I need to annotate some images to train a neural network to segment my data. Do you know any tool that would allow me to semi-automate this process and then manually correct it? What I need to obtain is a masked stack for every training stack (my data are in 3D) every all pixel of an object, i.e. a nucleus, are labeled with an integer different from other objects (and the background corresponds to 0). To do that, i was using Labkit and manually annotating every nucleus, but it is too much time and effort.
Do you have some advice to speed up this process?
