Spatial layout and size of the filters learned on whitened natural image patches.

Abstract

<p>(a) for a GRBM-196-196 and (b) for a GRBM-196-588. The layout and size of the filters represented by the position and size of the bars. Each bar denotes the center position and the orientation of a Gabor function fitted to one of the learned filters. Thickness and length of each bar are proportional to the spatial-frequency bandwidth of the corresponding filters.</p
