New Methods for Leak Detection and Contour Correction in Seeded Region Growing Segmentation
Medicine Application Segmentation
2015/7/14
Segmentation, i.e. the labelling of objects in image data, is a crucial step in many medical imaging processing tasks, e.g. operation
planning, radio therapy or diagnostics. Seeded region growing is ...
A Comparison of Segmentation Programs for High Resolution Remote Sensing Data
Automation Land cover Classification
2015/7/9
Methods of image segmentation become more and more important in the field of remote sensing image analysis – in particular due to
the increasing spatial resolution of imagery. The most important fact...
We present an investigation on the use of Tensor Voting for categorizing LIDAR data into outliers, line elements (e.g.
high-voltage power lines), surface patches (e.g. roofs) and volumetric elements ...
SAR IMAGE SEGMENTATION THROUGH B-SPLINE DEFORMABLE CONTOURS AND FRACTAL DIMENSION
