A Formal Evaluation of PSNR as Quality Measurement Parameter for Image Segmentation Algorithms
Fernando A. Fardo, Victor H. Conforto, Francisco C. de Oliveira +1
Quality evaluation of image segmentation algorithms are still subject of debate and research. Currently, there is no generic metric that could be applied to any algorithm reliably.…
Fourier Analysis and q-Gaussian Functions: Analytical and Numerical Results
Paulo Sérgio Silva Rodrigues, Gilson Antonio Giraldi
It is a consensus in signal processing that the Gaussian kernel and its partial derivatives enable the development of robust algorithms for feature detection. Fourier analysis and…
Gradient Vector Flow Models for Boundary Extraction in 2D Images
Gilson A. Giraldi, Leandro S. Marturelli, Paulo S. Rodrigues
The Gradient Vector Flow (GVF) is a vector diffusion approach based on Partial Differential Equations (PDEs). This method has been applied together with snake models for boundary e…
