On‐Device Brain Tumor Classification from MR Images Using Smartphone

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, various deep learning models are trained for brain tumor classification task, and model performances are compared. The performance is further improved by using the proposed preprocessing algorithm before training. The MobileViT model, which is the best‐performing model in terms of balance between inference time and success rate, is integrated ...

AUTOMATIC APPLE TREE BLOSSOM ESTIMATION FROM UAV RGB IMAGERY

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
. Apple trees often produce high amount of fruits, which results in small, low quality fruits. Thinning in apple orchards is used to improve the quality of the apples by reducing the number of flowers or fruits the tree is producing.

Machine Learning Based on Digital Image Colorimetry Driven In Situ, Noncontact Plasma Etch Depth Prediction

open access: yesAdvanced Intelligent Systems, EarlyView.
A real‐time and noncontact approach predicts etch depth in plasma etching using digital image colorimetry and machine learning. Red, green, and blue features from in situ images enable accurate predictions without relying on process parameters. Optical emission spectroscopy provides process diagnostics, ensuring stable operating conditions. This method

Effects of restricting movement between root and canopy populations of woolly apple aphid.

open access: yesPLoS ONE, 2019
Movement of insect pests between spatially subdivided populations can allow them to recolonize areas where local extinction has occurred, increasing pest persistence. Populations of woolly apple aphid (Eriosoma lanigerum [Hausmann]; Hemiptera: Aphididae),
