Figure 4 shows six test images, Art, Books, Doily, Moebius, RGBD_1, and RGBD_2 used for evaluating the performance of depth enhancement and depth refinement.
Instead of using a water bath around the probe, the new technique improves the visualization of the rectal cancer and contrast enhanced endorectal ultrasound is less affected by attenuation of the enhancement with depth compared with transabdominal sonography [ 17].
The first group of depth image quality enhancement methods aims at correction of systematic errors of TOF sensors and correcting distortions due to non-ideal optical system, as in [4 7].
For details of depth of field enhancement, see supplementary material Methods and Fig. S8.
The light enhancement of various width-to-depth ratios was also simulated in Fig. 10.
Two intervals between the internal and surface region, 300 µm and 500 µm, are used to evaluate the enhancement of image contrast at different depths.
In such situation, the extent of the polluted area was determined using values of soil magnetic susceptibility measured with a MS2D device that were integrated with the values of a width of magnetic enhancement and the depth where it started to be observed in a soil profile.
This study investigated the enhancement of SNAD by varying unsaturated layer depth, vegetation, and pH adjustment with furnace slag in recirculating vertical flow wetlands.
Thus, depth map upsampling [11, 12] followed by its enhancement [13] becomes an inevitable task because the quality of the DIBR process heavily depends on the accuracy of depth information.
The implanted ions were evident to the depths of a few microns, which is much greater than their implantation depths, resulting in an enhancement of surface microhardness.
