How can I use OpenCV for face detection?
You can perform fast, accurate face detection with OpenCV using a pre-trained deep learning face detector model shipped with the library. You may already know that OpenCV ships out-of-the-box with pre-trained Haar cascades that can be used for face detection…
Can OpenCV’s Haar Cascades detect my face?
OpenCV’s Haar cascades are notorious for missing faces that are not at a “straight on” angle, but by using OpenCV’s deep learning face detectors, we are able to detect my face. And now we’ll see how another example works, this time with three faces:
How do you detect a face in Python?
Detecting a face. After we decided to make use of Python, the first feature we would need for performing face recognition is to detect where in the current field of vision a face is present. Using the OpenCV library, you can make use of the HAAR cascade filters to do this efficiently.
Did you know Rybnikov’s deep learning face detector is included in OpenCV?
However, what most OpenCV users do not know is that Rybnikov has included a more accurate, deep learning-based face detector included in the official release of OpenCV (although it can be a bit hard to find if you don’t know where to look). The Caffe-based face detector can be found in the face_detector sub-directory of the dnn samples:
Is there an example of face detection in Objective-C?
Here’s a link that has an example using Core Image face detection from a live video feed. It’s from iOS 5 days, so it’s obviously both dated and in Objective-C, but if you’ve worked with CI before, you could probably translate it.
What are some real-time applications of face detection?
Face detection has rich real-time applications that include facial recognition, emotions detection (smile detection), facial features detection (like eyes), face tracking etc. You can also explore more exciting machine learning and computer vision algorithms available in OpenCV library.
