BSC/MSC Thesis at the ISP -General Remarks
� Bachelor/Master thesis + seminar (SIGN UP !!!)
� Seminar consists of two presentations (midterm and final)
� Goal: Finish your thesis in a reasonable time
� Grade might become worse otherwise
� Make yourself a (realistic) plan before you start!
� Regular meetings with supervisor (Journal!)
� Templates and guidelines how to write your thesis available

ULTRASOUND IMAGE QUALITY ASSESSMENT
Contact: [email protected]
Advantages
• Noninvasive
• Safe
• Low cost
• Portable
• Easy to use
• Widely available
Drawbacks
• Low image resolution
• Artifacts
Aim of the project:
Identify or develop “blind” and “full reference” image quality metrics in order to benchmark image processing systems and algorithms
Combine human expert view of the image quality with mathematical algorithms
Application in phantoms and real anatomical images

AUTOMATIC NEURONAL CLASSIFICATION
Single-unit #1
Single-unit #2
Single-unit #3
Multi-unit activity
Local Field Potential (LFP) &
Background Noise
Extracellular Recording
Neuron
Aim of the project:
Spike Detection Spike Sorting
Hypothesis: The relationship between LFP
and spikes will improve the neuronal
classification that nowadays is based mainly
on spike morphological characteristics
System identification, signal processing, machine learning
