Anet plugin for ImageJ

Process images with pre-trained models for ANNA-PALM, using Tensorflow-java backend.

For more details, please checkout the ANNA-PALM project website and also this repository.

Installation

• Download the Anet-ImageJ plugin: Anet-ImageJ v0.2.2.
• Copy the .jar file into your ImageJ plugin folder (note: Fiji might not work anymore), or directly drag the .jar file into ImageJ (then restart ImageJ).
• You will find an A-net entry in Plugins of ImageJ menu.

Usage

• For the first time, click Setup A-net in the ImageJ Plugins menu ("Plugins => A-Net => Setup"), in the dialog, click the download button and wait until you see a list of models.
• select a model and click ok.
• Open your image, notice that your image size must match the model input, different model can have different input image size. By default, built-in models has the input size of 512x512. If your input image is bigger or smaller than that, you will need to crop or pad with zeros manually in ImageJ.
• Click Run A-net, select input images, and then click ok
• Wait for a while, you should be able to see the result in a pop image window.

Sample images can be downloaded from here: STORM image 1000 frames (used as figure 4 in the paper), cropped to 512x512, full size version (2560x2560), more sample images can be exported from https://annapalm.pasteur.fr.

Use your own model

A set of pre-trained models are provided, a shortcut to download these models is to use the download button in the plugin. You can check directly in a folder named anet-models in your ImageJ folder (next to the plugin folder). You can also download a zip containing the models manually from here.

Model files for the plugin consist of two files: a tensorflow_model.pb file for the frozen model, and a config.json file for the configuration which describe the GUI, input and output of the model.

You can create a new folder (e.g. named "mito_model_v2.3") inside the anet-models folder in ImageJ. Then place your own model file(tensorflow_model.pb) generated with the freeze.py script in ANNA-PALM. To define the GUI and describe the model, you need to manually add a config.json file next to your model file tensorflow_model.pb. To simplify the process, you can just copy an existing config.json file provided by us. In case you have a different input image size, you will need to replace all the 512 into your own size in config.json.

Once you're done, run Setup A-net from the menu and you should be able to see your model shown in the model list. Then select it and process images with your own model.
