Algorithm Submission

The SPIDER challenge consists of two phases: a validation and tuning phase, and a testing phase. 

Validation and Tuning phase:

• One submission per user per week
• Submission is evaluated on 5 lumbar MRI series from all different data providers 

Testing phase:

• One submission per user per month with a maximum of 5 submissions 
• Submission is evaluated on the hidden test set which contains 97 lumbar MRI series from 39 studies 

To participate in this segmentation challenge, participants must provide a built image containing their method, which should be uploaded as an algorithm to the Grand Challenge platform. The output of the algorithm should be a singular segmentation mask with a similar size and direction as the input image in .mha format.

A blank template repository is provided to assist with the algorithm submission process. Participants are encouraged to read the README file for more information on how to use this repository.

Documentation on how to upload an algorithm to the Grand Challenge platform can be found here. Be sure to use the following input and output interfaces:

• Input interface: sagittal-spine-mri
• Output interface: sagittal-spine-mr-segmentation

Note that the output segmentation should be datatype int8 or uint8, containing only positive numbers
