A possible approach to mitigate this problem consists in reducing the amount of data to transmit to ground through on-board processing of hyperspectral images. In this paper, we propose a custom Convolutional Neural Network (CNN) deployed for a nanosatellite payload to select images eligible for transmission to ground, called CloudScout. The latter is installed on the Hyperscout-2, in the frame of the Phisat-1 ESA mission, which exploits a hyperspectral camera to classify cloud-covered images and clear ones. The images transmitted to ground are those that present less than 70% of cloudiness in a frame. We train and test the network against an extracted dataset from the Sentinel-2 mission, which was appropriately pre-processed to emulate the Hyperscout-2 hyperspectral sensor.

  • Benchmarking of Cnns for Low-Cost, Low-Power Robotics Applications
    Benchmarking of CNNs for Low-Cost, Low-Power Robotics Applications Dexmont Pena, Andrew Forembski, Xiaofan Xu, David Moloney Abstract—This article presents the first known benchmark of Convolutional Neural Networks (CNN) with a focus on inference time and power consumption. This benchmark is important for low-cost and low-power robots running on batteries where it is required to obtain good performance at the minimal power consumption. The CNN are benchmarked either on a Raspberry Pi, Intel Joule 570X or on a USB Neural Compute Stick (NCS) based on the Movidius MA2450 Vision Processing Unit (VPU). Inference performance is evaluated for TensorFlow and Caffe running either natively on Raspberry Pi or Intel Joule and compared against hardware acceleration obtained by using the NCS. The use of the NCS demonstrates up to 4x faster inference time for some of the networks while keeping a reduced power Fig. 1: Embedded environments used to evaluate the inference consumption. For robotics applications this translates into lower time and power consumption of the CNNs.

  • Intel Vision Products
    INTEL IS ACCELERATING COMPUTER VISION AI Solutions for Any Business, in Any Industry The Evolving Landscape of Artificial Intelligence in Business Our world is changing. And with it, so too is the way we think about the capabilities of the Internet of Things. What began as a conversation about connecting the unconnected has turned into a larger conversation about data—how connected devices can capture it and how businesses can analyze it to make better, faster decisions. It’s not surprising, then, that this emphasis on the importance of data has resulted in technology that has evolved to usher in an era of AI that is not only changing the way we interact with one another, but also the way that companies interact with us. In order to provide the market with the most innovative products and software possible, businesses today require solutions that help them react quickly to the needs of their customers. While traditionally the primary use cases for artificial intelligence have been solely in data centers, where applications have been focused on better managing infrastructure or on monitoring, analyzing, and eventually improving enterprise operations, AI is no longer so limited. Instead, with Intel® Vision Products, a portfolio of acceleration tools designed specifically for AI at the edge, businesses can take advantage of near real-time information to help them make better decisions in a timely manner.
