Feature Extraction,pattern recognition,entropy,Pulse-Coupled Neural Network (PCNN)The entropy sequence of the output image, gotten from the original gray image by Pulse-Coupled Neural Network (PCNN), as feature vector of the gray image, can be used as a unique feature expression of gray image,...
One typical use of feature extraction is finding features in images. Using these features can lead to improved classification accuracy. For an example, seeFeature Extraction Workflow. Another typical use is extracting individual signals from superpositions, which is often termed blind source separation....
We introduce a new architecture for feature extraction from multitemporal synthetic aperture radar (SAR) data. Its the purpose is to combine classic SAR processing and geographical object-based image analysis to provide a robust unsupervised tool for information extraction from time series images. The...

In multi-dimensional image, ICA-based feature extraction algorithm, which is proposed in this paper, is for the purpose of detecting target feature about pixel assumed as a linear mixed spectrum sphere, which is consisted of each different type of material object (target feature and background fe...
This image feature extraction device extracts, from an image, an image feature that makes it possible to adjust the balance between identification capability and robustness, which are the scales of the capability of determining identity of images. This image feature extraction device executes ...
