Scalar Edge Detectors [link]Paper  abstract   bibtex   
DefinitionSince color images are arrays of three-component color vectors, the use of scalar edge detectors requires pixels’ dimensionality reduction through the conversion of the color image to its luminance-based equivalent.Since color images are arrays of three-component color vectors, the use of scalar edge detectors requires pixels’ dimensionality reduction through the conversion of the color image to its luminance-based equivalent [1,2]. Then traditional (scalar) edge operators, such as those used in gray-scale imaging are applied to the luminance image to obtain the corresponding edge map (Fig. 1).Scalar Edge Detectors. Figure 1.Scalar color edge detection based on dimensionality reduction.Alternatively, the edge map of the color image can be achieved using component-wise processing [1–3]. In this way, each of the three color channels are processed separately (Fig. 2). The operator then combines the three distinct edge maps to form the output map. The output edge descri ...
