An Accuracy Assessment Measure for Object Based Image Segmentation
Segmentation ASTRO BerkeleyImageSeg Ecognition Definiens
2015/12/17
Traditional approaches to accuracy assessment are inadequate for object oriented image processing. We tested some measures to assess the accuracy of object based image segmentation in a supervised con...
