Reliability of image sensors is limited by the continuous development of in-field defects. Laboratory calibration on 21 DSLRs has revealed hot pixels as the main defect type found in all tested cameras, with 78% of the identified defects having a time-independent offset. The expanded ISO range that exists in new cameras enables natural light photography. However, the gain applied to all pixels ...

We consider the defect size distributions at different stages of damage evolution, from the initial stage of defect nucleation and accumulation, through the intermediate stage of defect propagation and into the final stage leading to the appearance of the major crack. Critical events considered in this context are related to (a) the formation of microcracks exceeding the structural threshold as...

In this study, UAVs were used to collect data of distribution line resources, and defects in equipment construction process identified through deep learning. Different algorithms are identify the process. The research will ultimately support regional synchronization online development for intelligent automatic acceptance wire UAV.

Tire defects are crucial for safe driving. Specialized experts or expensive tools such as stereo depth cameras and gages usually used to investigate these defects. In image processing, feature extraction, reduction, classification presented three challenging symmetric ways affect the performance of machine learning models. This paper proposes a hybrid system cracked tire detection based on adap...

We present an experimental study that explores how head tracking and stereo viewing affect user performance when rotating 3D virtual objects using isomorphic and non-isomorphic rotation techniques. Our experiment compares isomorphic with non-isomorphic rotation utilizing four different display modes (no head tracking/no stereo, head tracking/no stereo, no head tracking/stereo, and head tracking...

This article presents an investigation study of stereo-based 3D surface reconstruction algorithms by providing an overview of the diierent approaches that have been investigated in the stereo literature during the last decade. This study considers only the two-views plain stereo algorithms and provides another classiication for the stereo approaches based on the features used in the stereo lite...
