Samseg Aseg Testing
This page documents one front of the work on Samseg, where testing of a version of Samseg operating on T1-weighted input and using the existing RB FS atlas, is conducted to compare its performance against the existing FreeSurfer v6.0 subcortical segmentation processing stream. Initial work was conducted in an evaluation task: SamsegEvaluationMarch2016. The current work pertaining to this page extends that work by:
Creation of a test cycle allowing the comparison of a subject run of Samseg (which is under algorithmic development) to the FS aseg results from v6 for that subject. The test cycle should generate reports on a run, allowing for debug, and evaluation of performance to meet, initially, the aims of the CorticoMetrics grant aims (ie, an accelerated FS based on T1 input only)
- Creation of a data set which includes enough subjects to cover the wide variety of possible inputs. Starting with Buckner40 and ADNI60, and continuing with many others, particularly subjects having extension neck in the FOV, as well as 'tough cases' both in terms of registration and segmentation.
- Documentation of design decisions.
