Closed Contour Shape Descriptors with High Compression Properties Based on the Discrete Hartley Transform

Martí i Puig, Pere; Reig Bolaño, Ramon; Danés Garolera, Jaume (IOP Press, 2013)

The quantitative analysis of shapes is required in some research fields, such as taxonomy, agronomy, ecology, medicine, among others. The quantification of an object shape, or a biological entity shape as extension, is ...
Features extraction based on the Discrete Hartley Transform for closed contour

Martí i Puig, Pere; Reig Bolaño, Ramon; Danés Garolera, Jaume (IOS Press, 2015)

In this paper the authors propose a new closed contour descriptor that could be seen as a Feature Extractor of closed contours based on the Discrete Hartley Transform (DHT), its main characteristic is that uses only half ...
Parameterization of written signatures based on EFD

Martí i Puig, Pere; Danés Garolera, Jaume; Solé-Casals, Jordi (Springer, 2013)

In this work we propose a method to quantify written signatures from digitalized images based on the use of Elliptical Fourier Descriptors (EFD). As usually signatures are not represented as a closed contour, and being ...
