2014-12-03 21:19:02 -0600 | asked a question | Get the SIFT descriptor for specified point using OpenCV I want get the SIFT feature for specified points. These points is gotten by hand not by KeyPoint Detector. My question is: I only know the position of the points but have no idea about the size and angle value. How should I set this value? Here is my code: Should I set the size param of KeyPoint to 32 for 32x32 patch. Is this implementation reasonable? |

2014-11-13 01:32:15 -0600 | asked a question | how to calculate the detection confidence score for opencv detector I want to use FDDB to evaluate some face detectors including opencv. But FDDB's detection output file require: It include a detection_score part. But the opencv's detector have no output like this. How to output this? |
2014-10-22 03:49:40 -0600 | asked a question | opencv split vs mixChannels To separate hue channel from HSV image, here is the code using the mixChannels function: But I know split function can also do this: Is that OK? If these are the same, I think split method is more clean. Am I right? |

2014-07-29 21:27:25 -0600 | asked a question | how to handle occlusion for face recognition? If there some occlusion on face (such as sunglasses, mask, scarf), the recognition rate will decrease steeply? How to handle this case? I have do a survey, the PCA reconstruction method have been mentioned by some literature. I don't know whether or not this method is the state-of-the-art method. Is there other method for address occlusion problem? |

2014-04-09 01:17:33 -0600 | asked a question | any face landmark tracking algorithm recommendation? Is there some tracking alogrithm for face landmark tracking? |
2014-03-25 01:51:17 -0600 | asked a question | How can I use landmark tracking technology to stasm library? I am using stasm for face landmark detection. It works well for static images. But I want to add tracking algorithm to this library (such as Kalman Filter) to improve the detect effect for video sequence. How can I do this? Any suggestion? |
