Dmg 3.5 code#

ClientSocket: This executable is the client-side of the solver, and is responsible for managing the solution of a subset of the image.

It is also responsible for solving the linear system once multigrid has reduced the problem size to a size that can be solved on a single core. Clients connect to it, it establishes all necessary connections and orchestrates the solver.

ServerSocket: This executable acts as the hub of the solver.

Our system is implemented using a client-server model, and our distribution consists of two executables: Formally, if F 1 is the low-frequency image, F 2 is the high-frequency image, α is the fidelity term, and β is the gradient modulation term, the output image G is the image minimizing the sum of square norms:

Smoothing/Sharpening/High-Low Compositing: Given input low- and high-frequency images, a gradient modulation term, and a pixel fidelity term, our code outputs the best-fit image whose gradients match the modulated gradients of the high-frequency input image and whose pixel values match the pixel values of the input low-frequency image.

Stitching: Given an input image consisting of composited images, and given a mask which assigns the same color ID to pixels coming from the same source image, our code outputs the stitched image whose gradients are a best-fit to the gradients of the composite image, with forced zero gradients across seam boundaries.This distribution provides an implementation of our distributed multigrid Poisson solver for image stitching, smoothing, and sharpenting: Version 3.11 Page Version 3.1 Page Version 3 Page Version 2 Page Version 1 Page) DMG Distributed Gradient-Domain Processing of Planar and Spherical Images (Version 3.5) links description executable usage changes
