Meanings of manual delineation in English

Four PET-based contours ( manual delineation, two threshold methods and a source-to-background ratio method) were delineated.

The accuracy and speed of the proposed method are quantitatively validated by comparing automatic segmentation results with the manual delineation results.

However, validation is often limited to comparison with manual delineation by overlap-based measures, which is limited in characterizing morphological and topological differences.

After tissue types were identified using an automated segmentation process, the dlPFC was measured in both hemispheres using manual delineation based on anatomical landmarks.

Manual delineation of separate pathologies is infeasible in large studies of stroke that include thousands of patients.

We validate the proposed technique by comparing our segmentation results with corresponding manual delineations in ultra-high resolution MRI scans of five individuals.

The resulting segmentations correspond well to manual delineations of eight axial slices per scan, with an average Dice similarity coefficient of 0.933.
