METU Signal Processing Group

Signal processing group studies methods of processing information bearing signals for a particular aim. Signals can be one or multi-dimensional; deterministic or random. The goal can be restoration of a noise corrupted image, compression of a video sequence, generation of alternative viewpoint of a scene, optimal methods of decision under uncertainty (detection and estimation) and efficient usage of resources such as bandwidth, computation or time etc. Also: What is Signal Processing?, Signal Processing and Machine Learning, The Future of Signal Processing Symposium (playlist of youtube videos).

Signal processing tools are widely applied. Some applications are multimedia signal processing (speech, image and video processing), control theory, communications (statistical signal processing, detection/estimation theory), biomedical applications, radar-sonar problems and more.

Signal processing group at METU is specifically working on multimedia signal processing (all aspects), radar signal processing (including SAR imaging and STAP techniques), spectrum estimation techniques, direction of arrival estimation methods.
