Local feature selection for efficient binary descriptor coding

2014 IEEE International Conference on Image Processing (ICIP), 2014
In a visual sensor network, a large number of camera nodes are able to acquire and process image data locally, collaborate with other camera nodes and provide a description about the captured events. Typically, camera nodes have severe constraints in terms of energy, bandwidth resources and processing capabilities.

Learning Local Feature Descriptors with Quadruplet Ranking Loss

2017
In this work, we propose a novel deep convolutional neural network (CNN) with quadruplet ranking loss to learn local feature descriptors. The proposed model receives quadruplets of two corresponding patches and two non-corresponding patches, and then outputs features measured by \(L_2\) norm with dimension (256d) close to that of SIFT, which thus can ...

Local feature descriptor invariant to monotonic illumination changes

Journal of Electronic Imaging, 2016
This paper presents a monotonic invariant intensity descriptor (MIID) via spectral embedding and nonsubsampled contourlet transform (NSCT). To make the proposed descriptor discriminative, NSCT is used for the construction of multiple support regions. Specifically, the directed graph and the spectral feature vectors of the signless Laplacian matrix are ...

Bag of Features vs Vector of Locally Aggregated Descriptors

2017
Image representation by set of local features are common and also state-of-the art for many applications such as image retrieval and image classification. A single image contains on average 2.5 k–3.0 k features. Searching the images based on local features are discriminative compared to global features at the cost of heavy computational overhead.
