Towards drift-free high-throughput nanoscopy through adaptive intersection maximization

Single-molecule localization microscopy (SMLM) often suffers from suboptimal resolution due to imperfect drift correction. Existing marker-free drift-correction algorithms often struggle to reliably track high-frequency drift and lack the computational efficiency to manage large, high-throughput localization datasets. We present an adaptive intersection maximization-based method (AIM) that leverages the entire dataset's information content to minimize drift correction errors, particularly addressing high-frequency drift, thereby enhancing the resolution of existing SMLM systems. We demonstrate that AIM can robustly and efficiently achieve an angstrom-level tracking precision for high-throughput SMLM datasets under various imaging conditions, resulting in an optimal resolution in simulated and biological experimental datasets. We offer AIM as simple and model-free software for instant resolution enhancement with standard CPU devices., We provided the following dataset.

## AIM

Adaptive Intersection Maximization (AIM) is a high-speed drift correction algorithm for single molecule localization microscopy.

The details are presented in our paper entitled \"Towards drift-free high-throughput nanoscopy through adaptive intersection maximization\".

All the codes under \DME_RCC are from [https://github.com/qnano/drift-estimation](https://github.com/qnano/drift-estimation) published in Jelmer Cnossen, Tao Ju Cui, Chirlmin Joo, and Carlas Smith, \"Drift correction in localization microscopy using entropy minimization,\" Opt. Express 29, 27961-27974 (2021).

## Hardware requirement:

AIM requires only a standard computer with a minimum of 16GB of RAM.
RCC and DME require a minimum of 32GB of RAM to handle the large datasets generated from systems with a large field of view (e.g., 2048 x 2048 pixels).

## Software requirement:

The provided codes have been tested on MATLAB ve...
