You can choose any topic related to digital signal processing. However, the topic should be approved by the instructor. Each group consists of three students (in exceptional cases, two students). Single-person projects are strongly discouraged and are subject to the instructor's approval. Students can not work on the same or very similar research topics. Email the instructor as soon as you have decided on your topic, so that your priority is reserved. Students who need help with choosing a topic for the course project are encouraged to consult with the instructor. Hossein Sameti, CE, SUT, Fall 1992 12 Any topic related to DSP is acceptable. However, make sure that the topic is realistic and the work is doable in a short period. Some research areas: ◦ Medicine: analysis of biosignals, medical imaging,… ◦ Speech, music, and audio: Speech recognition, speech verification, music synthesis, music emotion recognition, … ◦ Security: biometrics, surveillance,… ◦ Data management: data storage, compression, and retrieval,… ◦ Financial: financial data analysis ◦ Image processing: image denoising, image manipulation… ◦ Computer/Machine vision: automatic object recognition and identification,… Hossein Sameti, CE, SUT, Fall 1992 13 The break-down of the project evaluation is as follows: ◦ ◦ ◦ ◦ Quality of the project: 40% Quality of the final report: 25% Oral presentation: 25% Project proposal: 10% Due Dates (strict deadlines): ◦ Project proposal: 5 Aban 1392 ◦ Final report: your presentation date Hossein Sameti, CE, SUT, Fall 1992 14 The project proposal includes a summary of the area you want to work on, the context, the significance, and the methodology. Clarify your work plan and schedule and what results are to be obtained. Please note that ◦ A project proposal should include the title of the project, the name of the students who are working on the project and a brief description of the project. ◦ Project proposals need to be approved before you start the course project. ◦ Proposals should be returned on the due date in a written format. ◦ Proposals can take up to two pages (single column, single-line spacing). You can include references and figures if needed. ◦ Proposals will be graded and relevant feedback will be given to you. Course project descriptions from previous years and a sample proposal will be posted on the course webpage later this week. The sample proposal can be used as the template. Hossein Sameti, CE, SUT, Fall 1992 15 It is recommended to use available software and Matlab functions. Visit Matlab Central- File Exchange to find the files or packages that are developed by other users. However, you should check these files to make sure that they work properly. Guidelines for writing clean and efficient code will be posted on the course website later this week. Please properly cite the code and the work of others if you are using them. If you use others’ code, you need to clearly state your contribution in your project report. Your own code should be written in a clear manner and should be supplied as supplementary material. Hossein Sameti, CE, SUT, Fall 1992 16 The written report is expected to be 12-15 single-column, 1.5 line spacing pages. Reports are to be submitted in both soft copy and hard copy on the due date. You can provide clearly-explained and organized supplementary material separately (images, movies, etc). Hossein Sameti, CE, SUT, Fall 1992 17 The report must follow the guidelines for an IEEE journal/conference proceedings paper (the template can be found on the course webpage). A typical report is a single document file that includes the following: ◦ title, author, affiliation ◦ abstract, keywords ◦ introduction (application and problem description, background, related work/literature survey, short summary of submitted work,...) ◦ description of data, images, etc. ◦ methods (the proposed method, algorithmic details, equations/formula, pseudocode, explanatory figures,...) ◦ results (qualitative and quantitative, figures and tables,...) ◦ summary and conclusions (summarize main contribution, problems encountered, possible future work,...) ◦ references Hossein Sameti, CE, SUT, Fall 1992 18 An oral presentation is also required ◦ Each project will be allocated 10 minutes: it includes setting up the computer and presenting the oral presentation. Questions and discussion will follow for 2 minutes. ◦ Students are required to attend project presentations. Hossein Sameti, CE, SUT, Fall 1992 19 Midterm exam accounts for 25% and the final exam accounts for 40% of the overall mark. Date of the mid-term: Tuesday 21 Aban at 5 PM The emphasis of the final exam will be on the topics covered after the mid-term. You can bring one piece of paper (double-sided) to the midterm exam and two pieces of paper (double-sided) to the final exam. You can write anything on it (formulae, figures, drawings, solutions to the problems, text, poems, etc!). Hossein Sameti, CE, SUT, Fall 1992 20 Questions or comments?
