In order to improve healthcare services and support clinical professionals, it is important to develop the unobstructive and automatic ADLs monitoring system for healthcare applications. Currently, various works have been developed for the monitoring of daily activities, such as ambulation, kitchen task, food and fluid intake, dressing, and medication intake while only few works paid attention to...
this paper proposes a shape descriptor with a feature graph to highlight both topological structure and geometric features of 3D mesh model. Firstly, the geodesic distance for the computation of an invariant mapping function on a 3D mesh model is adopted to obtain a Reeb graph (RG) skeleton. Secondly, discrete curvature values on the mesh vertices are analyzed to detect the topological changes and...
Wavelet multiresolution analysis allows us to detect edges at different scales, also to obtain other important aspects of the extracted edges. However, due to the usual two-dimensional tensor product, wavelet transform is not optimal for representing images. The main problem in edge detection using wavelet transform is that it can only capture point-singularities, and the extracted edges are not continuous...
In this paper, we suggest and implement a flower image recognition system using Difference Image Entropy (hereinafter, DIE), image rotation, contour and color information of the object. Conventional studies on flower or leaf recognition have restrictions and limitations that include a sharp drop of recognition rate due to the varying positions and number of objects in the original object image. Hence,...
