On Convergent Finite Difference Schemes for Variational - PDE Based Image Processing
V. B. S. Prasath, Juan C. Moreno
We study an adaptive anisotropic Huber functional based image restoration scheme. By using a combination of L2-L1 regularization functions, an adaptive Huber functional based energ…
Robust Periocular Recognition By Fusing Sparse Representations of Color and Geometry Information
Juan C. Moreno, V. B. S. Prasath, Gil Santos +1
In this paper, we propose a re-weighted elastic net (REN) model for biometric recognition. The new model is applied to data separated into geometric and color spatial components. T…
Radar shadow detection in SAR images using DEM and projections
V. B. S. Prasath, O. Haddad
Synthetic aperture radar (SAR) images are widely used in target recognition tasks nowadays. In this letter, we propose an automatic approach for radar shadow detection and extracti…
Brain MRI Segmentation with Fast and Globally Convex Multiphase Active Contours
Juan C. Moreno, V. B. S. Prasath, Hugo Proenca +1
Multiphase active contour based models are useful in identifying multiple regions with different characteristics such as the mean values of regions. This is relevant in brain magne…
Color image denoising by chromatic edges based vector valued diffusion
V. B. Surya Prasath, Juan C. Moreno, K. Palaniappan
In this letter we propose to denoise digital color images via an improved geometric diffusion scheme. By introducing edges detected from all three color channels into the diffusion…
