26 July 2007 Uncertainty in the raster image to vector data conversion of polygon object
Author Affiliations +
In remote sensing image processing, the conversion from raster data to vector data always needs to be made. In previous research of this conversion, researchers mainly focus on the algorithms and efficiency, neglecting the uncertainties in the conversion. This paper reviews the input uncertainty and model uncertainty, and mainly focuses on the analysis of error and uncertainty, together with their propagation in data conversion from raster image to vector. In the conversion, the uncertainty comes from source image data uncertainties, data processing uncertainties and model uncertainties. An experiment was made on analysis of data processing uncertainties in the conversion.
