object detection using opencv source code

Sometimes I will go and see some of the foreign Daniel's Code , And learn, reference, and lament that the big bull is the big bull, the gap is not a little bit, but also a little sigh of slowly pull up and the distance between the big bull. Actually learning Daniel Source code It is a very good progress and can give you a new perspective. Seeing this big bull's

Finally summon up the courage to see Hough Transform source code, before I also blindly wrote a detection oval center of the =_=!

In the previous Silverlight, there was an hittest method that could be used to perform collision detection. But, older versions (pre 3.0) did have a hittest method! The hittest method cannot be used in silverlight4. So what should we do? Next I will explain a foreign Source code To let everyone know how to perform collision

Later, we will analyze the differences between methods (1) and methods (3.Tutotials also provides the time comparison of the above three methods.

Next, we will ans

The current asynchronous mode allows the possibility of the error data to be returned during the period. Reference Documentat

I 've been learning from the previous article for a long time. I analyzed the source code of calcHist, but I didn't quite understand it in some places. I 've been busy with graduation and have not continued, however, I always felt that something was not completed. In the past two days, I sorted out the source code of t
