Usage: Users can send a POST request to /upload with an image file to upload the image to the server. Then, they can send a GET request to /image/:filename to process the uploaded image. The processed image will be returned as a JPEG file.

Note: Users should make sure to send the correct filename parameter in the GET request to /image/:filename endpoint. Also, users should not rely solely on the deletion of the uploaded image for privacy protection, as downloaded copies of the image may still exist. Additional security measures, such as authentication and access control, should be implemented for enhanced security.
