face-detection

I have a very large photo gallery with thousands of similar people, objects, locations, things. The majority of the people in the photos have their own user accounts and avatar photos to match. There are also logical short lists of people potentially in the photo based on additional data available for each photo. I allow users to tag photos with their friends and people they know but an automated process would be better. I've used photo tagger/finder from face.com integrating with Facebook photos and the Google Picasa photo tagger for personal albums also does the same thing and is exactly

I am currently developing an iPhone app that makes use of a UIImagePickerController with a custom overlay to take photos. Unfortunately I do not have direct access to an iPhone 4S but several testers have reported that the camera picker is drawing a green border around faces exactly like this: http://cdn.iphonehacks.com/wp-content/uploads/2012/03/camera_faces.jpg Due to the nature of this app this is not desirable. A thorough search of the UIImagePickerController docs didn't turn up anything and similarly everything I could find on here relating to face detection was providing instructions in

I am working on application for finding face in 2D image and later inside same image I want to find mouth, but I have some problem right now. This is my code so far: for (int i = 0; i < faces.size(); i++) { Point pt1(faces[i].x, faces[i].y); Point pt2((faces[i].x + faces[i].height), (faces[i].y + faces[i].width)); rectangle(frame, pt1, pt2, Scalar(255,0 , 0), 2, 8, 0); //I WANT ROI(FOR MOUTH DETECTION) TO BE ONLY HALF OF THE RECTANGLE WITH FACE Rect mouthROI; mouthROI.x = (faces[i].x); mouthROI.y = faces[i].y*(1.5); mouthROI.width = (faces[i].x + faces[i].height); mouthROI.height = (faces[i].y

I'm trying face detection using OpenCv 2.3 . My trying to load "haarcascade_frontalface_alt_tree.xml" on my project , I'm constantly unable to load the xml file. CvHaarClassifierCascade * pCascade = 0; // the face detector const char* file ="C:\OpenCV2.3\opencv\data\haarcascades\haarcascade_frontalface_alt_tree.xml" ; pCascade = (CvHaarClassifierCascade*) cvLoad(file , NULL, NULL, NULL); if (!pCascade) { exit(-1); // unable to load xml } I believe that I'm expeiancing the same problem as this problem I have tried to load an image before the cvLoad command , but it didn't help. I'm using OpenCV

I'm working on an app in which i have to detect left eye, right eye, and mouth position. I have an imageView on my self.view and imageView contains a face image, now I want to get both eyes and mouth coordinates. I have seen 2-3 sample codes for this but all are approximately same in all codes we have to invert my view for matching the coordinates which I don't want because my view have some other controls. And one more thing they all are using UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"image.png"]]; but my imageView has frame and i cant init it with image

I need to color the skin of the face... How do i find the skin color? now i get the skin color by RGB pixel value ... Still i am facing the problem i was matching the color coordinates to match the skin by certain color range... but still some area of the face not fall in my range of colors then it is not color that area.. other than the face area may fall that region, that area also colored... Any idea about my issue... Thanks in advance.... MY code: -(void)colorImageBySliderValue:(float)value WithImage:(UIImage*)needToModified { CGContextRef ctx; CGImageRef imageRef = needToModified.CGImage;

I'm trying to implement the built-in iOS 5 face detection API. I'm using an instance of UIImagePickerController to allow the user to take a photo and then I'm trying to use CIDetector to detect facial features. Unfortunately, featuresInImage always returns an array of size 0. Here's the code: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage* picture = [info objectForKey:UIImagePickerControllerOriginalImage]; NSNumber *orientation = [NSNumber numberWithInt: [picture imageOrientation]]; NSDictionary *imageOptions =
