In details, edge ei,j is associated with message mi,j (and mj,i if the message passing is bi-directional).
Detailed edge or object recognition is not necessary.
Normalized images were spatially denoised using a wavelet-based three-dimensional denoising approach, which not only suppresses noise but also preserves essential spatial details (edge and shape of activation) that are often suppressed in Gaussian smoothing (40).
Our objectives were: (1) to compare the length of natural and created edges, (2) to classify edges in detail by edge origin, maintenance and forest attributes, and (3) to examine relationships between length of edge and landscape variables.
From Figure 12, one can see that the proposed framework achieves the best results in details, edges, and preservation of chromaticity.
This may come from the known fact that alongside the positive effect of noise suppression any filter more or less distorts useful information, such as details, edges, texture.
The simulation results under the proposed criteria PSNR, MAE, and NCD were used to characterize an algorithm's efficiency in noise suppression, fine details, edges, and chromatic properties preservation.
In case there is a drastic change in the fine details, edges, and movements in the current samples, these will be reflected in their parameter values - such as the membership functions, the SD, and the sensitivity parameters, as well as in their fuzzy vectorial-gradient values.
This example clearly illustrates that the scale-based classification map readily indicate locations of highly homogeneous, detail and edge regions.
Figure 7 shows the frames of the original video sequences subjectively used to characterize the noise suppression, detail and edge preservation, and the chromaticity.
