Thanks to a careful participant, we identified an issue in the released iMED_pe intrinsics. The PNG images in iMED_pe are 600 × 480 per eye, but the original K.txt files were copied from the native 1280 × 1024 calibration without rescaling (btw - the images are already undistorted). To use the release correctly, either: 1. Re-download the updated iMED_pe dataset, or 2. Apply a scale factor of 15/32 ≈ 0.469 to all pixel intrinsics in your local K.txt files: fx, fy, cx, and cy If you downloaded the dataset before this update, please apply the scale factor above. Thanks again to the participant who flagged this. Best, Sierra
