We are making available a large newly collected dataset -Thangga- of RGB images with a large diversity of contents.
The Thangga dataset is divided into:
-
train data: starting from 746 high definition high resolution images we obtain corresponding low resolution images and provide both high and low resolution images for 2, 3, and 4 downscaling factors.
-
validation data: 100 high definition high resolution images are used for genereting low resolution corresponding images.
-
test data: 100 diverse images are used to generate low resolution corresponding images.
Thangka dataset has the following structure: 946 images divided into: 746 images for training, 100 images for validation, 100 images for testing.
Thangga forder structure is as follows:
