FEATURE DESCRIPTOR BY CONVOLUTION AND POOLING AUTOENCODERS [PDF]

open access: diamondThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
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 image patches extracted in local windows surrounding key ...

Learning Spread-out Local Feature Descriptors [PDF]

open access: yes2017 IEEE International Conference on Computer Vision (ICCV), 2017
We propose a simple, yet powerful regularization technique that can be used to significantly improve both the pairwise and triplet losses in learning local feature descriptors.

A short feature vector for image matching: The Log-Polar Magnitude feature descriptor. [PDF]

open access: yesPLoS ONE, 2017
The choice of an optimal feature detector-descriptor combination for image matching often depends on the application and the image type. In this paper, we propose the Log-Polar Magnitude feature descriptor-a rotation, scale, and illumination invariant ...

Feature-Combined Binary Descriptor Algorithm Based on Ring Sampling [PDF]

open access: greenJisuanji gongcheng, 2019
To improve the discrimination ability and robustness of binary descriptors,we propose a new feature-combined binary descriptor algorithm.First,we divide the circular neighborhood of the sampling point into multiple ring domains,and compare the grayscale ...

Enhanced Feature Descriptor Based on Attention Mechanism [PDF]

open access: yesJisuanji gongcheng, 2021
When the traditional manual method is used to obtain the feature descriptors,it can not guarantee the correct matching of the feature points in the nonlinear deformation state,and can not solve the problem of feature description when the image has large ...
