Sentence examples for descriptor of the image from inspiring English sources
The resulting aggregated representation is then compressed by PCA to obtain the final compact descriptor of the image.
Ojala et al. [20] used LBP as a texture descriptor of the image as shown in Figure 2, which is composed by central pixel and neighborhoods.
The present system is mainly developed based on the visual descriptors of the image such as color, texture and shape descriptors, etc. along with the high-level semantic analysis of the image content through different processing modules in the proposed architecture.
With our previous approach, however, HD4AR matched feature descriptors of the image to an entire set of feature descriptors from all base images, which incurs unnecessary descriptor comparisons.
HD4AR only compares feature descriptors of the image to that of each 3D point in the point cloud to find 2D-to-3D correspondences.
With the improvements presented in this paper, HD4AR now directly compares feature descriptors of the image to that of 3D points in a point cloud, which reduces matching time significantly.

Recent work deals with combination of distances or scores from different and usually independent representations in an attempt to induce high level semantics from the low level descriptors of the images.
In practice, we refine the injected image as follows: first, we individuate the new keypoints presenting a correct match with their homologue (wrong matches are instead welcome); second, we discard them by inserted back into Iinj a corresponding patch (16×16 pixels which is the computational window of the SIFT descriptor) of the cleaned image Irem.
