This image shows a sample face rectangle automatically detected using our face detector. In contrast, our search engine finds good results because our system has labeled each face using our attribute classifiers offline. All elements are separated by tabs. Note the complementary performances of both Adaboost methods versus the full-face SVM method for the different attributes, showing the strengths and weaknesses of each approach. Each of the 15, faces in the database has a variety of.

At search time, only this attribute database needs to be searched, resulting in real-time searches.
CAVE | Projects: FaceTracer: A Search Engine for Large Collections of Images with Faces
This contains all of the above files in a zip file, for ease in downloading. Thus, our search engine can be a useful addition to existing personal photo management software by allowing people to easily organize their photos on the basis of the faces within them. In contrast, our search engine finds good results because our system has labeled each face using our facetracfr classifiers offline. Our search engine owes its superior performance to two main factors: Our feature selection process automatically selects one or more feature types from these options.
The letters in parentheses denote the code letter for the region, used as a shorthand notation for describing dtaabase feature combinations. Public Figures Face Database. This can be used to analyze the webpage and its links to obtain more information about the images.
These labels were assigned manually by a group of people, and then manually verified by a single person to ensure consistency. Each of the 15, faces in the database has a variety of metadata and fiducial points marked. These images have been downloaded from the internet, and exhibit a large amount of variation -- they are in completely uncontrolled lighting and environments, taken using unknown cameras and in unknown imaging conditions, with a wide range of image resolutions.
In rare cases, a different image might be put up at the same location as an image from our dataset.
A key aspect of this work is that classifiers for new attributes can be trained automatically, requiring only a set of dattabase examples. A large and diverse dataset of face images with a significant subset containing attribute labels.
A simple python script that demonstrates how to parse the dataset and display information about a particular face in the dataset. Our feature selection process automatically selects features from our set of 10 regions.
CAVE | Databases: FaceTracer Database
It describes the database creation process and shows several example queries. Yet, the flexibility of our framework does not come at the cost of reduced accuracy -- we compare against several state-of-the-art classification methods and show the superior classification rates produced by our system.
It would be impossible to define all of these manually for each attribute and maintain our high accuracies. faccetracer
A scalable and fully automatic architecture for attribute classification. Faces in our database have been extracted and aligned from images downloaded from the internet using a commercial face detector, and the number of images.
Since it is composed of real-world images collected in the wild, it provides a much more representative sample of typical images than other, more controlled, datasets -- there is large variation in pose, environment, lighting, image quality, imaging conditions and camerasetc. The various metadata we offer for each face provides opportunities for comparison and evaluation of a large number of common vision tasks, such as face detection, fiducial point detection, and pose angle detection.
We have created the first face search engineallowing users to search through large collections of images which have been automatically labeled based on the appearance of the faces within them. This contains statistics for each face.

Note the complementary performances of both Adaboost methods versus the full-face SVM method for the different attributes, showing the strengths and weaknesses of each approach. This contains a list of all faces with image urls and page urls. Furthermore, it is easy to add new images and face attributes to our search engine, allowing for future scalability.

Our attribute-tuned global SVM performs better than prior state-of-the-art methods.
Each line contains a single face id, attribute name, and label, separated by tabs. The regions are large enough to be robust against small differences between individual faces and overlap slightly so that small errors in alignment do not cause a feature to go outside of its region. Furthermore, the vast majority of images on flickr are simply not tagged, making them "invisible" to search. Images are first downloaded from the internet and run through a face and fiducial point detector to extract the faces within them.
The face id uniquely defines a face, and these ids are the common element linking all the files. On the left is one region corresponding to the whole face, and on the right are the remaining regions, each corresponding to functional parts of the face.
