Other Implementations

Core of GradientShop
"GradientShop: A Perceptually-Motivated Optimization-Framework for Image and Video Processing"
The implementation does not include the interface for the applications introduced in the paper, but does include the core (section 3) of the mechanism.
Core of Interactive Local Adjustment of Tonal Value
"Interactive Local Adjustment of Tonal Value"
The implementation does not include the interface for tone mapping application, but does include the core (section 3.2 and section 3.3 of the paper) of the mechanism.
Poisson Solver
"Poisson Image Editing"
"GrabCut X Interactive Foreground Extraction using Iterated Graph Cuts"
"Region Filling and Object Removal by Exemplar-Based Image Inpainting" and
"Gradient based image completion by solving the Poisson equation"
Closed-form matting & Robust matting
Warning!!! BUG exists (in robust matting). Maybe I'll revise it and update in the future.

"A Closed Form Solution to Natural Image Matting" and
"Optimized Color Sampling for Robust Matting"
2D Stick Tensor Voting
"A Computational Framework for Segmentation and Grouping" and
Chapter 5 of "Emerging Topics in Computer Vision"
