Comparison of 3D Processing Times in Seconds and Segmentation Quality.

Processing time in seconds and subjective quality measure of five algorithms implemented in C/C++ with respect to the image size. Missing values indicate either memory consumption of more than 32 GB (OTSUWW, GAC, GC) or incapabilities of the software (GFT). Tiled processing was disabled for our implementations to ensure comparable memory limitations. Performance of the algorithms was tested without using threads and with 8 threads where possible (indicated by *). Due to a lack of 3D ground truth for the DSLM images, we provide a qualitative evaluation using five categories .
