# Pseudo code for selenoreferencing and image stitching

# Procedure to load CSV file
Procedure load_csv(file_path)
    Return csv_data from file_path

# Procedure to extract longitudes and latitudes from CSV data
Procedure transform_coordinates(csv_data)

# Procedure to resize two images to the same height
Procedure resize_to_same_height(img1, img2)

# Main procedure
Procedure main
    stitched_image, longitudes[], latitudes[] ← stitch_images(image_files, csv_files)
    
    Save stitched_image as "stitched_image.png"
    Save longitudes[] and latitudes[] as "stitched_coordinates.csv"
    Display stitched_image using OpenCV
