TL;DR: It is shown that a CNN can assess the human tumor microenvironment and predict prognosis directly from histopathological images and was an independent prognostic factor for overall survival in a multivariable Cox proportional hazard model.
Journal ArticleDOI
Colour calibration of a laboratory computer vision system for quality evaluation of pre-sliced hams.
TL;DR: The calibrated laboratory CVS, implemented with a low-cost digital camera, exhibited reproducible colour signals in a wide range of colours capable of pinpointing regions-of-interest and allowed the extraction of quantitative information from the overall ham slice surface with high accuracy.
Journal ArticleDOI

TL;DR: Comparison of the post‐ischemic neuroinflammation among murine permanent and transient middle cerebral artery occlusion (MCAO) models shows Neuroinflammation is more pronounced after permanent electrocoagulatory MCAO compared with 30 minutes and 90 minutes filament‐M CAO.
Journal ArticleDOI
Predicting the ripening of papaya fruit with digital imaging and random forests
TL;DR: Papaya grading is performed manually which may lead to misclassifications, resulting in fruit boxes with different maturity stages, but can mature into an industrial application with the right integration framework.
