Masking Schemes for Image Manifolds
"... I We consider the problem of selecting an optimal mask for images modeled by a manifold, i.e., choosing a subset of the dimensions of the image space that preserves the manifold structure present in the original data. I Such masking implements a form of compressed sensing that reduces power consumpt ..."

Video-based face recognition using probabilistic appearance manifolds
- In Proc. IEEE Conference on Computer Vision and Pattern Recognition
, 2003
"... This paper presents a novel method to model and recognize human faces in video sequences. Each registered person is represented by a low-dimensional appearance manifold in the ambient image space. The complex nonlinear appearance manifold expressed as a collection of subsets (named pose manifolds), ..."

Finding Naked People
, 1996
"... . This paper demonstrates a content-based retrieval strategy that can tell whether there are naked people present in an image. No manual intervention is required. The approach combines color and texture properties to obtain an effective mask for skin regions. The skin mask is shown to be effective f ..."

Fingerprint classification by directional image partitioning
- IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 1999
"... In this work, we introduce a new approach to automatic fingerprint classification. The directional image is partitioned into “homogeneous ” connected regions according to the fingerprint topology, thus giving a synthetic representation which can be exploited as a basis for the classification. A set ..."

of dynamic masks, together with an optimization criterion, are used to guide the partitioning. The adaptation of the masks produces a numerical vector representing each fingerprint as a multidimensional point, which can be conceived as a continuous classification. Different search strategies are discussed

Point-Wise Extended Visual Masking For JPEG-2000 Image Compression
"... One common visual optimization strategy for image compression is to exploit the visual masking effect where artifacts are locally masked by the image acting as a background signal. In this paper, we present a point-wise extended visual masking approach that nonlinearly maps the wavelet coefficients ..."

The Noh mask effect: vertical viewpoint dependence of facial expression perception
- B
, 2000
"... Full-face masks, worn by skilled actors in the Noh tradition, can induce a variety of perceived expressions with changes in head motion. Out-of-plane rotation..., and we discuss how perceptual strategies for ascribing expression to familiar and unfamiliar images may account for the differences. ..."

Phase Errors in Diffraction-Limited Imaging: Contrast Limits for Sparse Aperture Masking
, 2013
"... Bispectrum phase, closure phase and their generalisation to kernel-phase are all in-dependent of pupil-plane phase errors to first-order. This property, when used with Sparse Aperture Masking (SAM) behind adaptive optics, has been used recently in high-contrast observations at or inside the formal d ..."
