A Semantic-Enhanced Method Based On Deep SVDD for Pixel-Wise Anomaly Detection

Abstract

Detecting the anomalous information in multimedia is valuable to many computer vision applications. Recently, many pixel-wise methods modeling by deep learning model have been presented, which can be divided in reconstruction-based and distance-based methods. However, reconstruction-based methods suffer from the low precision of pixel reconstructions. Distance-based methods extract the hierarchical features by a pre-trained model, in order to estimate the anomalies by distances between normal and anomalous features. Nevertheless, multi-level features are ignored in these methods, and semantic information is not considered which is important to enhance the description of anomalies. To over-come the problems, we propose a novel semantic-enhanced anomaly detection method based on deep Support Vector Data Description (SVDD). A new semantic correlation module (SCB) is introduced to enhance the semantic information of the feature representations by cosine similarity. Mean-while, the multi-level architecture is utilized to estimate the final pixel-wise anomaly score. Experimental results demonstrate the proposed method outperforms state-of-the-art methods on MVTec and STC dataset.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
