LEA-Net: Layer-wise External Attention Network for Efficient Color Anomaly Detection

no code implementations12 Sep 2021 Ryoya Katafuchi, Terumasa Tokunaga

Through extensive experiments on PlantVillage, MVTec AD, and Cloud datasets, we demonstrate that the proposed layer-wise visual attention mechanism consistently boosts anomaly detection performances of an existing CNN model, even on imbalanced datasets.

Image-based Plant Disease Diagnosis with Unsupervised Anomaly Detection Based on Reconstructability of Colors

no code implementations29 Nov 2020 Ryoya Katafuchi, Terumasa Tokunaga

Although supervised image classifiers based on deep learning can be a powerful tool for plant disease diagnosis, they require a huge amount of labeled data.

SPF-CellTracker: Tracking multiple cells with strongly-correlated moves using a spatial particle filter

no code implementations26 Aug 2015 Osamu Hirose, Shotaro Kawaguchi, Terumasa Tokunaga, Yu Toyoshima, Takayuki Teramoto, Sayuri Kuge, Takeshi Ishihara, Yuichi Iino, Ryo Yoshida

Data types to which the method is applicable are characterized as follows: (i) cells are imaged as globular-like objects, (ii) it is difficult to distinguish cells based only on shape and size, (iii) the number of imaged cells ranges in several hundreds, (iv) moves of nearly-located cells are strongly correlated and (v) cells do not divide.
