ILSVRC is a well-known challenge that evaluates algorithms for object localisation and/or classification with the large-scale benchmark (i.e. ImageNet dataset).
The Pascal visual Object Classes is a well-known challenge over the years and has finished in 2012. However, Pascal VOC 2007 is still adopted to evaluate the-state-of-arts in visual recognition.
A useful tutorial about large-scale visual recognition was held in CVPR2013 containing slides, codes, and references.
A useful tutorial about attribute learning for data sparsity problem was held in CVPR2013.
