To date, the numerous approaches [3-8] have been proposed for image inpainting since the seminal work of BSCB [3,4]: for example, the classical Total Variation (TV) [7] and Curvature-Driven Diffusion (CDD) [8] models, which are based on solving Partial Differential Equation (PDE) to preserve the directions of the isophotes in the missing region.
By using third-order PDE model, the algorithm allows for the curvature of isophote lines.
In the steady state, when [partial derivative]u/[partial derivative]t = 0, the direction of the largest information change is perpendicular to the isophotes.
Finally, isophotes (lines of equal brightness) were created to show the terminator's curvature more clearly.
The isophotes created on my images correspond to an intensity level of about 20 percent of the brightest area on venus.
The isophotes, or contours of equal brightness, are approximately circular around the center and the variation of brightness outward is close to that of an inverse square law.
The software will stack and average images, center them with respect to each other, mosaic them to create wide-field scenes, display a histogram of pixel intensities, display isophotes, blink two images to compare differences, and perform photometry on starlike objects.
He presented a challenging crop of discordant redshift oddities using false-color, visible-light images overprinted with X-ray isophotes.
