GradientShop
This is a course project on Computer Graphics.
Implementation of paper GradientShop: A Gradient-Domain Optimization Framework for Image and Video Filtering
The paper has provided GradientShop C++ Framework API, thus I haven't compile it through on neither OS X nor windows. So this is my own implementation, which is based on OpenCV C++ API. Core concept in this project:
- basics: gradient magnitude/orientation
- steerable filter
- local edge length estimation
- saliency
- conjugate gradient (solve quadratic problem)
Applications implemented:
- Saliency Shappening
