Scientific activity

My main research interest is in the field of image processing.

PhD thesis: Contributions to image analysis, processing and representation (original title, in romanian: Contribuţii în analiza, prelucrarea şi reprezentarea imaginilor), defended on February 20, 2006.

Preparation stage:

• Gestiunea formelor grafice (PS.gz(114kB), PDF(297kB) )
• Transfromări spectrale ale imaginilor (PS.gz(95kB), PDF(258kB) )
• Recunoaşterea obiectelor în imagini (PS.gz(94kB), PDF(207kB) )
