error about "No unprojected gaze lines or ellipse centres were added (not yet initalized). Use add_to_fitting() function to add them first"

[SophieChang66]

hello, thank you for sharing your project. I installed it as read.me, and started fit step, but I got the error "No unprojected gaze lines or ellipse centres were added (not yet initalized). Use add_to_fitting() function to add them first ". Besides, i want konw that whether can i utilize the project to estimate gaze of video from DMS(driver monitor system) NIR camera ?

Hello!

From the error message, it seems that the program has correctly been installed. However, it cannot detect the pupil from your video. For identifying the problem, could you share the video clip that you use? (if it is not possible, a video frame would also be helpful.)

About the gaze estimation from NIR camera, the network detects pupil from images that cover mainly a single eye area without other facial/body features (e.g. images similar to the first figure in README.md, because they are what the network was trained on. If the DMS NIR video contains other body parts, then it is unlikely that this project can be utilized.
