| + | =====Abstract===== | ||
| + | |||
| + | In computer vision and image processing, we often perform different processing on “objects” than on “texture.” In order to | ||
| + | do this, we must have a way of localizing textured regions of an image. For this purpose, we suggest a working definition of | ||
| + | texture: Texture is a substance that is more compactly represented by its statistics than by specifying the configuration of its | ||
| + | parts. Texture, by this definition, is stuff that seems to belong to the local statistics. Outliers, on the other hand, seem to | ||
| + | deviate from the local statistics, and tend to draw our attention, or “pop out”1, 2. This definition suggests that to find texture | ||
| + | we first extract certain basic features and compute their local statistics. Then we compute a measure of saliency, or degree to | ||
| + | which each portion of the image seems to be an outlier to the local feature distribution, and label as texture the regions with | ||
| + | low saliency. We present a method, based upon this idea, for labeling points in natural scenes as belonging to texture | ||
| + | regions. This method is based upon recent psychophysics results on processing of texture and popout. | ||
