Aff-GTSRB & Proj-GTSRB

About DatasetAff-GTSRB and Proj-GTSRB are groups of datasets that were created to evaluate GTSRB models robustness for recognizing affine and projective deformations across different severity levels, were obtained from original GTSRB Test samples by view point angle variations (elevation and azimuth) and the two groups differ in terms of camera projection (orthographic and perspective), respectively.The Aff-GTSRB and Proj-GTSRB were derived similarly, with each dataset subgroup stemming from the original GTSRB Test samples and categorized according to four elevation angles: 90º, 60º, 45º, and 30º. Each subgroup was further subdivided into eight partitions according to the following azimuth angle variations: 0º, 15º, 45º, 60º, 90º, 120º, 190º, and 275º. Consequently, each new dataset (saved in an elevation folder) produced a total of 12, 630 × 8 = 101, 040 images derived from the original test samples.ContentAff_and_Proj-GTSRB: Main folder.48x48-GTSRB: This folder contains the original GTSRB samples resized to 48x48 pixels.Test: This folder contains the original GTSRB samples resized to 48x48 pixels for testing divided in 43 class folders.Train: This folder contains the original GTSRB samples resized to 48x48 pixels for training divided in 43 class folders.aff-GTSRB: This folder contains the aff-GTSRB datasets group.el30: The aff-GTSRB el=30º dataset for testing.
