SPEED: Separable Pyramidal Pooling EncodEr-Decoder for Real-Time Monocular Depth Estimation on Low-Resource Settings

Speed is a critical factor in many computer vision tasks, such as scene understanding and visual odometry, which are essential components in autonomous and robotic systems. The ability to estimate depth from a single frame is called monocular depth estimation (MDE), and it is an essential skill for many computer vision applications. However, vision transformer architectures are too deep and complex for real-time inference on low-resource platforms. This is where the Separable Pyramidal pooling EncodEr-Decoder architecture comes in.

What is SPEED?

SPEED is a fast-throughput deep architecture designed to achieve real-time frequency performances on multiple hardware platforms. It is specifically designed for MDE and operates on edge devices with minimum hardware resources. The encoder-decoder model exploits two depthwise separable pyramidal pooling layers, which increase the inference frequency while reducing the overall computational complexity of the system. SPEED is the first MDE model that can achieve real-time performance on low-resource platforms such as cloud CPU, TPU, and the NVIDIA Jetson TX1.

What are the benefits of SPEED?

The primary advantage of SPEED is its ability to achieve real-time frequency performance on low-resource platforms. This is particularly important for autonomous and robotic systems that need to make critical decisions in real-time. The use of separable pyramidal pooling layers allows SPEED to achieve high accuracy depth estimations from low-resolution images using minimum hardware resources. This makes it an ideal solution for indoor navigation and surveillance systems, where resources are limited, and real-time performance is critical.

Another advantage of SPEED is that it performs better than other fast-throughput architectures in terms of both accuracy and frame rates. Its superior performance is the result of its encoder-decoder model, which allows it to take advantage of the latest advancements in computer vision technology.

What are some potential use cases for SPEED?

There are many potential use cases for SPEED in the field of computer vision. Some potential applications include:

  • Autonomous vehicles: SPEED could help autonomous vehicles better understand their surroundings in real-time, making them safer and more efficient.
  • Surveillance systems: SPEED could be used in surveillance systems to quickly and accurately detect objects and people in real-time.
  • Indoor navigation: SPEED could help robots and other autonomous systems navigate indoor environments with accuracy and speed.
  • Virtual reality: SPEED could be used in virtual reality applications to provide more accurate and realistic depth perception.

What is the future of SPEED?

SPEED is just the first step in creating fast-throughput MDE architectures that can operate on low-resource platforms. As the field of computer vision continues to advance, we can expect to see even more sophisticated models that are better suited for real-time performance on edge devices. However, SPEED represents a significant leap forward in this area and will likely serve as a foundation for future models in the years to come.

In summary, SPEED is a fast-throughput deep architecture designed to achieve real-time frequency performance on multiple hardware platforms. Its ability to accurately estimate depth from low-resolution images using minimum hardware resources makes it an ideal solution for a wide range of computer vision applications, including autonomous vehicles, surveillance systems, and indoor navigation. Its superior performance and the use of separable pyramidal pooling layers make SPEED a critical tool for any developer working in the field of computer vision.
