Video Summarization based on Motion Detection for Surveillance Systems
TL;DR: An approach based on the combining of the background subtraction and the Structure-Texture-Noise Decomposition that is effective and accurate for moving objects detection and yields a good summarization of the video sequence.
Statistical tools for weld defect evaluation in radiographic testing
TL;DR: In this article, the authors developed and implemented algorithms based on statistical approaches for segmentation and classification of the weld defects, and a comparative study of the various segmentation methods was performed to demonstrate the advantages of the ones in comparison with the others giving to the most optimal combinations.
