Identify the background boundary of the holes using the hole depth threshold Z A S. Compute the priority on the background boundary using the curvature data term and depth-based confidence term and select a patch with the highest priority.
The steps of the inpainting process are as follows: 1. Identify the background boundary of the holes using the hole depth threshold Z A S. 2.
Compute the priority on the background boundary using the curvature data term and depth-based confidence term and select a patch with the highest priority.
The improved Sobel operator was used in the software, which improved greatly the ability of distinguishing between the test area and background boundary information.
The priority term on the background boundary is the product of confidence and data terms: {Pleft(mathbf{p}right)}={C_{z}left(mathbf{p}right)}cdot{D_{k}left(mathbf{p}right)}, (18).
The background boundary of the hole is identified by classifying the hole boundary into the foreground and background using the depth threshold image Z A S. The classification proceeds as follows: Initially, the hole boundary δ Ω is obtained by applying a Laplacian convolution on the hole region.
In this system, the white and ultra-violet (UV) light of optical device was designed, which was tunable with different strips, and the Sobel operator algorithm was used in the software, which could enhance the identification ability to recognize the test area from the background boundary information.
Next, the hole boundary is classified into the foreground boundary δ Ω F and the background boundary δ Ω B, i.e. δ Ω=δ Ω F ∪δ Ω B. Let us begin by defining the maximal value of the occlusion threshold on the 2D patch at point p, Ψ p, coinciding with the source region Φ: mu = maxleft(mathrm{Z}_{{AS}}left(mathbf{q}right)|_{mathbf{q} in (Psi_{mathbf{p}}capOmega)} right) (15).
Finally, when our in silico wing primordium lacks Cut activity (either in clones of mutant cells or in a mutant background), boundary cells start responding to the Wg signal, as shown by the expression of Senseless (Figures 4andand 4B') and ectopic activation of Notch in non-boundary cells is now unable to block the Wg signaling pathway (Figure 4C').
are segments containing local maxima with higher intensity values and are defined as structural boundary segments (Figs 2E and 7D), whereas are defined as background boundary segments.
