示例1: MatchingStrokeWidth
// Returns true if other has a similar stroke width to this.
bool BLOBNBOX::MatchingStrokeWidth(const BLOBNBOX& other,
double fractional_tolerance,
double constant_tolerance) const {
// The perimeter-based width is used as a backup in case there is
// no information in the blob.
double p_width = area_stroke_width();
double n_p_width = other.area_stroke_width();
float h_tolerance = horz_stroke_width_ * fractional_tolerance
+ constant_tolerance;
float v_tolerance = vert_stroke_width_ * fractional_tolerance
+ constant_tolerance;
double p_tolerance = p_width * fractional_tolerance
+ constant_tolerance;
bool h_zero = horz_stroke_width_ == 0.0f || other.horz_stroke_width_ == 0.0f;
bool v_zero = vert_stroke_width_ == 0.0f || other.vert_stroke_width_ == 0.0f;
bool h_ok = !h_zero && NearlyEqual(horz_stroke_width_,
other.horz_stroke_width_, h_tolerance);
bool v_ok = !v_zero && NearlyEqual(vert_stroke_width_,
other.vert_stroke_width_, v_tolerance);
bool p_ok = h_zero && v_zero && NearlyEqual(p_width, n_p_width, p_tolerance);
// For a match, at least one of the horizontal and vertical widths
// must match, and the other one must either match or be zero.
// Only if both are zero will we look at the perimeter metric.
return p_ok || ((v_ok || h_ok) && (h_ok || h_zero) && (v_ok || v_zero));
