Image-based Deep Learning for the time-dependent prediction of fresh concrete properties

no code implementations9 Feb 2024 Max Meyer, Amadeus Langer, Max Mehltretter, Dries Beyer, Max Coenen, Tobias Schack, Michael Haist, Christian Heipke

In this paper, a method is presented that makes it possible to predict the properties of fresh concrete during the mixing process based on stereoscopic image sequences of the concretes flow behaviour.

ConsInstancy: Learning Instance Representations for Semi-Supervised Panoptic Segmentation of Concrete Aggregate Particles

1 code implementation10 Apr 2022 Max Coenen, Tobias Schack, Dries Beyer, Christian Heipke, Michael Haist

In particular, we are able to show that by leveraging completely unlabeled data in our semi-supervised approach the achieved overall accuracy (OA) is increased by up to 5% compared to an entirely supervised training using only labeled data.

Learning to Sieve: Prediction of Grading Curves from Images of Concrete Aggregate

no code implementations7 Apr 2022 Max Coenen, Dries Beyer, Christian Heipke, Michael Haist

A large component of the building material concrete consists of aggregate with varying particle sizes between 0. 125 and 32 mm.

Semi-Supervised Segmentation of Concrete Aggregate Using Consensus Regularisation and Prior Guidance

no code implementations22 Apr 2021 Max Coenen, Tobias Schack, Dries Beyer, Christian Heipke, Michael Haist

To overcome the limitations of standard consistency training, we propose a novel semi-supervised framework for semantic segmentation, introducing additional losses based on prior knowledge.

CNN-based Cost Volume Analysis as Confidence Measure for Dense Matching

no code implementations17 May 2019 Max Mehltretter, Christian Heipke

Due to its capability to identify erroneous disparity assignments in dense stereo matching, confidence estimation is beneficial for a wide range of applications, e. g. autonomous driving, which needs a high degree of confidence as mandatory prerequisite.

A two-layer Conditional Random Field for the classification of partially occluded objects

no code implementations11 Jul 2013 Sergey Kosov, Pushmeet Kohli, Franz Rottensteiner, Christian Heipke

Conditional Random Fields (CRF) are among the most popular techniques for image labelling because of their flexibility in modelling dependencies between the labels and the image features.
