A toolbox and sample object perception data for equalization of natural images.

Bainbridge WA, Oliva A - Data Brief (2015)

Bottom Line: For psychologists and neuroscientists, careful selection of their stimuli is essential, so that low-level visual features such as color or spatial frequency do not serve as confounds between conditions of interest.Additionally, we provide a set of object images varying along several perceptual object properties, including physical size and interaction envelope size (i.e., the space around an object transversed during an interaction), serving as a test-bed for the Natural Image Statistical Toolbox.This stimulus set is also a highly characterized set useful to psychology and neuroscience studies on object perception.

ABSTRACT
For psychologists and neuroscientists, careful selection of their stimuli is essential, so that low-level visual features such as color or spatial frequency do not serve as confounds between conditions of interest. Here, we detail the Natural Image Statistical Toolbox, which allows scientists to measure, visualize, and control stimulus sets along a set of low-level visual properties. Additionally, we provide a set of object images varying along several perceptual object properties, including physical size and interaction envelope size (i.e., the space around an object transversed during an interaction), serving as a test-bed for the Natural Image Statistical Toolbox. This stimulus set is also a highly characterized set useful to psychology and neuroscience studies on object perception.

f0010: The 360 object images included in the Object Interaction Envelope Stimuli set. Object properties for all small-scale object images are also included.

Mentions: The stimulus set includes 320 images of isolated objects against a white background, where 160 of the images are large-scale objects of both big physical size and interaction envelope, and 160 are images of small-scale objects (see Fig. 2). Within the small-scale object set, there are four smaller conditions with 40 images each that orthogonalize real-world physical size and object interaction envelope: 1) objects of both small physical size and envelope size, 2) objects of both large physical size and envelope size, 3) objects of small physical size and large envelope size, and 4) objects of large physical size and small envelope size. Images are all JPEG images of 350×350 pixels in size. Using the Natural Image Statistical Toolbox, these images were selected so that the four conditions did not differ in average RGB color, amount of white space, luminance, or spatial frequency information.
