Recognition of building shape in maps using deep graph filter neural network

open access: yesGeocarto International, 2023
Shape is one of the core features of the buildings which are the main elements of the map. The building shape recognition is widely used in many spatial applications.

A novel shape classification method using 1‐D convolutional neural networks

open access: yesIET Image Processing, 2023
Most of the shape classification methods are based on a single closed contour. However, practical shapes always have complex contours, for example, a combination of multiple open contours. How to accurately identify complex shapes is an unsolved problem.

Breast shape recognition based on extreme learning machine

open access: yesXi'an Gongcheng Daxue xuebao, 2022
In view of the low accuracy of breast shape recognition, the approach of CFSFDP was used to cluster the breast shape of 108 young female breast forms in west region, and then the ELM algorithm was used to identify breast shape.

Algorithm for image-based architectural element recognition [PDF]

open access: yesFME Transactions, 2019
This research describes an image-based algorithm for a shape recognition of an architectural element from an image. Given an orthophoto of a particular element such as a window, and a query image of the object facade, the algorithm estimates the level of

3D image reconstruction of spinning cone-shaped target

open access: yesThe Journal of Engineering, 2019
By taking full advantage of the similarity of the two-dimensional (2D) imaging result with the target's mapping on the 2D imaging plane, this paper proposes a 3D image reconstruction method for spinning cone-shaped targets, which obtains the true 3D ...

Gait recognition based on shape and motion analysis of silhouette contours [PDF]

open access: yes, 2013
This paper presents a three-phase gait recognition method that analyses the spatio-temporal shape and dynamic motion (STS-DM) characteristics of a human subject’s silhouettes to identify the subject in the presence of most of the challenging factors that

Eye movement patterns during the recognition of three-dimensional objects: Preferential fixation of concave surface curvature minima [PDF]

open access: yes, 2012
This study used eye movement patterns to examine how high-level shape information is used during 3D object recognition. Eye movements were recorded while observers either actively memorized or passively viewed sets of novel objects, and then during a ...

Object recognition using metric shape

open access: yesVision Research, 2012
Most previous studies of 3D shape perception have shown a general inability to visually perceive metric shape. In line with this, studies of object recognition have shown that only qualitative differences, not quantitative or metric ones can be used effectively for object recognition.
