### Color Models
1. RGB model.
2. Pictures in Shades of Grey.
3. HSI model.
4. White balance.
1. Convert 8-bit RGB to Shades of Grey
2. Convert HSI model to RGB
3. Fading Image
* rgb2hsv
* hsv2rgb
* imshow
4. White balance 8-bit RGB image
### Simple Image Processing Techniques
1. Histogram.
2. Spatial filters.
3. Smoothing filters.
4. Sharpening filters.
1. Balance histogram of an image
* imhist
2. Convert image to black & white
* inspect histogram for threshold values
3. Median and Gaussian filters on [brain.gif](https://github.com/z1skgr/MATLAB-image-techniques--analysis/issues/1#issue-1164065378)

* imnoise
5. Noise reduction
* median filter
* average filter (fspecial & imfilter)
### Fourier Transformation 2D
1. Discrete Fourier transformation.
2. Fourier transformation presentation as image.
1. Fourier Transformation on [tools.bmp](https://github.com/z1skgr/MATLAB-image-techniques--analysis/issues/2#issue-1164068316)
* fft2
2.
3. Fourier Transformation
* vertical edge images
* horizontal edges image
4. Fourier Transformation on black square image on size
* 10x10 and reversed 45 angles
* 30x30 and reversed 45 angles
### Image Restoration
1. Wiener Filter(Least Mean Square Filter).
2. Constrained Least Squares Restoration.
1. MSE on Blurring images with Gaussian noise

## Prerequisites
MATLAB environment (or any software using language that is mostly compatible with MATLAB, see [GNU Octave](https://www.gnu.org/software/octave/index)
## How to run
* Navigate path of the script you want to execute
* run(`scriptname.m`)
or
* Execute `Run as script`
