Long Distance Heterogeneous Face Database (LDHF-DB)


LDHF database contains both visible (VIS) and near-infrared (NIR) face images at distances of 60m, 100m, and 150m outdoors and at a 1m distance indoors. Face images of 100 subjects (70 males and 30 females) were captured; for each subject one image was captured at each distance in daytime and nighttime. All the images of individual subjects are frontal faces without glasses, and collected in a single sitting.

Short distance (1m) visible light images were collected under a fluorescent light by using a DSLR camera with Canon F1.8 lens, and NIR images were collected using the modified DSLR camera and NIR illuminator of 24 IR LEDs without visible light. Long distance (over 60m) VIS images were collected during the daytime using a telephoto lens coupled with a DSLR camera, and NIR images were collected using the DSLR camera with NIR light provided by RayMax300 illuminator.
