Home Research Teaching ASP Group 新建主栏目 News 名称 17. November 2022:Together with my master student Wu Wenze, we were able to improve the runtime and approximation error of the ORKA method. He will present the latest results on the 9th Annual International Conference on Information Technology and Application (ITA2022). A short paper will also be published in the conference proceedings. You can find a preprint on arxiv (ArXiv link). 16. November 2022:Our latest work "ORKA: Object Reconstruction using K-approximation" has now been published in Inverse Problems (Journal link). The results will also be presented on the 3rd International Conference on Automation, Information and Computing (ISAIC 2022). 1. August 2022:We are now building up a new international group on Applied Signal Processing. If you are a young researcher interested in joining our group, please check the ASP group tab above for more information. We have open Assistant and Associate Professor positions and are also looking for PhD students. About me 名称 I am currently working as Associate Professor at the College of Mathematics, Harbin Institute of Technology.

My research includes topics on Mathematical signal processing, Inverse and NP-hard problems, Greedy methods and efficient algorithm design, (Structured) Sparsity and compressed sensing, Modelling and dictionary design / learning, data compression and denoising, multi-dimensional and scattered data, various applications such as seismic exploration, ptychography, video processing... Research collaborations: We are always looking for new perspectives and creative ideas to advance our research even further. If you are interested and want to collaborate, feel free to contact me. We can provide some funds for a research visit to give our collaboration a kick start. Also check the news category above and the ASP Group tab where we announce open research positions at our institution. Master/PhD supervision: If you are interested in our research, feel free to contact me. We are always looking for dedicated students who want to contribute a Master or PhD thesis.

This lecture is a Master level class. It gives a broad introduction on mathematical signal and image processing starting with the foundations in Fourier- and functional analysis, frame theory, and compressed sensing. Based on this, we discuss different mathematical techniques for problems such as denoising or compression. Later on, we learn how these methods - combined with other algorithsm - can be used to form a data format such as MP3 or JPG2000. Finally in the lecture, we discuss so called data adaptive methods - techniques that can adapt to the given input data. English for Mathematics 1(a) / 2 名称 The lecture series English for Mathematics teaches the basics on English scientific writing. We learn about important grammar rules and commonly made mistakes, how to structure your work, and how to increase readability. Furthermore, we discuss how to proofread your own work and what techniques and software can help in this process. Later on, learn about scientific ethics and publication process. This lecture series has three classes: English for Mathematics 1: The first class is an undergraduate level class. We learn the basics on scientific writing and text structure on simple examples. The class will start on the most basic structure that can appear in a text - a sentence. Already here, many mistakes can be made by using the wrong grammar, phrases, or order of words. The ideas will then be extended to paragraphs, sections, and chapters. At the end of this lecture, you should be able to write simple scientific reports or short papers. English for Mathematics 1a: This class covers the same topics as English for Mathematics 1, but is slightly adapted to fit the needs of the sino-foreign studies. English for Mathematics 2: This class is a Master level class. It covers the more complex topics of scientific writing. We learn about the publication process details such as, how to choose a journal, what is peer review, and how to write a response letter. We also discuss the writing of longer works such as Master or PhD theses. Furthermore, we analyse proofreading techniques and discuss how to check if your work fulfills the ethical and scientific standards. These classes are no basic English language classes. You require sufficiently good English language skills to attend. If you feel unsure about your English level, please refresh your skills beforehand. Master and PhD Supervision 名称 Students intereseted in writing a Master or PhD thesis in Applied Signal Processing may contact me by mail. Please attach your CV and a list of attended lectures including the final grades. Also let me know your preferred research direction or topic. Applied Signal Processing title Signal Processing in applications often requires the expertise on many different fields and topics. One researcher - no matter how talented - can never cover all of it. And so it happens all too often, that we take a problem and simplify and slightly change it until it fits in our field of expertise, thereby loosing much of its original meaning. This problem can only be overcome by uniting researchers on different fields to work together. For this reason, we founded the group on Applied Signal Processing. We want to bring together young researchers from around the world to work on Signal Processing problems from an applicational point of view. The group is currently in its founding state. We are looking for international talents that would like to join us. You should be interested in working on Signal Processing related topics. Feel free to bring your own ideas and applications here, or join us on one of our projects. For more information please see the Open Positions announced below.
