Detailed Description

template<typename T>
class TRTK::CorrelationSphere< T >

This class segment circles [or spheres] in 2D [3D] images. Just instantiate a class object, set your image and the radius range of the sought circles/spheres. After calling compute() the highest-weighted circle/sphere can be found either by calling findSingleSphere() or by searching the parameter space yourself. For the latter, getCorrelations() provides the vector of 2D [3D] images.

Computation time is linear in delta_r and dimensions d and superlinear [n*log(n)] in the number of pixels per dimension n.

Code Example (2D):

    // Construct a sample image & segment sphere out of it
    CImg<unsigned char> * im = new CImg<unsigned char>(128, 128, 1, 1, 15);
    cimg_forXYZ(*im, x, y, z){
        float dist = std::sqrt((x - 30)*(x - 30) + (y - 30)*(y - 30));
        if ((dist > 9.5) && (dist < 10.5))
            (*im)(x, y, z) = 255;
    }
    TRTK::CorrelationSphere<unsigned char> correlation = TRTK::CorrelationSphere<unsigned char>(im);
    delete im;
    correlation.compute();
    TRTK::Sphere sphere = correlation.findSingleSphere();
    std::cout << QString::number(sphere.x).toStdString() << " " << QString::number(sphere.y).toStdString() << " " << QString::number(sphere.z).toStdString() << " " << QString::number(sphere.radius).toStdString() << " " << std::endl;

Expected output:

30 30 0 10
