GDV images: Current research and results
We use statistical analysis and machine learning to interpret the GDV coronas of fruits and human’s fingers in order to verify two hypotheses: (A) the GDV images contain useful information about the object/patient and (B) the human bioelectromagnetic field can be influenced by some outside factors. We performed several independent studies, three of which we here briefly describe: (a) recording coronas of berries of different grapevines, (b) detecting the influence of drinking the tap water from ordinary glass and energetic glass K2000, and (c) detecting the influence of natural energy source in Tunjice near Kamnik, Slovenia on the human bioelectromagnetic field. All three studies, as well as some other studies described elsewhere, gave significant results and therefore support both hypotheses
DSR -- A dual subspace re-projection network for surface anomaly detection
The state-of-the-art in discriminative unsupervised surface anomaly detection
relies on external datasets for synthesizing anomaly-augmented training images.
Such approaches are prone to failure on near-in-distribution anomalies since
these are difficult to be synthesized realistically due to their similarity to
anomaly-free regions. We propose an architecture based on quantized feature
space representation with dual decoders, DSR, that avoids the image-level
anomaly synthesis requirement. Without making any assumptions about the visual
properties of anomalies, DSR generates the anomalies at the feature level by
sampling the learned quantized feature space, which allows a controlled
generation of near-in-distribution anomalies. DSR achieves state-of-the-art
results on the KSDD2 and MVTec anomaly detection datasets. The experiments on
the challenging real-world KSDD2 dataset show that DSR significantly
outperforms other unsupervised surface anomaly detection methods, improving the
previous top-performing methods by 10% AP in anomaly detection and 35% AP in
anomaly localization.Comment: Accepted at ECCV202
Cheating Depth: Enhancing 3D Surface Anomaly Detection via Depth Simulation
RGB-based surface anomaly detection methods have advanced significantly.
However, certain surface anomalies remain practically invisible in RGB alone,
necessitating the incorporation of 3D information. Existing approaches that
employ point-cloud backbones suffer from suboptimal representations and reduced
applicability due to slow processing. Re-training RGB backbones, designed for
faster dense input processing, on industrial depth datasets is hindered by the
limited availability of sufficiently large datasets. We make several
contributions to address these challenges. (i) We propose a novel Depth-Aware
Discrete Autoencoder (DADA) architecture, that enables learning a general
discrete latent space that jointly models RGB and 3D data for 3D surface
anomaly detection. (ii) We tackle the lack of diverse industrial depth datasets
by introducing a simulation process for learning informative depth features in
the depth encoder. (iii) We propose a new surface anomaly detection method
3DSR, which outperforms all existing state-of-the-art on the challenging
MVTec3D anomaly detection benchmark, both in terms of accuracy and processing
speed. The experimental results validate the effectiveness and efficiency of
our approach, highlighting the potential of utilizing depth information for
improved surface anomaly detection.Comment: Accepted at WACV 202
Comparative lipidomic study of urothelial cancer models: association with urothelial cancer cell invasiveness
A joint NMR/LC-MS approach allows to establish significant differences in the lipidoma of invasive urothelial carcinoma cells (T24) with respect to noninvasive urothelial cells (RT4)
