Brodatz Texture Rotation Dataset
Department of Electrical and Computer Engineering, University

Description
This database contains 32 texture images digitized from a set of black and white
prints of the Brodatz’s Album¹. Figure 1 shows samples from each
class selected from 110 classes available in Brodatz’s Album. The original images acquired were rotated by
hardware in 21 rotation angles
θ = {0°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, 90°, 100°, 110°,
120°, 130°, 135°, 140°, 150°, 160°, 170°, 180°}. In addition,
the images with a 0° orientation angle were software-rotated by mean
of five computational
interpolation methods: Cubic B-spline, Nearest Neighbor, Linear, Third Order Cubic,
and Lanczos using the DIPimage
toolbox².

Image acquisition
setup
The acquisition
system (Figure 2) is composed
by a ruler with 360º rotating axis and a digital câmera Sony DSC-W350 (14.1 megapixels,
sensor super HAD CCD 1/2.3 7.76 mm and Carl Zeiss Vario-Tessar lens). The images acquired in 21 orientations have 640 x 480 pixels and were converted to grayscale
and saved as JPEG files. After
the software-rotation, the images were
saved as PNG files.

The dataset is available
as .zip files:
The image files are named as follows: BS_C001_010.png, where BS is the rotation method,
C001 is the texture class
name and 010 is the rotation
angle 10°.
