Nikon introduces for NIS-Elements, an artificial intelligence algorithm for removing blur from widefield microscope images.

Okt. 12, 2020

Nikon Instruments Inc. is pleased to announce the release of NIS-Elements, a new addition to Nikon’s growing suite of artificial intelligence (AI) tools for microscopy. uses artificial intelligence to automatically remove blur from widefield fluorescence microscope images. utilizes new Nikon technologies executed on graphic processing units (GPUs) to leverage fast and efficient clarity in images normally corrupted by blur due to out-of-focus light. leverages deep learning, a type of artificial intelligence. is pre-trained to recognize fluorescence signal emitted from out-of-focus planes and can computationally remove this haze component from the image, resulting in significantly improved signal-to-noise (S/N) ratio.

Main Features

1. AI algorithm removes out of focus fluorescent signal

In widefield fluorescence microscopy, image clarity can be impaired by out-of-focus signal emitted from above and below the focal plane. Traditionally, deconvolution is used to reassign out-of-focus light, or additional hardware devices such as confocal pinholes used to reject this light. utilizes modern artificial intelligence deep learning technology to recognize out-of-focus light, and can automatically remove this component from widefield fluorescence images.

This new AI-based module enables high-contrast results from any widefield fluorescent sample or acquisition magnification. It can also easily manage removal of heterogeneous scatter while preserving intensity linearity of the underlying data.

2. Simple execution can be used on any widefield 2D or 3D data set obtained from any microscope system, detector, or magnification, without the need for AI training or introduction of bias from complicated user-settings: it has been pre-trained to recognize and remove just the out-of-focus contributions from images and preserve the original details with one click.

3. Applicable to all widefield data sets

No special hardware configuration is required for acquiring images suitable for; any fluorescence widefield images obtained from any detector can be used: including cell cultures, model organisms, tissue sections/slices, or other samples.

Widefield microscopy generally enables fast acquisition speeds and low system costs, and is readily applicable to imaging live specimens. Applying to widefield data sets enables high signal-to-noise ratio results with high contrast while still maintaining the benefits of widefield microscopy.

Computation is fast and can be applied at the experiment time, or later – it can even be applied to archived data for improvement of contrast.
