Image Filtering with Convolution

Description

This C/C++ program reads in raw format images and performs filtering by convolving them with small operators of 3×3 and 5×5 coefficients. The program applies differentiation by difference using edge operators such as the Sobel Operator in x and y directions. It computes horizontal and vertical differential images separately and saves them for display.

Input Images

1. Circle Image: Created using Photoshop with a dark intensity circle inside it.
2. Unesco-1.png: Provided in the file page of CANVAS.
3. Custom Image: Any small-sized image selected by the user.

Output Images

The resulting images are saved in raw format and converted to jpg/png format as well. The output images include:

1. Horizontal and vertical difference images for 3×3 filter size.
2. Horizontal and vertical difference images for 5×5 filter size.

Program Details

The program applies convolution with 3×3 and 5×5 filters to perform image filtering. It then normalizes the filtered results to prevent overflow.

Usage

1. Compile the program.
2. Execute the compiled binary.
3. Input the file paths for the raw format images.
4. Check the output images generated in the specified directory.

Repository Contents

1. Source Code: Main.cpp
2. Input Images: Circle.raw, Unesco-1.png, CustomImage.raw
3. Output Images: (To be generated by running the program)
