# Some convolution inversion questions

## TL;DR

This paper explores the challenges and possibilities of inverting convolution operations in image processing, particularly in the context of photographic blurring due to focus errors.

## Contribution

It provides additional insights and complements previous work on convolution-inversion of certain measures, advancing understanding in this area.

## Key findings

- Inversion of convolution can be complex and context-dependent.
- The paper offers new theoretical perspectives on convolution-inversion.
- It discusses limitations and potential methods for inversion in practical scenarios.

## Abstract

Blurring of a photographic image by a wrong focus can be modeled by convolution. Is inversion a possible answer? This paper adds complements to a foregoing paper discussing convolution-inversion of some measures.
