Query: Image Handling and Processing for Efficient Parking Space Detection and
  Navigation Aid   This paper aims to develop a robust and flexible algorithm for vacant parking
space detections using the image processing capabilities of OpenCV. It removes
the need for independent sensors to detect a car and instead, uses real-time
images derived from various sources and servers to consider a group of slots
together. This greatly decreases the expenses required to design an efficient
parking system and increases the flexibility of the operation. This method
includes the use of a portable processing system with recognition algorithm and
has the option of extracting and importing images to the specified servers. The
results can be viewed on a custom website with the option to reserve the
particular empty slots and GPS navigations to the selected slots.
