This feature enables us to properly distinguish flat image regions respect to edge and detail regions.
The experimental and CFD results showed the detail regions of local heating that correlated with the NiO nanoparticle size.
In detail, regions at sculptures and characters, respectively, shown in Figures 21 and 22 have successfully been reconstructed by the proposed method.
In the map, black regions are homogeneous, gray regions represent detail regions, while white regions manifest inhomogeneities that indicate most of the important features, e.g., the camera and tripod.
Nevertheless, Gilboa et al. [38] proposed that the same α is used for the entire image, regardless of local structures of an image, which leads to over-smoothing in edge or detail regions and under-smoothing in homogeneous regions.
The color attenuation relationship also improves the shadow detection performance in many detail regions when compared with Tsai's and Chung et al.'s algorithm in Figures 5, 6, 7, 8, 9 and 10.
However, if we inspect the seismic tomography images (Fig. 20) of Nakajima et al. (2009c) in detail, regions with P-wave velocity below 7 km/s are distributed entirely along the lower plane of the double seismic zone.
In homogeneous and detail regions, the traditional 4-connected neighbourhood diffusion discretization equation is performed to update I x, y, t); while in edge regions, the 8-connected neighbourhood diffusion discretization equation (28) is performed to update I x, y, t). .
