- The dataset contains line drawings of 260 general object, which are a standard set of objects that have been frequencly used in the psychophysics community for tests with human subjects.
- Only line drawings available, without any texture and color information
- Has only one image per object,
Only shape matters, color and other surface characteristics are not part of an object representation (e.g. Biederman, 1987)
However, Object naming is facilitated by congruent surface color and photographic detail as compared to line drawings (Price & Humphreys, 1989)
Texture and color contribute to object recognition for all categories of objects, including artefacts without any dagnostic color.
- Better segmentation ? (perceptual contribution)
- Better recognition ? (“knowledge-based” contribution)
When all informations are available, objects are recognized at the same speed, suggesting that recognition of an object is based on multiple cues, with contour and surface information all part of an object representation and providing important information for recognition.
