A Simple Framework for Face Photo-Sketch Synthesis

Figure 5

The input intensities (red) along a row and its decomposition into base (green) and detail by bilateral filtering. Row 1 is the input image and its scanline plots of intensity. Row 2 and row 3 are the base image and detail image using different scales of intensity and spatial domain. Row 2 shows that weak edges and reflecting details are preserved in detail image at large spatial scale and small intensity scale. Row 3 shows that the sharp edge of facial features is preserved in detail image at small spatial scale and large intensity scale.
