TOPICS FOR IT-PROJECT + MSc-THESIS IN THE FIELD OF COLOR SCIENCE
(time period is May/June - 31.12.2007)

In some of the topics there will be a 700 euros/month scholarship.
These topics will be decided later, when InFotonics Center will get 
decisions about the financing. You may apply now according to your 
preferences.

1. Title: Image colorization using spectral colors
   Supervisor: Vladimir Botchko
   Special: Nonlinear dimensionality reduction technique including 
            Locally Linear Embeddings (LLE) and ISOMAP will be tested for 
            purposes of image colorization.

2. Title: Spectral image segmentation using Markov Random Walk Model
   Supervisor: Vladimir Botchko
   Special: Novel algorithm will be tested. Most probable state sequence 
            of features will be defined using Markov Random Walk on data. 
            Then for this sequence initial, transition and emission 
            probabilities will be computed. Then these model parameters 
            will be used in pixel classification (Viterbi algorithm).
  
3. Title: Application for museums: color constancy in image retrieval
   Supervisor: Vladimir Botchko
   Special: Color depends on illumination. This makes it difficult to use 
            in applications. Color constancy algorithm with a chromagenic 
            filter will be tested. Application is either with mobile 
            phones or digital camera.

4. Title: Dimensionality estimation in specral refletances and spectral 
          images
   Supervisor: Vladimir Botchko
   Special: Projections based on nonlinear transformation criteria 
            (ISOMAP) and Spectral Fractal Dimension will be tested to 
            define a dimensionality of spectral data in data sets and 
            images.

5. Title: The measurement accuracy in the 3D spectral imaging
   Supervisor: Birgitta Martinkauppi
   Special: In the color lab there is a new laser-based 3D image retrieval 
            system. One MSc thesis has been done where spectral image was 
            rendered over 3D shape. Now the system's imaging capabilities 
            will be studied further.
 
6. Title: Characterization and tuning of a printer
   Supervisor: Birgitta Martinkauppi
   Special: Accurate and visually good quality printing is an important 
            aspect of a printer. Spectral color methods give a good tool 
            for managing printers. Here, methods for this will be 
            developed.

7. Title: Contrast sensitivity of eye and color diplays
   Supervisor: Hannu Laamanen
   Special: The topic is related to the management system development 
            for different type of display systems

8. Title: Computational determination of spectral sensitivity curves
          of different imaging systems
   Supervisor: Ville Heikkinen
   Special: This is quite mathematical topic which should lead 
            application tests in some of the color group practical 
            projects
