Median Filter Project

Introduction

This project implements a median filter for image processing using C# (Windows Forms Application). The filter is applied to an image, and the implementation utilizes two external dynamic-link libraries (DLLs) written in C++ and x64 assembly. The project allows configuring the number of threads used for parallel processing.

Prerequisites

Ensure you have the following installed before running the project:

• Visual Studio (for C# development)
• C++ compiler (for compiling C++ DLL)
• Assembler (for assembling x64 assembly code)

Project Structure

The project consists of the following components:

C# Code (Fijalkowskim_MedianFilter)

• DataManager: Manages the image data, filtering, and threading.
• DllType: Enum specifying the type of DLL to use (CPP or ASM).
• Controller: Connects data managment with user interface.
• Other helper classes and methods.

C++ DLL (JACpp.dll)

• Provides a C++ implementation of the median filter.

Assembly x64 DLL (JAAsm.dll)

• Provides an x64 assembly implementation of the median filter.

DLLs

The project uses two DLLs written in C++ and x64 assembly to perform the median filter. The DLLs should be compiled separately using the provided source code.

Usage

1. Open the solution in Visual Studio.
2. Build the solution to compile the C# code.
3. Compile the C++ DLL (JACpp.dll) and the x64 assembly DLL (JAAsm.dll) separately.
4. Ensure that the DLLs are in the appropriate debug/release folders.
5. Run the application.
