Image Filtering and Convolution Process

✨Simple image processing ✨

Project Achievements

• Simple to intermediate pointer use
• Write a module that holds methods together
• Getting information about the PGM file content
• Basic image processing
• Learning gray-level tones

As seen in the picture above, a different type of filtering is applied according to the values ​​of each kernal matrix to filter the picture with a kernel filter matrix.

In this project, the picture with batman and joker was chosen as the picture to be filtered. But when using this image in the project, we need to use it in pgm format.

Tech

• C programing Language

You can access my project about creating visual images with Julia set here.

Installation

This requires TDM-GCC 4.9.2 4.9.2 to run.

If you want to filter the image you want, in the pgmimage.h file:

 void readPGMFormattedImage(PGMFormattedImage *pgmFormattedImagePointer ){
  ...
  if( ( pgmFILE = fopen( "./Batman_2048.pgm", "r" ) ) != NULL ) // pgm file path
  ...
  
 void writePGMFormattedImage( PGMFormattedImage* pgmFormattedImagePointer ){
 ...
 if( ( pgmFILE = fopen( "./Processed_Batman_2046.pgm", "w" ) ) != NULL ) // pgm file path
 ...

}
} 

You should change the file path in the line.
