IMAGE_PROCESSING_APP

A desktop application written in java for processing grayscale images.

Features :

Read / Write PPM and PGM file format
Calculating image metrics such as : mean and standard deviation
Drawing the grey level histogram , the cumulative histogram
Histogram equalization
Linear transformation
Adding salt and paper noise
Applying Filters : median filter ,mean filter , outline filter
PPM images segmentation using thresholds
Using Otsu segmentation algorithm with opencv

Objectives learnt :

Learning the fundamental concepts of image processing
Developping some of the PPM images functionalities ( read , write , calculating metrics , applying filters , performing linear transformation )
Using javafx for the GUI
Integrating opencv library to calculate otsu threshold , to erode and dilate images

Demo :

1- Applying median filter to a noisy image (salt and paper noise )

`Noisy image`

`Filtered image`

2- Applying high-pass filter (and outline filter)

`Original image`

`Filtered image`

3- Image after Histogram equalization

`Original image`

`Adjusted image`

4- Linear Transformation :

5- Segmentation using Otsu :

`Original image`

`After segmentation`

6-Erosion (Kernel size is 5*5 , kernel types : rectangle , cross , ellipse ) :

7-Dilatation (Kernel size is 5*5 , kernel types : rectangle , cross , ellipse ) :
