Finding Circles in Images Using MATLAB

Circular Hough transforms detect circles in images. There are several parameters which can be manipulated to enhance the performance of the imfindcircles functionality. This video describes the use of the Circle Finder app, which provides an interactive environment for changing parameters and options, and can be used to immediately visualize the effects of the calculation

@Mervin: There are lots of approaches to detecting rectangles-- including using image morphology (e.g., openings, closings) with a rectangular structuring element; using blob analysis (in MATLAB, using regionprops), paring results by properties that reflect the parameters of target "rectangles"; using Hough lines with some geometric (parallel/perpendicular) constraints; using generalized Hough transforms; using corner detections followed by geometry constraints.... It's difficult to point to a generalized approach, and the best approach for a particular problem depends on the nature of the image, and the tools at your disposal.

It took some time to realize that the voice I heard was not text to speech synthesis.

Useful Tutorial. Could you guide me on how to find Rectangular Regions instead of circular regions?
