# Welcome to PERI’s documentation!¶

Getting Started

For an introduction to how `peri`

works and how to use it, see the
walkthrough.

Parameter Extraction from Reconstruction of Images (PERI) is a package that extracts features from microscope images by fitting a physics-based model to data. It is a set of models and components that are used to recreate the physics of image formation in order to extract desired quantities such as particle sizes and positions at the information theoretic limit. While a very general software package, right now the primary model currently implemented is that of 3D confocal microscopes, particularly of the line and point scan varieties.

- What is PERI?
- Take a microscope image.
- Create a mathematical model of the image formation process.
- Fit that mathematical model to the image.
- If the fit is not good, improve the mathematical model.
- If the fit is good, use the extracted information from the fit.
- Making this faster
- Checking your model even more
