RepFinder: Finding Approximately Repeated Scene Elements for Image Editing
A novel framework that uses rough inputs to detect and robustly extract repetitions along with their mutual relations. The paper demonstrates the versatility of the framework on a large set of inputs and demonstrates a number of applications.
Edge-Based Image Coarsening
This new dimensionally reduced linear image space allows a number of recent image-manipulation techniques to be performed efficiently and robustly. Results show that the reduced representation is useful for energy-minimization methods in achieving efficient processing and providing better matrix conditioning with minimal quality sacrifice.
GradientShop: A Gradient-Domain Optimization Framework for Image and Video Filtering
This paper presents an optimization framework for exploring gradient-domain solutions for image and video processing. The utility of the framework is demonstrated by creating several effective yet simple to implement solutions for various image-processing tasks.
Distributed Gradient-Domain Processing of Planar and Spherical Images
This paper extends gradient-domain image processing by adapting the approach to operate on spherical imagery and proposing a distributed solver to efficiently process large images. The authors demonstrate the approach on several datasets, including a terapixel spherical scan of the night sky.
