MATH4900 Seminar
MATH4900 Seminar
Course Description:
This seminar course is on variational methods for
segmentation and their applications to different
problems in imaging, including vascular segmentation,
hyper-spectral image classification, and point cloud
classification.
Course Format:
The students will first present some background materials on segmentation
and then be divided into groups to work on different
applications of segmentation. Each group will report their
progress once every two weeks in the 1-hour bi-weekly meetings.
They will have to give two presentations (one at mid-term and
one at end-of-term) about their projects and to write a
report to summarize their projects at the end.
Presentations are to held at the assigned classrooms.
Bi-weekly meetings are in Raymond Chan's office
(LSB 201) and the times are to be arranged between
the teachers and students beforehand.
Lecture Hours: Monday 4:30pm-6:15pm at LSB C1 and Wednesday 12:30-1:15pm
at LSB C4
Office Hours: Every Tuesday 5:30pm-6:15pm, please send me an email
(rchan@math.cuhk.edu.hk)
or call me first (3943-7970), if possible.

Important Remarks:
- CUHK places very high importance on honesty in academic work
submitted by students,
and adopts a policy of zero tolerance on cheating and plagiarism. Any related offence
will lead to disciplinary action including termination of studies at the University.
For information on categories of offenses and types of penalties,
you should consult this link.
- If you are found cheating (in the programming assignment
or the homework assignments),
you will automatically get an F
grade in this course and your act will be
reported
to the Department for necessary disciplinary actions.
- To avoid copying of programs, your programs may be spot-checked,
i.e. you will
be asked questions regarding the statements
in your program.
