MSRA-CFW: Data Set of Celebrity Faces on the Web

Established: May 20, 2012


Dataset Descriptions

The dataset includes image URLs for 202792 faces. The labels of the faces are automatically generated by the algorithm in [1], with high accuracy. To facilitate downloading the images, we provide a number of URLs for the near-duplicates of each face. Besides, the thumbnail images and facial features(LBP)[2] are also provided for visualization and benchmarking purposes. Due to copyright reasons, we donnot provide the original web images.

In the dataset, the files for each person are put into the same folder under this person’s name. The files in each folder are categorized into four types:

(1) thumbnails: downsampled images for the faces. These are for visualization purposes only. Please note that each image contains only one face as detected by a face detector [3].

(2) info.txt: contains the “original web images” (OWI) for the thumbnail images. For each thumbnail, info.txt contains a line of metadata followed by a list of near-duplicate image URLs. The metadata consists of: the number of near-duplicate image URLs, the file name of the corresponding thumbnail and the URL of the OWI.

(3) feature.bin: contains LBP features for the faces. The file starts with two int32 variables indicating the total number of faces and the dimension of LBP features, followed by a byte buffer storing all the features (one face after another).

(4) filelist_LBP.txt: each line of this file contains a file name, corresponding to the order of the features in feature.bin. The following four numbers on each line are the location of the faces in the OWIs, where the thumbnails are down-sampled (left top right bottom), and the last two numbers are the size of the OWIs.
