# Dataset Card for Birdsnap Dataset v 1.1. |
|
|
|
Welcome to the Birdsnap dataset, consisting of 49,829 images of 500 species of North American birds, collected from Flickr, and corresponding species, bounding box, and part labels. |
|
|
|
|
|
The dataset distribution also consists of the following files: |
|
|
|
1. species.txt |
|
This file lists the species in the dataset. The first line is a header. Each subsequent line represents a species. Lines are tab-delimited, and the fields |
|
are: |
|
- id: An integer id for the species. These ids run from 1 to 500 for the 500 species. |
|
- common: The common English name of the species, for example "Blue Jay." |
|
- scientific: The scientific (Latin) name of the species, for example "Cyanocitta cristata." |
|
- dir: The name of the a directory in which to store the images of this species. This is just the common name with spaces and other dangerous-in-file-path characters replaced or removed. |
|
|
|
2. images.txt |
|
This file lists the images in the dataset, with the coresponding bounding boxes, part locations, and species labels. Like species.txt, it is tab-delimited with the first line giving field names. The fields are: |
|
- url: The URL from which the image was downloaded. |
|
- md5: An MD5 sum of the image file constants. |
|
- path: The local path of the image. |
|
- species_id: The id of the species of the labeled bird in the image. |
|
- bb_x1, bb_y1, bb_x2, bb_y2: The coordinates of the top-left (bb_x1, bb_y1) and bottom-right (bb_x2, bb_y2) corners of the bounding box of the labeled |
|
bird. |
|
- ${part}_x, ${part}_y: The coordinates of part ${part}. Parts are back, beak, belly, breast, crown, forehead, left_cheek, left_eye, left_leg, left_wing, nape, right_cheek, right_eye, right_leg, right_wing, tail, throat. |
|
|
|
3. test_images.txt |
|
This file lists the 2443 test images used in the species identification experiments in the paper. It has a header line, then the "path" (from images.txt) of each test image, one per line. |
