Kylberg Texture

A number of textured surfaces, including fabrics and surfaces of stone, were imaged in the local surroundings. Textured surfaces were also arranged using articles such as rice grains, sesame seeds and lentils. Each texture class was imaged under only one light setting from one direction on the same distance. The images were acquired with a Canon EOS 550d DSLR camera with a Sigma 17-70 mm zoom lens. Focus and exposure were manually set. The 5*,* 184 ¡Á 3*,* 456 pixel size images were acquired as lossless compressed raw fifiles (CR2). The raw fifiles were corrected for lens distortion, chromatic aberration and vignetting formed by the Sigma lens. The corrections was performed according to the settings in the ¡°Adobe (SIGMA 17-70mm F2.8-4 DC Macro OS HSM, Canon)¡± lens profifile in Adobe Photoshop CS5 .The images were then converted to gray scale and saved as lossless PNG fifiles. Lens correction and raw conversion was done in Adobe Photoshop CS5.

本数据集对多种纹理表面开展成像采集，涵盖织物与石材表面，采集工作在本地环境中完成。此外，还利用米粒、芝麻籽与扁豆等食材搭建了纹理表面样本。每一类纹理样本仅在单一光照设置下、从单一方位且保持相同拍摄距离完成成像。图像采集使用佳能EOS 550D数码单反相机（Canon EOS 550d DSLR）搭配适马17-70mm变焦镜头（Sigma 17-70 mm zoom lens）完成，对焦与曝光参数均采用手动设置。采集的图像分辨率为5184×3456像素，以无损压缩原始文件（CR2）格式存储。针对适马镜头产生的镜头畸变、色差与暗角，对原始CR2文件进行校正处理，校正流程遵循奥多比（Adobe）Photoshop CS5内置的「适马17-70mm F2.8-4 DC Macro OS HSM（佳能卡口）」镜头配置文件参数执行。随后将图像转换为灰度图，并以无损PNG格式存储。镜头畸变校正与原始文件格式转换均在奥多比（Adobe）Photoshop CS5中完成。
