AERIAL OBJECT RECOGNITION ALGORITHM BASED ON CONTOUR DESCRIPTOR
vision system object recognition Euler angles geosphere contour descriptor
2017/6/19
This paper describes the image recognition algorithm for on-board and stationary vision system. Suggested algorithm is intended to recognize the aerial object of a specific kind using the set of the r...
FEATURE DESCRIPTOR BY CONVOLUTION AND POOLING AUTOENCODERS
Image Matching Representation Learning Autoencoder Pooling Learning Descriptor Descriptor Evaluation
2015/4/1
In this paper we present several descriptors for feature-based matching based on autoencoders, and we evaluate the performance of these descriptors. In a training phase, we learn autoencoders from ima...
INVESTIGATION OF THE MPEG-7 HOMOGENEUOS TEXTURE DESCRIPTOR FOR THE AUTOMATIC EXTRACTION OF TREES
Urban Vegetation Automation
2015/3/24
In this paper we describe our recent work on the automatic extraction of trees from high resolution aerial images. In order to be more
independent of color information we have investigated textural ...
Sparsely Encoded Local Descriptor for Face Recognition
Random-projection tree Sparse coding face verification face identification
2013/7/24
In this paper, a novel Sparsely Encoded Local Descriptor (SELD) is proposed for face recognition. Compared with K-means or Random-projection tree based previous methods, sparsity constraint is introdu...
A Rotation Invariant Descriptor for Robust Video Copy Detection
CBCD frame-level descriptor rotation invariant HOG
2013/7/24
A large amount of videos on the Internet are generated from authorized sources by various kinds of transformations. Many works are proposed for robustdescription of video, which lead to satisfying ma...
Robust stability for descriptor systems with time-varying delay
Delay systems discrete-time systems uncertain systems
2010/9/21
In this paper, we consider the stability and robust stability for descriptor systems with time-varying delay. First, we attempt to obtain delay-dependent stability conditions via linear matrix inequal...
Sigma Set: A Small Second Order Statistical Region Descriptor
Sigma Set Statistical Region Descriptor
2010/12/20
Given an image region of pixels, second order statistics can be used to construct a descriptor for object representation. One example is the covariance matrix descriptor, which shows high discriminati...
A structure-activity relationship study on the mechanisms of methacrylate-induced toxicity using NMR chemical shift of β-carbon, RP-HPLC log P and semiempirical molecular descriptor
Methacrylates Structure-activity relationships (SAR) Physicochemical properties
2009/9/11
To clarify the mechanism of methacrylate-induced toxicity, a total of 24 acrylates, methacrylates, and dimethacrylates were chosen for a structure-activity relationship (SAR) study in terms of NMR che...
Discrete-Time Sliding-Mode Control of Uncertain Systems with Time-Varying Delays via Descriptor Approach
Discrete-Time Sliding-Mode Control Uncertain Systems Time-Varying Delays Descriptor Approach
2009/9/7
This paper considers the problem of robust discrete-time sliding-mode control (DT-SMC) design for a class of uncertain linear systems with time-varying delays. By applying a descriptor model transform...
Shape Recognition and Classification Based on Poisson Equation- Fourier-Mellin Moment Descriptor
Poisson equation Fourier-Mellin moment shape recognition shape classification
2009/8/19
In this paper, we present a new shape descriptor, which is named Poisson equation-Fourier-Mellin moment Descriptor. We solve the Poisson equation in the shape area, and use the solution to get feature...
Complex Correlation Measure: a novel descriptor for Poincaré plot
Complex Correlation Measure Poincaré plot
2010/2/25
CCM is defined based on the autocorrelation at different lags of the time series, hence giving an in depth measurement of the correlation structure of the Poincaré plot. A surrogate analysis was perfo...
