Adds a column to the DataFrame with detected objects for each image specified in the 'image_name' column.
Parameters:
df (pd.DataFrame): DataFrame containing a column 'image_name' with image filenames.
image_directory (str): Path to the directory containing images.
detector (ObjectDetector): An instance of the ObjectDetector class.
Returns:
pd.DataFrame: The original DataFrame with an additional column 'detected_objects'.
