# Chapter 3. Image Formation (two weeks)
| # | Topic | Reading | Keywords | Status |
|---|---------------|-------------------|-----------------------------|------|
| 5 | [Image Formation]() | Ma 2004:Ch 3-3.3.1 (SZ 6) | projection, lens/camera | OK |
| 6 | [Camera Calibration]() | Ma 2004:Ch 3.3-3.3.3 | Calibration, Radial Distortion etc. | OK |
| 7 | [More Camera Mathematics]() | Ma 2004:Ch 3.3-3.4 | Radial Distortion, Tangential Distortion | OK |
**Dates** 8-9 and 15 September
# Chapter 4. Feature Tracking (three weeks)
The material will be as given for this chapter, but it will be rearranged.
| # | Topic | Reading | Keywords | Status |
|---|---------------|-------------------|-----------------------------|----|
| 8 (new) | [Image Filters]() | | Convolution. Filters. Blurring. | OK |
| 9 (8-9) | [Corner Detection]() | Ma 2004:Ch 4.3, 4.A (SZ 4) | Calculate Gradient. Harris Feature Detector. |

| 11 (new) | [Project Tracker]() | | **new** Lecture [Multiscale Detection]() |
| 12 (16) | [SIFT]() | | **NB** Feature Matching. Feature Descriptor. |
| 13-14 | *Self-Study* | Continue with [Tracking Features]() |
| 16 (11) | [Edges]() | Ma 2004:Ch 4.4 | |
| 15 | ??? | Recap. |
+ 8 - 16 September
+ 9-12 - 22-23 and 29-30 September
+ 13-14 - 6-7 October - staff seminar - possibly self-managed work only
+ 20-21 - 13-14 October - midterm - regular teaching
*Note* Last year, session 12 was planned Self-Study due to staff seminar.
Session 13-14 became self-study because of sick leave, and negligible
progress was made this week.
*Note from last year*
We should have had one session on blurring filters and similar
techniques from image processing before starting on Corner Detection
(Session 8).
This would have made the introduction of signal differentiation smoother.
# Chapter 5. Projective Reconstruction (two weeks ?)
This plan is tentative and may be shortened as well as rearranged.
| # | Topic | Reading | Keywords |
|---|---------------|-------------------|-----------------------------|
| 17 | [Relative Pose]() | Ma 2004:Ch 5.1 | Triangulation. Relative Pose. Essential Matrix. |
| 18 | [Eight-point algorithm]() | Ma 2004:Ch 5.2 | Calculate Essential Matrix |
| 19 | [Study Technique]() | Ma 2004:Ch 5.1 | Proof reading. |
| 20 | [Synthetic Experiment]() | Ma 2004:Ch 5.1-2 | |
| 21 | [Planar Scenes]()| Ma 2004:Ch 5.3 | |
| 22 | [Epipolar Geometry]()| Ma 2004:Ch 5.1-3 | |
*Notes from last year*
1. [Synthetic Experiment]() should be merged into
[Eight-point algorithm]()
2. [Study Technique]() should probably be done earlier in the semester
3. 3D modelling took a lot of time. Many did not realise that they
needed to find triangles.
Rectangles mixed with triangles caused problems.
4. Generally, the preliminary steps of the exploratory exercises should have been
premade, to save time for the students.
5. Algorithm implementation is difficult and require sample solutions
# New. Machine Learning
TBC
# Chapter 6 and 11. Projective Reconstruction (many weeks)
This will be shortened and probably based on different sources.
| # | Topic | Reading | Keywords |
|---|---------------|-------------------|-----------------------------|
| 23 | [Distorted Space]() | Ma 2004:Ch 6.1-2 | |
| 24 | [Stratified Reconstruction]() | Ma 2005:Ch 6.3-4 | |
| 25 | [Partial Scene Information]() | Ma 2005:Ch 6.5 | |
| 26 | [Real World Reconstruction]() | Ma 2004:Ch 11 | |
*Notes from last year*
1. We can skip [Stratified Reconstruction]()
and [Partial Scene Information]()
2. [Distorted Space]() may be interesting as an introduction to
inner product spaces.
3. What can we make out of [Real World Reconstruction]()?
# Closure/Tentative
