I have been working on an app for my science project. The app is using OpenCV to apply a Haar Cascade to an image, and draw a shape around the recognized object. However, I have been having some trouble with using the cv::CascadeClassifier to apply the Haar Cascade to my image. My project is an XCode Project using Swift. It uses a bridging header to utilize OpenCV with Swift. I am using OpenCV 3.0.0, downloaded from http://opencv.org. My code is located at https://github.com/adiprad/iOS-OpenCV-FaceRecognition. I am applying the Haar Cascade in OpenCVWrapper.mm. Here is the log while the app is running. Feel free to compile and test it on your device.
It would be greatly appreciated if someone could respond as soon as possible.
