An automatic data-collection system has been implemented and installed on seven insertion-device beamlines and a bending-magnet beamline at the ESRF (European Synchrotron Radiation Facility) as part of the SPINE (Structural Proteomics In Europe) development of an automated structure-determination pipeline. The system allows remote interaction with beamline-control systems and automatic sample m...
Abstract Building upon fully convolutional networks (FCNs), deep learning-based salient object detection (SOD) methods achieve gratifying performance in many vision tasks, including surface defect detection. However, most existing FCN-based still suffer from the coarse edge predictions. The state-of-the-art employ intricate feature aggregation techniques to refine boundaries, but they are often...
Automatic visual inspection has become an important application of pattern recognition, as it supports the human in this demanding and often dangerous work. Nevertheless, often missing abnormal or defective samples prohibit a supervised learning of defect models. For this reason, techniques known as one-class classification and noveltyor unusual event detection have arisen in the past years. Th...
Due to the direct influence of night vision equipment availability on the safety of night-time aerial reconnaissance, maintenance needs to be carried out regularly. Unfortunately, some defects are not easy to observe or are not even detectable by human eyes. As a consequence, this study proposed a novel automatic defect detection system for aviator's night vision imaging systems AN/AVS-6(V)1 an...
In this paper, we address the problem of design a wavelet lossy image coder that allows preservation of image features such as edges using a modified version of SPIHT algorithm. The modification is made by changing the concept of pixel significance, a coefficient is selected not only by magnitude but as part of a Feature Of Interest (FOI) map obtained with SUSAN edge detector and mapping the co...
