THIN CLOUD DETECTION METHOD BY LINEAR COMBINATION MODEL OF CLOUD IMAGE
Cloud Detection Image Features Grayscale Texture Linear Model AdaBoost Classifier
2018/5/15
The existing cloud detection methods in photogrammetry often extract the image features from remote sensing images directly, and then use them to classify images into cloud or other things. But when t...
An interior point method for large-scale l1-regularized least squares
Sparse signal the compressed sensing signal processing statistics least squares procedure
2015/8/10
Recently, a lot of attention has been paid to l1 regularization based methods for sparse signal reconstruction (e.g., basis pursuit denoising and compressed sensing) and feature selection (e.g., the L...
A Simple Method of Signal Quality Monitoring for WAAS LNAV/VNAV
Signal Quality Monitoring WAAS LNAV/VNAV
2015/6/26
The integrity of the Wide Area Augmentation System (WAAS), being developed for the FAA, is of significant concern because of its intended use in commercial aviation navigation applications.
Linear Time-of-Arrival Estimation in a Multipath Environment by Inverse Correlation Method
Linear Time-of-Arrival Estimation Multipath Environment Inverse Correlation Method
2015/6/26
The Maximum Likelihood Estimator (MLE) is most often used to estimate the signal time delay in a multipath en vironment. There are various implementations of the MLE which can be divided into the time...
NESTA: A FAST AND ACCURATE FIRST-ORDER METHOD FOR SPARSE RECOVERY
Nesterov’s method smooth approximations of nonsmooth functions `1 minimization duality in convex optimization continuation methods compressed sensing total-variation minimization
2015/6/17
Accurate signal recovery or image reconstruction from indirect and possibly undersampled data is a topic of considerable interest; for example, the literature in the recent field of compressed sensing...
A method of human skin region detection based on PCNN is proposed in this paper. Firstly, the input origin image is translated from RGB color space to YIQ color space, and I channel image is obtained....
An Efficient Coding Method for Intra Prediction Mode Information
Efficient Coding Method Intra Prediction Mode Information
2010/12/20
In H.264/AVC, the bits used for the Intra_4x4 prediction mode information usually occupy a high percentage in intra coding.Towards this issue, we present an efficient coding method for the Intra_4x4 p...
