Dear Colleagues,

Video processing has always been a frontier topic and an influential research direction in the field of machine computer vision. Most of the research in this field focuses on the use of intelligent technology to analyze the content of video sequences without human intervention, to detect, identify and track suspicious targets in video scenes, and to analyze the behavior of targets and understand the meaning of image content. At present, the method of "deep learning+big data" has achieved excellent recognition performance in many video tasks, and even exceeded the human intelligence level in some tasks. Essentially, knowledge for these video tasks is well estimated and modelled when sufficient data and effective tools are combined. However, in an open environment, due to the uncontrollable quality and content of surveillance data, dynamic changes in categories and data distribution, small amounts of labeled data, noise interference and other reasons, the existing methods show obvious shortcomings in generalization, robustness, interpretability, self-adaptability and other aspects. Therefore, open environment intelligent video processing faces a series of new research problems and needs to explore new theories, models and algorithms.

Therefore, this Special Issue is intended for the presentation of new ideas, advanced theories, and experimental results in the field of video processing, knowledge modeling and uncertainty learning. Topics of interest for this Special Issue include, but are not limited to, the following:

• Video processing technologies, like detection, tracking, segmentation, etc.;
• Video content understanding;
• Natural scene understanding;
• Knowledge discovery and data mining;
• Knowledge graph;
• Multimodal fusion;
• Image processing, recognition and classification;
• Model interpretability;
• Uncertainty learning, open environment incremental learning and continual learning;
• Multi-granularity feature learning;
• Retroactive reasoning.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
