Jul 11, 2019 · I also made a post about Anomaly Detection with Time Series, where I studied internal system behaviors and I provided anomaly forecasts in the future. In this post, I try to solve a different challenge. I change the domain of interest: swapping from Time Series to Images.

Abstract—Detection of anomalies from the medical image dataset improves prognosis by discovering new facts hidden in the data. The present study aims to discuss anomaly detection using autoencoders and convolutional neural networks. The autoencoder identifies the imbalance between normal and abnormal samples.

Part 2, Anomaly detection in images: • The general approach • Subspace / Feature extraction methods • Reference-based methods. Part 3, Anomaly detection by deep learning models: • Transfer Learning / Self-supervised • Autoencoders • Domain based, Generative models

We want to build a machine learning model which is able to classify wall images and detect at the same time where anomalies are located.

Anomaly detection problems are ubiquitous in engineering: the prompt detection of anomalies is often a primary concern, since these might provide precious information for understanding the dynamics of a monitored process and for activating suitable countermeasures. In fact, anomalies are typically the most informative regions in an image (e.g ...

Detecting outliers in images is not an easy task, and can't be done efficiently using some famous outlier detection algorithms.
