Description

Running squares_ocl on CPU triggers a bug.

./squares_ocl

A program using OCL module pyramid scaling, Canny, dilate functions, threshold, split; cpu contours, contour simpification and
memory storage (it's got it all folks) to find
squares in a list of images pic1-6.png
Returns sequence of squares detected on the image.
the sequence is stored in the specified memory storage
Call:
./squares
Using OpenCV version %s
2.4.9
