williamcoral: hola, podrias compartir el codigo de tu programa	VickyView: yeah
bbanko100: yes, makes sense. i will check the opencv2.0 samples c squares.c thanks.	ricmcm88: continue... its maximum area is less than 40 of the total area of capture, thus preventing a square detect larger area that were involved in the edges of the frame. you can see an example: opencv2.0 samples c squares.c some cv methods: find contours: cvfindcontours poly aprox: cvapproxpoly get area: cvcontourarea check convexity: cvcheckcontourconvexity sorry for my english :
ricmcm88: thanks the idea is to find all contours. for each of them performs a simple polygon approximation. contours will apply those whose sides are horizontal, vertical or diagonal lines. the next step is check the polygons that meet the following characteristics: with 4 sides that is convex closed polygon . the angle formed by any of its vertices is greater than a minimum angle in my case 53 its area is greater than areamin deleting the squares are too small .	bbanko100: very nice bravo. could you write some info about how you solved the rectangle detection. i've created this solution: youtube.com watch v xuch8lolnjy and the most difficult part was to detect the rectangle. in general, your project would be a very very good opencv tutorial.
