The task of this challenge is to reconstruct CT images of apples with internal defects using as few as possible (simulated) measurements, followed by performing a semantic segmentation of four types of internal defects.

For evaluation, the number of measurements will be reported in combination with the PSNR and SSIM values w.r.t. the ground truth images and the mean Intersection over Union (mIU) w.r.t. the ground truth annotations.
