DSP & Image Processing (Elective)

Introduction to DSP & Image Processing

The aim of this DSP & Image Processing module is to familiarise learners with concepts in digital signal processing and image processing and give the learners practical insights into current developments in the field. Learners should be able to apply these principles to specialist areas to solve bespoke data processing tasks and defend design decisions with well-articulated reports.

Upon successful completion of this module, the learner should be able to:
MIMLO1
Discuss theory regarding digital signal processing and image processing.
MIMLO2
Explain mathematical concepts behind digital signal processing and image processing.
MIMLO3
Write documentation detailing a problem, solution needed, solution provided and an account of how proposed algorithms will meet these needs.

Reassessment Opportunity

Where the combined marks of the assessment and examination do not reach the pass mark the learner will be required to repeat the element of assessment that they failed.   Reassessment materials will be published on Moodle after the Examination Board Meeting and will be aligned to the MIMLOs and learners will be capped at 40% unless there are personal mitigating circumstances.

Aims & Objectives

The DSP & Image Processing module will ensure learners meet the following objectives:

  • Core understanding of digital signal processing and image processing techniques.
  • Advanced mathematical representations of signals and images.
  • Familiarity with industry tools for signal and image processing to perform computational operations.
  • Applying material to real world datasets for complex problem solving.
  • Detailed report writing on algorithm design to present findings.
