WebThis minimum resolvable acuity represents one of the fundamental limits of spatial vision: it is the finest high-contrast detail that can be resolved. ln foveal vision the limit is determined primarily by the spacingof photoreceptors in the retina.

Webrepresented. Such an area of somatosensory cortex, about l- 1.5 mm in diameter, may be akin to the “hypercolumn” proposed for primary visual cortex (6). INTRODUCTION The … Webinitial coarse prediction. Their more recent hypercolumn representation makes use of an additional description of each pixel in the network [11]. A similar approach was applied to segmentation in a robotics context by Liu et al. [15]. All these approaches are based on CNN features, but due to the preprocessing, the task of semantic segmentation ...
