A Dataset of Ecological Images for Automatic species-identification of Butterflies

However, all the available datasets used for the studies of butterfly auto-identification are based on specimen images, and lack of ecological butterfly images. Therefore we set up a dataset of butterfly images from the ecological environment in China and the corresponding annotation files in PASCAL VOC 2007 format.

The dataset contains 721 butterfly images, covering 94 butterfly species. Each image corresponds to an annotation file, which contains the size of the image, the taxonomic information and the location of the butterfly in the image. This dataset could support researches on automatic recognition, object detection, and insect taxonomy.
