Dataset can be downloaded here: the training, validation, and testing dataset used in the manuscript

The dataset contains:

• 600 microscopic fluorescence images of proflavine-stained oral cancer resections (10×/0.25-NA, manual refocusing)
• 600 histopathology images of healthy and cancerous tissue of human brain, lungs, mouth, colon, cervix, and breast from The Cancer Genome Atlas (TCGA) Cancer FFPE slides.
• 600 INRIA Holiday dataset

In total, it contains 1,800 images (each 1,000 × 1,000 pixels; gray scale)

The 1,800 images were randomly assigned to training, validation, and testing sets that contained 1,500; 150; and 150 images, respectively

Required packages and versions can be found in deepDOF.yml. It can also be used to create a conda environment.

We use a 2 step training process. Step 1 (DeepDOF_step1.py) does not update the optical layer and only trains the U-net. Step 2 (DeepDOF_step2.py) jointly optimizes both the optical layer and the U-net

To test the trained network with an image, use test_image_all_720um.py
