Osaamistavoitteet

After completing the course the student will know mathematical methods related to image formation. The student will know the basic concepts in compressing data, the importance of the DCT, and some compression standards.
-----
After completing the course the student will be able to make an image to an output device by making good use of the geometric properties of the model, the reflection and material properties of the surface, and locations and properties of the light source. The student will be able to compress and decompress an image e.g. by a JPEG-model in a computer. The student will be able to make good use of MATLAB in problem solving.
