    Deep Learning in Image Cytometry: A Review.2018In: Cytometry Part A, ISSN 1552-4922, E-ISSN 1552-4930Article in journal (Refereed)
    Abstract [en]

    Artificial intelligence, deep convolutional neural networks, and deep learning are all niche terms that are increasingly appearing in scientific presentations as well as in the general media. In this review, we focus on deep learning and how it is applied to microscopy image data of cells and tissue samples. Starting with an analogy to neuroscience, we aim to give the reader an overview of the key concepts of neural networks, and an understanding of how deep learning differs from more classical approaches for extracting information from image data. We aim to increase the understanding of these methods, while highlighting considerations regarding input data requirements, computational resources, challenges, and limitations. We do not provide a full manual for applying these methods to your own data, but rather review previously published articles on deep learning in image cytometry, and guide the readers toward further reading on specific networks and methods, including new methods not yet applied to cytometry data. © 2018 The Authors.

    Convolutional neural networks for false positive reduction of automatically detected cilia in low magnification TEM images2017In: Image Analysis: Part I, Springer, 2017, p. 407-418Conference paper (Refereed)
    Abstract [en]

    Automated detection of cilia in low magnification transmission electron microscopy images is a central task in the quest to relieve the pathologists in the manual, time consuming and subjective diagnostic procedure. However, automation of the process, specifically in low magnification, is challenging due to the similar characteristics of non-cilia candidates. In this paper, a convolutional neural network classifier is proposed to further reduce the false positives detected by a previously presented template matching method. Adding the proposed convolutional neural network increases the area under Precision-Recall curve from 0.42 to 0.71, and significantly reduces the number of false positive objects.

    High-resolution reconstruction by feature distance minimization from multiple views of an object2015In: Proc. 5th International Conference on Image Processing Theory, Tools and Applications, Piscataway, NJ: IEEE , 2015, p. 29-34Conference paper (Refereed)
    Abstract [en]

    We present a method which utilizes advantages of fuzzy object representations and image processing techniques adjusted to them, to further increase efficient utilization of image information. Starting from a number of low-resolution images of affine transformations of an object, we create its suitably defuzzified high-resolution reconstruction. We evaluate the proposed method on synthetic data, observing its performance w.r.t. noise sensitivity, influence of the number of used low-resolution images, sensitivity to object variation and to inaccurate registration. Our aim is to explore applicability of the method to real image data acquired by Transmission Electron Microscopy, in a biomedical application we are currently working on.

    Denoising Benchmark Dataset for Transmission Electron Microscopy ImagesIn: Article in journal (Refereed)
    Abstract [en]

    Benchmark datasets that present the typical characteristics

    of the imaging modality and provide noise-free references

    are critical for meaningful evaluation and selection of suitable

    denoising methods. Image denoising is a well-studied problem

    in consumer cameras, and many denoising benchmark datasets

    are available enhancing the development and evaluation of new

    methods for natural scene photography. For biomedical applications

    in general, and Transmission Electron Microscopy (TEM)

    in particular, very few publicly available denoising benchmark

    datasets exist. In TEM, it is difficult to acquire real noisefree

    reference images; thus this paper presents an approach

    for combining multiple real object images to synthesize realistic

    noise-free images. In addition, a dataset of 60 synthetic cilia crosssection

    TEM images is presented that can serve as noise-free

    references to facilitate quantitative and qualitative evaluation of

    denoising techniques targeted towards structural ultramicroscopy

    applications. The dataset additionally defines masks for features

    of interest for ultrastructural analysis of cilia. Such masks enable

    performance evaluation focusing on the ability of the denoising

    techniques to restore/preserve fine details of specific interest. The

    paper ultimately presents a study comparing four commonly used

    denoising techniques at four characteristic noise levels observed

    at different exposure settings of TEM. The results demonstrate

    the usefulness of the proposed dataset in the selection of a suitable

    denoising method.

    super-resolution Reconstruction of Transmission Electron Microscopy Images using Deep Learning2019Conference paper (Refereed)
    Abstract [en]

    Deep learning techniques have shown promising outcomes

    in single image super-resolution (SR) reconstruction

    from noisy and blurry low resolution data. The SR reconstruction

    can cater the fundamental limitations of transmission

    electron microscopy (TEM) imaging to potentially attain

    a balance among the trade-offs like imaging-speed, spatial/

    temporal resolution, and dose/exposure-time, which is

    often difficult to achieve simultaneously otherwise. In this

    work, we present a convolutional neural network (CNN)

    model, utilizing both local and global skip connections, aiming

    for 4 SR reconstruction of TEM images. We used exact

    image pairs of a calibration grid to generate our training and

    independent testing datasets. The results are compared and

    discussed using models trained on synthetic (downsampled)

    and real data from the calibration grid. We also compare the

    variants of the proposed network with well-known classical

    interpolations techniques. Finally, we investigate the domain

    adaptation capacity of the CNN-based model by testing it

    on TEM images of a cilia sample, having different image

    characteristics as compared to the calibration-grid.

    Automated detection of cilia in low magnification transmission electron microscopy images using template matching2016In: Biomedical Imaging (ISBI), 2016 IEEE 13th International Symposium on, IEEE, 2016, p. 386-390Conference paper (Other academic)
    Abstract [en]

    Ultrastructural analysis using Transmission Electron Microscopy (TEM) is a common approach for diagnosing primary ciliary dyskinesia. The manually performed diagnostic procedure is time consuming and subjective, and automation of the process is highly desirable. We aim at automating the search for plausible cilia instances in images at low magnification, followed by acquisition of high magnification images of regions with detected cilia for further analysis. This paper presents a template matching based method for automated detection of cilia objects in low magnification TEM images, where object radii do not exceed 10 pixels. We evaluate the performance of a series of synthetic templates generated for this purpose by comparing automated detection with results manually created by an expert pathologist. The best template achieves a detection at equal error rate of 47% which suffices to identify densely populated cilia regions suitable for high magnification imaging.

    Enhancement of cilia sub-structures by multiple instance registration and super-resolution reconstruction2017In: Image Analysis: Part II, Springer, 2017, p. 362-374Conference paper (Refereed)
    Abstract [en]

    Ultrastructural analysis of cilia cross-sectional images using transmission electron microscopy (TEM) assists the pathologists to diagnose Primary Ciliary Dyskinesia, a genetic disease. The current diagnostic procedure is manual and difficult because of poor signal-to-noise ratio in TEM images. In this paper, we propose an automated multi-step registration approach to register many cilia cross-sectional instances. The novelty of the work is in the utilization of customized weight masks at each registration step to achieve good alignment of the specific cilium regions. Registration is followed by super-resolution reconstruction to enhance the substructural information. Landmarks matching based evaluation of registration results in pixel alignment error of 2.35±1.82" role="presentation">2.35±1.82 pixels, and the subjective analysis of super-resolution reconstructed cilium shows a clear improvement in the visibility of the substructures such as dynein arms, radial spokes, and central pair.
