SRG or SNAKE ?

Fabrice Senger
Dear all,

I'm still working on calcium imaging and especially movie analysis.
I clean up the movies and then I simply run find maxima from the binary
menu and save those point to ROI manager, and subsequently to an ROI folder.
Now I would like to use those points as seeds to do region growing so as
to stick to the cells.

Has someone experience with such an approach, could you give me a hint
about tools I could use within imageJ ?

Thank you,

Fabrice.

Cher Fabrice,

Une fois sauvé dans le ROI manager, tu peux faire apparaitre tes points sur
n'importe quel image, sélectionne l'image, puis sur le ROI manager tu peux
faire "Showall" : tes points sont ainsi superposés à l'image mais non
dessinés. Si tu veux les dessiner il faut faire "draw" (attention aux
réglages "Color..." dans le menu d'imageJ et au type de l'image (RGB si tu
dessines avec une couleur autre que noir ou blanc).
Subtilité du ROI manager : si aucune ROI n'est selectionnée il
dessine,sauve, montre, delete,etc... toutes les ROI.
J'espère que cela te sera utile.
