 Image Processing Using MATLAB   
 


This repository contains image processing code. The codes are designed to recognise objects using HSV values from real-time video data.

##  v.2017.1.0.0 

The GUI is created using Guide.

The code is rather outdated. However, I am still publishing this for future reference and developments. I accomplished this in 2017-2018, and there have been many improvements and optimizations since then. The new approach is updated in the 2021 folder.

  



## Issues

These functions are slow and time-consuming; any alternative would be greatly appreciated. 


### Issue [#1]( https://github.com/sahq-azhar/MATLAB-Image_Processing/issues/1)

#### Slider Callback Function for saving in [jumma.m](https://github.com/sahq-azhar/MATLAB-Image_Processing/blob/0d2d4a87f790af99a2afabff9eb14113adf14b26/2017/1_Getting%20HSV%20values%20from%20slider-GUI/jumma.m#L84-L88)

The following code retrieves values from the GUI Slider and passes them to the corresponding HSV values in the link.m file. 


save function saves the value of the slider in a .txt file that can be called in the other .m file 


```matlab

h1=get(handles.slider1,'value');

set(handles.edit1,'string',h1);

%h1 = get(hObject,'Value')

% print h1

save ('h1.txt','h1','-ascii')

```

#### Load in [link.m](https://github.com/sahq-azhar/MATLAB-Image_Processing/blob/210f26366a2d4df259afa53062949875da368dc5/2017/1_Getting%20HSV%20values%20from%20slider-GUI/link.m#L11-L12)

This takes the value from the.txt file into the appropriate variable.

```matlab

u1=load('h1.txt')

hueThresholdLow=u1;

```

##  v.2021.1.0.0 

This is an improvement over the previous version, that used guide to generate the gui and the remaining processing functions were executed in a separate .m file.

It took a long time and was out of date.

This method makes use of app designer to create a matlab app, and there is no need for another .m file to process and display the image.
