}) {
  final e = bbox.expand(expandFraction);
  final cx = (e.xmin + e.xmax) * 0.5;
  final cy = (e.ymin + e.ymax) * 0.5;
  final s = math.max(e.w, e.h) * 0.5;
  return RectF(cx - s, cy - s, cx + s, cy + s);
