Improving Video Retrieval by Adaptive Margin
Proceedings of the 44th International ACM SIGIR Conference on Research and Development in Information Retrieval, 2021 Video retrieval is becoming increasingly important owing to the rapid emergence of videos on the Internet. The dominant paradigm for video retrieval learns video-text representations by pushing the distance between the similarity of positive pairs and that of negative pairs apart from a fixed margin.

Adaptive Marginal Median Filter for Colour Images [PDF]
Sensors, 2011 This paper describes a new filter for impulse noise reduction in colour images which is aimed at improving the noise reduction capability of the classical vector median filter. The filter is inspired by the application of a vector marginal median filtering process over a selected group of pixels in each filtering window.
