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...
Analysis of Noise and Cycle Selection in a Loran Receiver
Analysis of Noise Cycle Selection Loran Receiver
2015/6/25
Thermal and atmospheric noise distort envelope measurements in a Loran receiver, and may cause the receiver to select the wrong cycle during signal acquisition. A cycle error would persist during sign...
SELECTION OF A SCIENTIFIC DATA MANAGEMENT SYSTEM (SDMS) BASED ON USER REQUIREMENTS
Pharmaceutical research quality control
2015/5/26
Pharmaceutical research/development and quality control laboratories are faced with prodigious amounts of data from a multitude of heterogeneous data sources in a compliant manner, as mandated by requ...
DIMENSIONALITY BASED SCALE SELECTION IN 3D LIDAR POINT CLOUDS
point cloud adaptive neighborhood scale selection multi-scale analysis feature PCA eigenvalues dimensionality
2014/6/5
This papers presents a multi-scale method that computes robust geometric features on lidar point clouds in order to retrieve the optimal neighborhood size for each point. Three dimensionality features...
Visual Selection and Attention Shifting Based On FitzHugh-Nagumo Equations
F-N model Neural Network Visual Selection
2010/12/21
In this paper, we make some analysis on the FitzHugh-Nagumo model and improve it to build a neural network, and the network is used to implement visual selection and attention shifting. Each group of ...
Dual Frame Motion Compensation with Optimal Long-Term Reference Frame Selection and Bit Allocation
Dual Frame Motion Compensation Optimal Long-Term Reference Frame Selection Bit Allocation
2010/12/21
In dual frame motion compensation (DFMC), one short-term reference frame and one long-term reference frame (LTR) are utilized for motion compensation. The performance of DFMC is heavily influenced by ...
Rate Distortion Modeling of Skip Mode and Early Skip Mode Selection for H.264/MPEG-4 AVC
Rate Distortion Modeling Skip Mode Early Skip Mode
2010/12/20
This paper proposed a linear rate-distortion (RD) cost model for skip mode in H.264. The proposed RD cost model is derived theoretically based on the quantization scheme of H.264, and the simulation r...
Design Two-Dimensional IIR Filters Based on Clonal Selection Algorithm with Singular Value Decomposition
Design Two-Dimensional IIR Filters Clonal Selection Algorithm Singular Value Decomposition
2009/9/4
In this letter, clonal selection algorithm (CSA) with singular value decomposition (SVD) method is investigated for the realization of two-dimentional (2D) infinite-impulse response (IIR) filters with...
AIRBORNE LIDAR FEATURE SELECTION FOR URBAN CLASSIFICATION USING RANDOM FORESTS
Lidar Full-waveform Classifi cation Feature selection Random Forests Urban scenes
2016/2/29
Various multi-echo and Full-waveform (FW) lidar features can be processed. In this paper, multiple classifers are applied to lidar
feature selection for urban scene classification. Random fores...
DRM: Dynamic Region Matching for Image Retrieval Using Probabilistic Fuzzy Matching and Boosting Feature Selection
Dynamic Region Matching Image Retrieval Probabilistic Fuzzy Matching
2010/12/17
This paper considers the semantic gap in content-based image retrieval from two aspects: (1)
irrelevant visual contents (e.g. background) scatter the mapping from image to human perception; (2) unsup...
Macroblock-level Reduced Resolution Video Coding Allowing Adaptive DCT Coefficients Selection
Video Coding DCT Coefficients Selection
2010/12/17
Reduced Resolution Update (RRU) video coding provides a better compression performance than H.264/AVC does. It is implemented by encoding the predicted residuals after downsampling
at the encoder and...
MEAN-SHIFT BLOB TRACKING WITH ADAPTIVE FEATURE SELECTION AND SCALE ADAPTATION
MEAN-SHIFT BLOB TRACKING FEATURE SELECTION SCALE ADAPTATION
2010/12/17
When the appearances of the tracked object and surrounding background change during tracking, fixed feature space tends to cause tracking failure. To address this problem, we propose a method to embed...
