Edge-Preserving Integration of a Normal Field: Weighted Least-Squares, TV and L^1 Approaches
Abstract. We introduce several new functionals, inspired from variational image denoising models, for recovering a piecewise-smooth surface from a dense estimation of its normal ...

Variational Perspective Shape from Shading
Many recent methods for perspective shape from shading (SfS) are based on formulations in terms of partial differential equations (PDEs). However, while the quality of such methods...

Content-Fragile Commutative Watermarking-Encryption Based on Pixel Entropy
Content-fragile commutative watermarking-encryption requires that both the content-fragile image signature and the watermarking process are invariant under encryption. The pixel en...

Fast and Robust Variational Optical Flow for High-Resolution Images Using SLIC Superpixels
We show how pixel-based methods can be applied to a sparse image representation resulting from a superpixel segmentation. On this sparse image representation we only estimate a sin...
