New shape descriptor in the context of edge continuity
CAAI Transactions on Intelligence Technology, 2019 The object contour is a significant cue for identifying and categorising objects. The current work is motivated by indicative researches that attribute object contours to edge information.

Spherical harmonics coefficients for ligand-based virtual screening of cyclooxygenase inhibitors. [PDF]
PLoS ONE, 2011 Molecular descriptors are essential for many applications in computational chemistry, such as ligand-based similarity searching. Spherical harmonics have previously been suggested as comprehensive descriptors of molecular structure and properties.

Nested Shape Descriptors [PDF]
2013 IEEE International Conference on Computer Vision, 2013 In this paper, we propose a new family of binary local feature descriptors called nested shape descriptors. These descriptors are constructed by pooling oriented gradients over a large geometric structure called the Hawaiian earring, which is constructed with a nested correlation structure that enables a new robust local distance function called the ...

Chordiogram image descriptor based on visual attention model for image retrieval
Array, 2020 A novel shape-based image retrieval is presented in this study. The foreground and background contents of images are strongly concealed, so they are represented individually to reduce their influence on each other in the proposed approach.

Enlacement and Interlacement Shape Descriptors [PDF]
, 2020 We propose a novel approach to characterize complex 2D shapes based on enlacement and interlacement directional spatial relations. This new relational concept allows to assess in a polar space how the concave parts of objects are intertwined following a set of directions.
