title: getTickCount time unit confusion
body: <p>At the answer to the <a href="https://stackoverflow.com/questions/13031357/opencv-mat-processing-time/13187332#13187332">question</a> on Stack and in the book at <a href="http://www.google.co.in/url?sa=t&amp;rct=j&amp;q=opencv%20cookbook%20pdf&amp;source=web&amp;cd=1&amp;cad=rja&amp;ved=0CCwQFjAA&amp;url=http://lecture7.tistory.com/attachment/cfile24.uf@15094C4E512B0E4920B7B2.pdf&amp;ei=AiGBUdzaM8TKrAed8oHIBA&amp;usg=AFQjCNGpR1lRxZeLWX7XACC9_6th1n--aQ&amp;bvm=bv.45921128,d.bmk" rel="nofollow noreferrer">here on page 52</a> I found the normal getTickCount getTickFrequency combination to measure time of execution gives time in milliseconds . However the <a href="http://opencv.willowgarage.com/documentation/cpp/utility_and_system_functions_and_macros.html#cv-gettickcount" rel="nofollow noreferrer">OpenCV website</a> says its time in seconds. I am confused. Please help...</p>
