Tutorial for iPhone OpenCV on shape recognising [c

问题:

I will like to do some iPhone OpenCV application to recognize simple shapes like square through camera.

Can anyone show me a simple tutorial for it?

Before jumping on iPhone development with OpenCV make sure you master OpenCV on a standard platform, like Windows/Linux/Mac OS X.

Also, decide which interface of OpenCV you prefer to use: C or C++

There are the results I got from using the search box on stackoverflow:

Detecting a circle of a specific color (or gray level) with openCV

Detect Corners of Triangle in Image on iPhone

OpenCV Object Detection - Center Point

How to recognize rectangles in this image?

and these are results from Google:

Tracking colored objects in OpenCV

Circle recognition using openCV

Fast OpenCV Circle Tracking (check the description of the video for tips)

This series for OpenCV is great, specially this one: Vision for Robots 5 of n: Hough Transform
