Filters is a simple implementation of some of instagram filters like grayscale, sepia using C and Bitmap to dealing with photo as an array of pixels.
You need to have C installed on your machine, and GCC Compiler.
First you need to compile the program, so head to the path that you saved the project in and type
gcc filter.c [-filter] [PathOfInputImage].bmp [out].bmp
then you will notice an output file with the name you specified [out].bmp has been created in the folder, it's the image after the filter applied to it.
Here's the type of filters provided:
"b" => for the blur
"g" => for the grayscale.
"r" => for reflect (mirror).
"s" => for sepia.
