SAMPLING

Mon, 01 Jan 0001 00:00:00 +0000

Download TESTIMAGES/SAMPLING archive

The main purpose of this dataset is providing natural images to test resampling algorithms (i.e. interpolation, zooming, enlargment and superresolution).
This dataset uniquely provides a base of 40 RBG 2400x2400 reference images with a bit-depth of 16bpp and high dynamic range (HDR).
The reference images were processed to obtain different sub-resolutions and variation with 8bpp and grayscale, for a total of more 220K images.

SAMPLING_PATTERNS

Download TESTIMAGES/SAMPLING_PATTERNS archive

This is an extension of the SAMPLING archive containing 424 artificial Grayscale reference images, generated as described in the PATTERNS section for the 1224x1224 pixels resolution.
The main purpose of this dataset is to test in isolation specific features of resampling algorithms.

PATTERNS

Download TESTIMAGES/PATTERNS archive

The main purpose of this dataset is providing images to test the rendering of standard geometrical patterns by displays, monitors, televisions and projectors.
These patterns facilitate the adjustment of geometrical parameters and helps identify defects of the rendering device.
The broad range of simple geometrical patterns also helps to optimize or identify specific issues in some image processing algorithms. For example, by verifying if the patterns are preserved when applying an image compression algorithm, by testing the effects of different texture filtering and resampling approaches programmed in shaders, or by evaluating the printing quality of a particular device.

Download TESTIMAGES/COLOR archive

The main purpose of this dataset is providing images to test the color rendering on different displays and facilitate color adjustments.

This and the PATTERNS archive contain 8bpp and 16 bpp (bit-per-pixel) 3-Channel Red-Green-Blue (RGB) images for the following 114 standard and non-standard resolutions for computer monitors, televisions, cinema projectors, mobile phone screens, camera sensors and other generic displays:
