brazilian symposium on computer graphics and image processing (SIBGRAPI)
作者: C.R. Jung Centro de Ciencias Exatas e Tecnológicas UNISINOS Universidade do Vale do Rio dos Sinos Rio Grande do Sul Brazil
We propose a new multiscale segmentation technique based on wavelet decompositions and watersheds. the wavelet transform is applied to the image, producing detail and approximation coefficients. the watershed is appli... 详细信息
