Boundary Detection Using Double-Opponency and Spatial Sparseness Constraint

Abstract: Brightness and color are two basic visual features integrated by the human visual system (HVS) to gain a better understanding of color natural scenes. Aiming to combine these two cues to maximize the reliability of boundary detection in natural scenes, we propose a new framework based on the color-opponent mechanisms of a certain type of color-sensitive double-opponent (DO) cells in the primary visual cortex (V1) of HVS. This type of DO cells has oriented receptive field with both chromatically and spatially o… Show more

“…The mean computation time to compute one contour map with gPb [ 1 ] is 191 s, while our algorithms only takes 13 s (the computer used here is Intel Core 2, 2.5 GHZ with 8.0 G RAM). Our method is a littler slower than CO [ 48 ] and SCO [ 75 ]. Note that, CO [ 48 ] and SCO [ 75 ] only perform at a single scale, because their extension into multi-scale space did not yet produce clear performance improvements [ 48 , 75 ].…”

In addition, in order to explore the impact of different kinds of edge strength on the segmentation accuracy, we also tested the SH methods that incorporate edge strength obtained by the structured forest edge (SH+SFE) method [28], the sparseness-constrained color-opponency (SH+SCO) method [26], the automated anisotropic Gaussian kernel (SH+AAGK) method [19], and the surrounded-modulation edge detection (SH+SED) method [27]. Furthermore, we also selected the widely used SLIC method [8] for comparison.…”
