A Machine Vision System for Robust Sorting of Herring Fractions
Guttormsen, Erik; Toldnes, Bendik; Bondø, Morten Steen; Eilertsen, Aleksander; Gravdahl, Jan Tommy; Mathiassen, John Reidar Bartle (Journal article, 2016)Among the rest raw material in herring (Clupea harengus) fractions, produced during the filleting process of herring, there are high-value products such as roe and milt. As of today, there has been little or no major effort ... -
Bin Picking of Reflective Steel Parts using a Dual-Resolution Convolutional Neural Network Trained in a Simulated Environment
Dyrstad, Jonatan Sjølund; Bakken, Marianne; Grøtli, Esten Ingar; Schulerud, Helene; Mathiassen, John Reidar Bartle (Journal article; Peer reviewed, 2018)We consider the case of robotic bin picking of reflective steel parts, using a structured light 3D camera as a depth imaging device. In this paper, we present a new method for bin picking, based on a dual-resolution ... -

Gradual Reduction in Sodium Content in Cooked Ham, with Corresponding Change in Sensorial Properties Measured by Sensory Evaluation and a Multimodal Machine Vision System
Greiff, Kirsti; Mathiassen, John Reidar Bartle; Misimi, Ekrem; Hersleth, Margrethe; Aursand, Ida Grong (Journal article; Peer reviewed, 2015)The European diet today generally contains too much sodium (Na+). A partial substitution of NaCl by KCl has shown to be a promising method for reducing sodium content. The aim of this work was to investigate the sensorial ... -
Grasping virtual fish: A step towards deep learning from demonstration in virtual reality
Dyrstad, Jonatan Sjølund; Mathiassen, John Reidar Bartle (Journal article; Peer reviewed, 2018)We present an approach to robotic deep learning from demonstration in virtual reality, which combines a deep 3D convolutional neural network, for grasp detection from 3D point clouds, with domain randomization to generate ... -
Lønnsom foredling av sjømat i Norge
Digre, Hanne; Bar, Eirin Marie Skjøndal; Mathiassen, John Reidar Bartle; Standal, Dag; Grimsmo, Leif; Henriksen, Kristian; Romsdal, Anita; Asche, Frank (Research report, 2014)Automatisering og robotisering av produksjonsprosesser forventes å få en sentral plass i samfunnet. I en utredning fra Stiftelsen for Strategisk Forsking i Sverige, forventes det at i løpet av ... -
Teaching a Robot to Grasp Real Fish by Imitation Learning from a Human Supervisor in Virtual Reality
Dyrstad, Jonatan Sjølund; Øye, Elling Ruud; Stahl, Annette; Mathiassen, John Reidar Bartle (Journal article, 2018)We teach a real robot to grasp real fish, by training a virtual robot exclusively in virtual reality. Our approach implements robot imitation learning from a human supervisor in virtual reality. A deep 3D convolutional ...
