Families In The Wild (FIW) Database
FIW is the largest and most comprehensive database available for kinship recognition. FIW is made up of 11,932 natural family photos of 1,000 families-- nearly 10x more than the next-to-largest, Family-101 [7] database. Also, we have 656,954 image pairs split between the 11 relationship (see Figure 1), which is much larger than the 2nd to largest Kin-Wild II with 2,000 pairs for only 4 kinship types. For more information about FIW see [1].
The goal of kinship verification is to determine whether a pair of faces are blood relatives or not. This task has seen lots of attention, which mainly focus on parent-child pair-wise types-- father- daughter (F-D), father-son (F-S), mother-daughter (M-D), mother-son (M-S)-- though some have also focused on siblings pairs-- brother-brother (B-B), sister-sister (S-S). This challenge supports all prior pair-wise types in sets much larger than previously offered to the research community. In addition, we introduce grandparent-grandchild pairs for the first time-- grandfather-granddaughter (GF-GD), grandfather-grandson (GF-GS), grandmother-granddaughter (GM-GD), grandmother-grandson (GM-GS). As stated on the results page, our top performing benchmark scored an average accuracy of about 71%, so not only is there room for improvement, but also a need for more reliable systems before such technology is employed for practical purposes. This large-scale kinship verification challenge is made possible with the recently introduced FIW database. Kinship verification has the potential to improve social media tagging, ancestry/genealogy site suggestions, along with many other applications in technology and media.

FIW is made-up of 11,932 family photos that span 1,000 different families, with the data distributed fairly: an average of about 12 images per family, each with at least 3 and as many as 38 members. The FIW database is contains rich labels capturing the complex hierarchical relationships inherited throughout families (i.e., family trees).
