Information
===========
This ZIP archive contains:
1. 832 images for ten butterfly categories (55-100 images per category), collected from Google Images and manually filtered.
2. Segmentation masks for each image
3. Textual descriptions for each butterfly category, obtained from http://www.enature.com/fieldguides/.


Images
======
The 'images' folder contains a total of 832 images for ten butterfly categories, in JPG format.
Naming convention: Each image's filename is prefixed with the category ID of the butterfly (001, 002, ..., 010) followed by the sequence number of the image within the category. 
For example, '005_0002.jpg' represents the second image of the butterfly category '005'.

The scientific (Latin) names of the butterfly categories are:
001: Danaus plexippus	
002: Heliconius charitonius	
003: Heliconius erato	
004: Junonia coenia	
005: Lycaena phlaeas
006: Nymphalis antiopa	
007: Papilio cresphontes	
008: Pieris rapae	
009: Vanessa atalanta	
010: Vanessa cardui


Segmentation masks
==================
The 'segmentations' folder contains segmentation masks of each image in PNG format with a bit depth of 1 (a binary image). Pixels with values 1 represent foreground pixels.
Please refer to our BMVC2009 paper for more details on how the segmentation masks were generated.


Textual Descriptions
====================
The 'descriptions' folder contains 10 text files, each containing the textual description for a butterfly category. 
The files are named according to the category ID of the butterfly (001, 002, ... , 010) -- see the "Images" section above.

Each text file contains three lines:
Line 1: Scientific (Latin) name of the butterfly
Line 2: Common (English) name of the butterfly
Line 3: Textual description of the butterfly from eNature.com
