Research direction

Review the existing filter implementation structure in the jimp source code, particularly looking at how other morphological operations or filters are implemented in the src/ directory. The issue references OpenCV's documentation for erosion and dilation; use that as a guide to implement the algorithms. Ensure to add corresponding tests in the test/ directory and update the documentation if needed.
