     Applies Gaussian blur to an image and saves the output.
-
     This function reads an image, applies a Gaussian blur with the given 
     kernel size and sigma, and saves the processed image to the output path.
 
     Args:
-        image_path (str): The file path of the input image.
-        output_path (str): The file path where the blurred image will be saved.
-        kernel_size (int): The size of the Gaussian blur kernel (must be an odd number).
-        sigma (int): The standard deviation for the Gaussian kernel.
-
-    Returns:
-        str: The path to the saved blurred image.
+        image_path: The file path of the input image.
+        output_path: The file path where the blurred image will be saved.
+        kernel_size: The size of the Gaussian blur kernel (must be an odd number).
+        sigma: The standard deviation for the Gaussian kernel.
