Appearance-based material classification after occlusion removal for operation-level construction progress monitoring
… on an existing model-driven appearance-based material classification method for appearance-based construction progress monitoring using 4D BIM and site photologs. Specifically, it introduces a robust occlusion removal algorithm that can lower false positives in material recognition. The method …

Development of Ground-Level Hyperspectral Image Datasets and Analysis Tools, and their use towards a Feature Selection based Sensor Design Method for Material Classification
… have been made in the areas of target classification. Typical to these studies is the use of the Red-Green-Blue (RGB) camera. Separately, in the field of remote sensing, the hyperspectral camera has been used to perform classification tasks on natural and man-made objects from typically …

A material segmentation and classification system
In this thesis, I developed a material segmentation and classification system that takes in images of an object and identifies the material composition of the object's surface. The 3D surface is first segmented into regions that likely contain the same material, using color as a heuristic measure. …

Classifying Sidewalk Materials Using Multi-Modal Data
… environment. Our user study reveals that materials and objects on sidewalks play a crucial role in navigation tasks. Unfortunately, current methods for assessing sidewalk materials are suboptimal, often relying on labor-intensive and expensive manual assessments that fail to capture the …

Improvement proposal to increase productivity of a SME in the primary manufacturing sector using standardized labor and TPM tools
… the second reason was inadequate sorting of raw material, due to the lack of standardized procedures, lack of protocols and disorder in the sorting area. To address these problems, an improvement model was developed based on 5S tools, standardized work and TPM (autonomous and preventive …

Towards low-cost context awareness on smart shelving using passive UHF RFID infrastructure
… for five different tested products. In addition, material classification could be achieved by tag RSSI attenuations. Tests are done between three classes (metal, glass, and plastic), with three objects each class. In the three-location tests, it is possible to clearly differentiate between three …

The Quartz Conundrum : understanding the role of quartz in the composition of late Pleistocene and Holocene lithic assemblages from the Verlorenvlei area, Western Cape
… considered here. Discussions on typology and raw material classification illustrate and attempt to solve problems existing in current systems, and a comprehensive classification scheme for the western Cape area is provided. The use of an innovative analytical technique, in which each raw material …

A population Monte Carlo approach to estimating parametric bidirectional reflectance distribution functions through Markov random field parameter estimation
… be used as features in other high-level vision material or surface classification methods. A variety of probabilistic distances between these features, including the Kullback-Leibler divergence, the Bhattacharyya distance and the Patrick-Fisher distance is used to test the classifiability of the …
