Wavelet-Based Circular Hough Transform

Helps finding circles of a particular radius in images. Should be cross platform, although I only tested it in OS X.

main.cpp Demonstration of how to find circles of a particular radius.

Accumulator class Accumulates votes for centers.

Image class Image IO using the PNG library.

Wavelet class Morlet wavelet kernels.

Convolution class Convolves images with kernels.

LocMax class Locates local maxima in the accumulator space.

*.png files Sample images.

WCHT.xcodeproj Xcode project file, in case you use Xcode. To compile on Terminal, type g++ *.cpp -o wcht -I/usr/local/include -L/opt/local/lib -lpng or similar, depending on where the PNG library is installed in your machine.
