2016-03-18 07:44:56 -0600 | answered a question | Camera not scanning face properly I suggest you first try your app on PC, rather than jumping to Android. The problems you face are common ones if you are using any of the OpenCV Face Recognition algorithms (LBPHFaces, FisherFaces, EigenFaces). Try using all of these. In your PersonRecognizer.java file, line 16, change createLBPHFaceRecognizer to createFisherFaceRecognizer or createEigenFaceRecognizer and see which works best for you. As per the face inside face problem, once you detect face, you can restrict the blobs according to its size(length, width, area). As for the beard part, try using other cascade classifiers. If not, create your own. Research on how you can improve the available techniques or implement another Face recognition algorithm. (Read related papers) |
2016-03-17 07:12:59 -0600 | answered a question | How to detect the Licence plate? Turns out, the number plate is not actually white. I tuned the HSV parameters a little bit and it worked. Also, this is not a reliable method for detecting number plates. Since, it changes from image to image. |
2016-03-17 06:38:08 -0600 | answered a question | Moving object classification The aspect ratio of cars and moterbikes may be relatively less. But, cars will have more width (and length) You can check the length and width of each blob and set a threshold to classify the vehicles. Also, you can check the blob properties in an ROI (the junction) to make it more effective. The blob area and aspect ratio wouldn't vary that much within the ROI |

2016-03-06 23:55:22 -0600 | commented answer | How to use #include cvcam.h in opencv 3.0? If you just want to run it, then this code will directly run with OpenCV 3.0.0. But using the depreciated C functions is not recommended. Also, I think the problem is in including the libraries. How are you compiling this? If you are using Visual Studio in Windows, then follow this tutorial to compile. |
2016-03-05 03:36:21 -0600 | answered a question | How to reduce false positives for face detection One method for avoiding false positives might be to check for the size of the detected blob, or to check its aspect ratio. Faces must have a particular aspect ratio and thus eliminates false positives |
