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 GUI provides an interactive GUI for changing parameters and options, and for visualizing immediately the effects of the calculation.
FindCirclesGUI launches the GUI environment with the default image ('coins.png') pre-loaded.
FindCirclesGUI(inputImage) sllows user to specify input image, or the name of an input image.
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: I assume that the interactive GUI is pretty self-explanatory. Please share any questions, concerns, or suggestions with me.
