In R2012a, we introduce CIRCULAR HOUGH TRANSFORMS for detecting circles in images. There are several parameters which can be manipulated to enhance the performance of the IMFINDCIRCLES functionality. This app provides an interactive environment for changing parameters and options, and for visualizing immediately the effects of the calculation.
USAGE:
circleFinder launches the GUI environment with the default image ('coins.png') pre-loaded.
circleFinder(inputImage) sllows user to specify input image, or the name of an input image.
CLASS SUPPORT:
inputImage can be any valid image format readable by IMREAD. Color (RGB) images are supported, but circle detection is performed on the RGB2GRAY representation.

(See help for IMFINDCIRCLES for details.)

NOTE: This function and app are verified for R2014b readiness, and are intended as REPLACEMENTS FOR FindCirclesGUI.

2.0.0.1

Updated license
2.0.0.0

I think I still had some incompatibilities with newer (R14b+) MATLABs. This should fix them.
Modifying description to include link to instructional YouTube video.
1.9.0.0

Verified for R2014b readiness. I think it should still work in previous versions.
1.8.0.0

Fixed a problem with underscores in image names, and with loading subsequent images.
1.7.0.0

Incorporates a missing file that disallowed loading new images. Also fixes a problem with underscores in image titles.
1.6.0.0

Now defaults to "process immediately" = false. Also, takes optional input argument specifying initial radius range. A few minor bug fixes, better expandAxes behavior, better image import behavior.
1.5.0.0

Updated to include an App file for R2012b.
1.4.0.0

Steered to correct files.
1.2.0.0

Adding copyright.
