Description
Dear users!
While analyzing the face image (face tracking), it has been observed that standard face tracking algorithms sometimes find it where it is not. The contours of the face appear for a moment in places of the frame where there is no image of the person's face. I thought it was an algorithm error. And in many cases it is. BUT!!! Once I tried to talk to that ghostly outline of a face. I asked him to freeze. He froze, i.e. the contour ceased to disappear. Then I asked him to open his mouth. Contour opened his mouth. Asked to nod to the left, he nodded.... Theoretically, it could be a coincidence, but it is very unlikely. Decided to share this with You. Made this program. It contains only the algorithm of tracking a person's face and an additional service. Namely: • Face tracking during camera operation. • Switch camera from front to selfie. • The ability to record video, as in the standard camera program, but there is a choice to write with or without contour. • The ability to take photos, but there is a choice with or without contour. • View captured video or photo and search for Ghost faces in it. Videos or photos can be taken either by this app or by any other. • Share your findings with friends. By sending them from the app with the standard "Share" service. • Receive from friends their videos and photos and analyze them using the app.
In Pro version: • Detector type selection: - basic face detector; - the second face detector from the Dlib library; - cat detector. • Adjustment of the sensitivity of all types of detectors; • Setting the type of output of the face contour.
There are no connections to any server (except Unity ADS), no logins, no hidden sending of information. The application uses: • the camera only for shooting at the tracking entity (Ghost or spirit); • memory for recording and playing photos and videos;
For those who are interested in what technologies and algorithms the application uses, here they are: Unity3D, openCV, cascade haara, dlib. These technologies are used in many currently popular applications of overlay masks on the face.
Some limitation. • The algorithm sees faces looking directly into the camera, or at an angle of no more than 20°. Ie ghosts, not looking at the camera he will not see. • The algorithm spends a lot of CPU resource and can slow down on external (recorded) large videos and photos. But it still analyzes every frame, just in slow motion.
Be patient, ghost faces may not be find for a long time.
A successful search. With respect, Michael Frankel
P. S. Perhaps this is an error of the algorithm. The program does not claim to be scientific. It's more like a joke....

If this game developed into a body tracking algorithm app that detected bodies of actual beings such as furries/extraterrestrial beings, including many other things related it would be a spectacular app. Very neat idea here...

This is the real deal because 8 had another app that said that there are two ghosts in my room a Male and a female and the app showed me two faces

This app is really good for ghost hunting. I waved at the face and it smiled! I do believe in that it detects ghost. Great app! At least I found out that my spirit is friendly. If I had two spirits that would be a different story.

I was going to give u 5 star 🌟 but as video Disappeared and so many ads I work hard recording because of adds now video are gone 😒 So might want fix it or something Try to get video on phone 📱 I'm disappointed

I can't believe people actually think this is real. It doesn't work in a dark room. With the lights on you see faces just about anywhere. Turn the lights off and all faces disappear.

Scam, you ask spirits to let you know that they are there by asking go to a specific place for proof and don't show. You just move phone around and it the faces just go wherever you aim to or faces always stay in the same location when you move the phone back. It's a fake app more like a game app just to get you excited for nothing or think it's really legit. Waste of time

When I open the app, and I clicked on the ghost face detection camera it lagged my phone really bad and the app crashed please fix
