Is there any method to dectecting face using emgu cv from just image? I'm not looking using color segmentation method or from motion detect method
You can use Haar Cascade Classifier Classifier. Here an example http://ahmedopeyemi.com/main/face-detection-and-recognition-in-c-using-emgucv-3-0-opencv-wrapper-part-1/.
And here a good (and concise) explanation on how HCC works and how to train your own classifier (for face detection you can find several good classifiers ready to use) http://docs.opencv.org/trunk/d7/d8b/tutorial_py_face_detection.html
