From Nano to Macro: Overview of the IEEE Bio Image and Signal Processing Technical Committee

no code implementations31 Oct 2022 Selin Aviyente, Alejandro Frangi, Erik Meijering, Arrate Muñoz-Barrutia, Michael Liebling, Dimitri Van De Ville, Jean-Christophe Olivo-Marin, Jelena Kovačević, Michael Unser

The Bio Image and Signal Processing (BISP) Technical Committee (TC) of the IEEE Signal Processing Society (SPS) promotes activities within the broad technical field of biomedical image and signal processing.

Estimating Nonplanar Flow from 2D Motion-blurred Widefield Microscopy Images via Deep Learning

2 code implementations14 Feb 2021 Adrian Shajkofci, Michael Liebling

We estimated the velocity vector field from the local estimation of the blur model parameters using an deep neural network and achieved a prediction with a regression coefficient of 0. 92 between the ground truth simulated vector field and the output of the network.

Spatially-Variant CNN-based Point Spread Function Estimation for Blind Deconvolution and Depth Estimation in Optical Microscopy

1 code implementation8 Oct 2020 Adrian Shajkofci, Michael Liebling

Following microscope-specific calibration, we further demonstrate that the recovered PSF model parameters permit estimating surface depth with a precision of 2 micrometers and over an extended range when using engineered PSFs.

Depth Estimation

Free annotated data for deep learning in microscopy? A hitchhiker's guide

no code implementations8 Oct 2020 Adrian Shajkofci, Michael Liebling

In microscopy, the time burden and cost of acquiring and annotating large datasets that many deep learning models take as a prerequisite, often appears to make these methods impractical.

DeepFocus: a Few-Shot Microscope Slide Auto-Focus using a Sample Invariant CNN-based Sharpness Function

1 code implementation2 Jan 2020 Adrian Shajkofci, Michael Liebling

Autofocus (AF) methods are extensively used in biomicroscopy, for example to acquire timelapses, where the imaged objects tend to drift out of focus.

Semi-Blind Spatially-Variant Deconvolution in Optical Microscopy with Local Point Spread Function Estimation By Use Of Convolutional Neural Networks

2 code implementations20 Mar 2018 Adrian Shajkofci, Michael Liebling

We present a semi-blind, spatially-variant deconvolution technique aimed at optical microscopy that combines a local estimation step of the point spread function (PSF) and deconvolution using a spatially variant, regularized Richardson-Lucy algorithm.
