Voice activity detection based on facial movement
TL;DR: A new Visual Voice Activity Detection method based on Spatiotemporal Gabor filters (STem-VVAD), which outperforms two reference systems, relying on frame differencing and static Gabor filter filters respectively, showing that Spatiotsemporal gabor filters indeed are beneficial for visual voice detection.

Coastline extraction in remotely sensed images by means of texture features analysis
TL;DR: An improved version of the method has been implemented, which involves texture features, instead of the simple gray level, in order to compute the connectivity map, and is possible to better take into account the spatial variability of data as an information source.

A theory for multiresolution signal decomposition: the wavelet representation
TL;DR: In this paper, it is shown that the difference of information between the approximation of a signal at the resolutions 2/sup j+1/ and 2 /sup j/ (where j is an integer) can be extracted by decomposing this signal on a wavelet orthonormal basis of L/sup 2/(R/sup n/), the vector space of measurable, square-integrable n-dimensional functions.

Statistical and structural approaches to texture
TL;DR: This survey reviews the image processing literature on the various approaches and models investigators have used for texture, including statistical approaches of autocorrelation function, optical transforms, digital transforms, textural edgeness, structural element, gray tone cooccurrence, run lengths, and autoregressive models.

Uncertainty relation for resolution in space, spatial frequency, and orientation optimized by two-dimensional visual cortical filters.
TL;DR: Evidence is presented that the 2D receptive-field profiles of simple cells in mammalian visual cortex are well described by members of this optimal 2D filter family, and thus such visual neurons could be said to optimize the general uncertainty relations for joint 2D-spatial-2D-spectral information resolution.
