| 2013-07-02 11:30:20 -0600 | commented answer | How does cvhaardetectobjects c2g works than you all for the answers. i use the c api because i already know it and i can't spend so much time to learn the cpp api now. as i've understood the function uses one channel of the image. what i son't understand is how the iplimage where i load my images (and can load any type of image) became a 1 channel immage when sent to the function for detection. |
| 2013-06-12 04:53:17 -0600 | asked a question | How does cvhaardetectobjects c2g works i'm doing some experiments with violajones algorithm for my digital imaging university course. i need to know how the CvHaarDetectObjects() function, that receives in input a color image, transforms it in a grey scale image. i can't find this information in the documentation and it's hard to find it in the code. thanks in advance Antonio Castellano |
