This paper introduces a practical way to improve the risk management capacity and resilience of communities by utilizing a prompt flash flood map produced from very high spatial resolution ALOS-2 data...
Likelihood-based classification of high resolution images to generate the initial topology and geometry of land cover segments
Likelihood-based classification Maximum likelihood classification Geo-information systems
2016/5/20
This paper’s origin is to reach for a way for automatic initiation of shape hypothesis for Model Based Image Analysis (MBIA) in the specific case of agricultural fields. A solution is to start with lo...

Change Detection Large Scale Urban Monitoring Urban Growth PCA NDVI IHS Quickbird
2015/8/31
Very high resolution space borne imagery is essential for a large scale and very detailed urban monitoring and the Quickbird sensor
is one of those. It offers images with a spatial resolution of 0.6...
VERY HIGH SPATIAL RESOLUTION IMAGE SEGMENTATION BASED ON THE MULTIFRACTAL ANALYSIS
Remote Sensing Vision Analysis Algorithms Texture Segmentation High Resolution Multifractal CDROM
2015/7/29
The availability of very high spatial resolution images in remote sensing brings the texture segmentation of images to a higher level
of complexity. Such images have so many details that the classic...
Hopfield Networks in Relevance and Redundancy Feature Selection Applied to Classification of Biomedical High-Resolution Micro-CT Images
feature selection image features pattern classification
2015/7/28
We study filter–based feature selection methods for classification of biomedical images. For feature selection, we use two filters — a relevance filter which measures usefulness of individual features...

Cascade Integer Resolution Civil GPS Frequencies
2015/6/29
In the near future, there will be two more civil GPS signals in addition to the current one at the L1 frequency (1575.42 MHz). The second civil signal will be broadcast at the L2 frequency (1227.60 MH...
Super-Resolution from Noisy Data
Deconvolution stable signal recovery sparsity line spectra estimation basis mismatch superresolution factor
2015/6/17
This paper studies the recovery of a superposition of point sources from noisy bandlimited data. In the fewest possible words, we only have information about the spectrum of an object in the lowfreque...
Towards a Mathematical Theory of Super-Resolution
Diffraction limit deconvolution stable signal recovery sparsity sparse spike trains, `1 minimization dual certificates interpolation super-resolution semidefinite programming
2015/6/17
This paper develops a mathematical theory of super-resolution. Broadly speaking, superresolution is the problem of recovering the fine details of an object—the high end of its spectrum— from coarse sc...
Super-resolution via Transform-invariant Group-sparse Regularization
Super-resolution Transform-invariant Group-sparse
2015/6/17
We present a framework to super-resolve planar regions found in urban scenes and other man-made environments by taking into account their 3D geometry. Such regions have highly structured straight edge...
In single-molecule microscopy it is necessary to locate with high precision point sources from noisy observations of the spectrum of the signal at frequencies capped by fc, which is just about the fre...
