2015-12-16 05:11:29 -0600 | commented question | How to convert detected mouth region in gray-scale and binary in android ? yes i can see the normal mouth ROI i draw a rectangle around the mouth area |
2015-12-16 05:02:27 -0600 | commented question | How to convert detected mouth region in gray-scale and binary in android ? No it doesnot show grayscale region... but when i tried this it show me region in blue.. it means only grayscale is not working |
2015-12-16 04:42:31 -0600 | commented question | How to convert detected mouth region in gray-scale and binary in android ? @Pedro Batista i have spent 2 days but nothing works :( i want only a region to be in grayscale for further processing... i have seen opencv4android mixed processing project sample but there is no code for showing a ROI in grayscale |

2015-12-07 09:15:52 -0600 | commented question | How to use detectMultiScale detector for ROI in Face detection. Please help me in this code. Mat mouthROI = mGray.submat(moutharea); i think we are doing this wrong we should take this moutarea from the detected face not from whole mGray ... what do you think |
2015-12-07 09:02:46 -0600 | commented question | How to use detectMultiScale detector for ROI in Face detection. Please help me in this code. but when i try this code: it shows the red rectangle on lower portion for each detected face |
2015-12-07 08:56:30 -0600 | commented question | How to use detectMultiScale detector for ROI in Face detection. Please help me in this code. i tried this ... it only shows simple face detection |
2015-12-07 08:21:02 -0600 | commented question | How to use detectMultiScale detector for ROI in Face detection. Please help me in this code. do we need to extract the lower portion area from detected face and save it as an image and then apply the multiScaleDetector only on that image? |
2015-12-07 08:19:14 -0600 | commented question | How to use detectMultiScale detector for ROI in Face detection. Please help me in this code. i tried the code but it does not work.. i am extracting the lower portion of face (as mouth position is at the lower side of face ) by using this: Rect moutharea = new Rect (r.x , r.y+(r.height * 2/3), r.width,r.height/3 ); after that i am passing this lower portion which is "moutharea" in my case to MAT mouthROI by using this Mat mouthROI = mGrey.submat( moutharea ); then i want to detect the mouth in this mouthROI by using mJavaDetectorMouth.detectMultiScale(mouthROI , mouth, 1.1, 2, 2, // TODO: objdetect.CV_HAAR_SCALE_IMAGE new Size(mAbsoluteFaceSize, mAbsoluteFaceSize), new Size()); everything seems perfect... but i dont know why it is not working.... |

2015-12-07 00:25:08 -0600 | asked a question | How to use detectMultiScale detector for ROI in Face detection. Please help me in this code. i am using this open cv 3.0 sample project of face detection. i am writing code for my android application. I have change the code for mouth detection on face. After detecting the face i am getting MOUTH region from FACE. but when i pass the argument "moutharea" to "detectmultiscale " it is showing me this error "The method detectMultiScale(Mat, MatOfRect, double, int, int, Size, Size) in the type CascadeClassifier is not applicable for the arguments (Rect, MatOfRect, double, int, int, Size, Size)" |
