Relational autoencoder for feature extraction [PDF]

open access: yes2017 International Joint Conference on Neural Networks (IJCNN), 2017
Feature extraction becomes increasingly important as data grows high dimensional. Autoencoder as a neural network based feature extraction method achieves great success in generating abstract features of high dimensional data. However, it fails to consider the relationships of data samples which may affect experimental results of using original and new

Indoor image representation by high-level semantic features [PDF]

open access: yesIEEE Access 7 ,2019, 2019
Indoor image features extraction is a fundamental problem in multiple fields such as image processing, pattern recognition, robotics and so on. Nevertheless, most of the existing feature extraction methods, which extract features based on pixels, color, shape/object parts or objects on images, suffer from limited capabilities in describing semantic ...

Coloring Local Feature Extraction [PDF]

open access: yes, 2006
Although color is commonly experienced as an indispensable quality in describing the world around us, state-of-the art local feature-based representations are mostly based on shape description, and ignore color information. The description of color is hampered by the large amount of variations which causes the measured color values to vary ...
