BaseRht

A template that bootstraps a full Randomized Hough transform implementation. The basic primitives required are as follows.

Types: Curve and Key tuples that define curve parameters and accumulator key for the curve. Functions: curveKey - accumulator key for a curve, onCurve - test if a point is on curve, fitCurve - fit a curve to a given random access range of points.

mixin template BaseRht () {

alias This = typeof(this);

alias Point = Tuple!(int, "x", int, "y");

static auto toInt(double a);

static bool isInvalidCurve(Curve c);

ref threshold(int threshold);

ref epouchs(int epouchs);

ref iterations(int iters);

ref minCurve(int minimalCurve);

static auto opCall();

auto opCall(Slice!(kind, [2], T*) image);

auto opCall(Slice!(kind, [2], T*) image, Range points);

struct RhtRange(T, SliceKind kind, P);

}
