17 p, 2.1 MB An Interactive Algorithm for Image Smoothing and Segmentation / Carneiro de Andrade, Marcos (Centro de Desenvolvimento da Tecnologia Nuclear (Belo Horizonte, Brasil))
This work introduces an interactive algorithm for image smoothing and segmentation. A non-linear partial differential equation is employed to smooth the image while preserving contours. The segmentation is a region-growing and merging process initiated around image minima (seeds), which are automatically detected, labeled and eventually merged. [...]
