Detailed descriptions of parameters related to light-field forward projection
| Parameters | Description |
|---|---|
| Section A: Rectify and augment high-resolution 3D images | |
| Stack depth | Magnification of the objective lens |
| Axial Overlap | Numerical aperture of the objective lens |
| Axial sampling | Focal distance of the microlens array |
| dx & Nnum | Pitch of microlens array |
| Brightness | Refractive index of the immersion material |
| Rotation Step | Wavelength of emission light |
| Rectify image | Spatial oversampling ratio for computing PSF |
| Rotate | The spacing between of two adjacent planes |
| Complement Insufficient Stacks | The distance between the lowest plane and the focal plane |
| z-min | The distance between the highest plane and the focal plane |
| Nnum | The number of virtual pixels behind one microlens |
| Section B: Forward projection | |
| Brightness Adjust | A parameter to changing the intensity of light field projection images. |
| Poisson Noise | Whether to add Poisson noise on synthetic light field image. |
| Poisson Noise sigma | Whether to add gaussian noise on synthetic light field image. |
| Use GPU | Enable to use GPU for processing |
| Section C: Crop training pairs | |
| Patch size | The size of each block you want to generate. These three numbers represent height, width and depth respectively |
| SumThreshold | A threshold to decide whether to discard cropped patches. If the threshold is larger than the sum of pixel values of a block, this block won’t be saved |
| VarThreshold | Like ‘SumThreshold’, via calculating the variance of a block, this program decides to save this block or not |
