Currently, image annotation masks can only be created inside Pix4Dmapper (to the best of my knowledge).
I would really like to see a function where externally created masks can be imported e.g. like a black and white .png/.jpg image as is possible in Agisoft Metashape.
For example, I work with coral reef imagery suffering from glint and breaking waves.
Both things are easily selected with a single luminance mask applied to all images in Lightroom/Photoshop.
These masks can be exported as a separate black and white image.
Trying to recreate these mask in Pix4D’s annotation tool would take hours and hours.
However, currently there is no option to import these masks into Pix4D.
I tried copying them into the project_name\1_initial\project_data\segments
using a image_name_labels.png format as referenced here: Annotate Mask/Global Mask - #3 by Ramiro_Massa
However, this crashes the annotation tool and does not seem to work.
