| Research Abstract |
We found that the participants could quantitatively estimate the degradation in freshness of the cabbage simply by looking at the presented images. Some parameters of the luminance histograms monotonically change with decreasing freshness, indicating that the freshness of cabbage can be estimated using these parameters. In addition, we investigated the influence of pre-penetration and penetration velocity changes (deceleration/constant velocity/acceleration) on visual hardness judgments. Our findings reveal that visual hardness perception is influenced by velocity changes during penetration. In addition, the current results imply that pre-penetration velocity change, which is not directly related to actual penetration in a natural environment, is one determining factor in visual texture perception.
