About dataset

We annotate 27attributes for Market-1501. The original dataset contains 751 identities for training and 750 identities for testing. The attributes are annotated in the identity level, thus the file contains 28 x 751 attributes for training and 28 x 750 attributesfor test, where the label "image_index" denotes the identity. The annotations are contained in the file market_attribute.mat.

The 27 attributes are:

attribute representation in file label
gender gender male(1), female(2)
hair length hair short hair(1), long hair(2)
sleeve length up long sleeve(1), short sleeve(2)
length of lower-body clothing down long lower body clothing(1), short(2)
type of lower-body clothing clothes dress(1), pants(2)
wearing hat hat no(1), yes(2)
carrying backpack backpack no(1), yes(2)
carrying bag bag no(1), yes(2)
carrying handbag handbag no(1), yes(2)
age age young(1), teenager(2), adult(3), old(4)
8 color of upper-body clothing upblack, upwhite, upred, uppurple, upyellow, upgray, upblue, upgreen no(1), yes(2)
9 color of lower-body clothing downblack, downwhite, downpink, downpurple, downyellow, downgray, downblue, downgreen,downbrown no(1), yes(2)

Note that the though there are 8 and 9 attributes for upper-body clothing and lower-body clothing, only one color is labeled as yes (2) for an identity.



To evaluate, you need to predict the attributes for test data(i.e., 13115 x 12 matrix) and save them in advance. "gallery_market.mat" is one prediction example. Then download the code "evaluate_market_attribute.m" in this repository, change the image path and run it to evaluate.
