#### Affine transformations

##### Files:
- **affine.png** - test image
- **affine.m** - implementation of affine transformation
- **affine_example.m** - sample of using affine transform

##### Examples:
Examples of affine transformations using by self-implemented or Image Processing Toolbox.

File **affine_example.m** gives examples of code for 3 types of affine transformations:

- **Scale**
- **Shear**
- **Rotation**


#### PCA for face recognition

##### Files:
- **pca.m** - implementation of PCA techique in face recognition 
- **pca_example.m** - examples of using PCA algorithm
- **orl.mat** - data file for demo mode
- **demo.mat** - data file for demo mode
- **digits.mat** - data file for digits mode

##### Examples:
The examples can be run 3 different modes:

- **demo** ```>> pca('demo')``` - run demo mode for precalculated PCA eigenfaces
- **digits** ```>> pca('digits')``` - run PCA algorithm for hand written digits
- **orl** ```>> pca('orl')``` - run PCA algorithm for orl faces db


#### PCA for face identification

##### Files:
- **face_identification.m** - implementation of PCA techique in face identification 
- **group.jpeg** - photo of a group of people
- **single.jpeg** - photo of a single person

##### Examples:
The examples can be run:
```{matlab}
>> face_identification
```
