Understanding of image processing and suitable.
2D and 3D transforms.

Subject-specific Skills:

Key Skills:

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

Teaching by lectures and tutorials which are supported by a laboratory programme outside this module.
Written examinations are appropriate because of the wide range of in-depth, analytical material that is covered.
Theoretical coursework contributes a formative element to the module and aids the acquisition of subject-specific and key skills.
