Hi,
is there a way to save informatiom about a detected face in a picture? I want to find a face on a picture, then search same images files and try to find files, where the initialimage was found too. |

"an algorithm may analyze the relative position, size, and/or shape of the eyes, nose, cheekbones, and jaw. These features are then used to search for other images with matching features"
This is what i mean in fist entry. The information for comparing. Without this i can't use face detection, because it is only an nice feature i can't use. Why should i detect a face without the feature to compare? |

Wikipedia has an article about facial recognition techniques at http://en.wikipedia.org/wiki/Facial_recognition_system

Try it. First load an image with many persons and try to find yourself. After found, load many imagefiles and try to find the files, where your person/your face is in, too.
To do this, you have to do:
- Extract all persons from initial image file and get data of yourself
- Then load all other files and extract every person on each imagefile
- Compare each person with the initial image
This doesn't work. You never find other images, if you, for example, look to left or look to right instead of looking into the same direction like in initial imagefile. |

Sorry, it is still not clear for me. What do you mean for "face information"? |

I need face information to find out, where this face can be found in other image files. Currently i need to
1. Extract all faces
2. Load other file
3. Extract all faces
4. Compare each Face (from 3) with 1
This doesn't work fine, because face (from 1) is never exact the same position on the other picture. So i think i need a key to compare. |

Hi,
do you want to save the coordinates of the face bounding box or the face bitmap? |
