Synthetic Contour Fragments
Listed in Borealis and Agri-environmental Research Data Dataverse — shown once because both records carry DOI 10.5683/sp2/ajlj91
Data set contains contours composed of co-aligned Gabor (contour) fragments embedded in a sea of similar but randomly oriented (background) fragments.
Description
Contours differ in the location, length (number of fragments), inter-fragment rotation and the Gabor fragments used in their construction. 64 Gabors Fragments, contours lengths of [1, 3, 5, 7, 9], beta rotations of 0, +-15 degrees are included. The dataset contains 64,000 training and 6,400 validation images.
Images are all 256x256 pixels. Each image is divided into a grid of 14x14 pixels. Each grid square contains a 7x7 Gabor fragment.

The center of middle square tile is aligned with the image center. This results in a binary label of size 19x19 of whether a grid square contains the center of a contour fragment.
