Adding Machine Learning based Image Processing to your Embedded Product

Convert model tensorflow runtime to NNEF

CNXSoft: This is a guest post by Greg Lytle, V.P. Engineering, Au-Zone Technologies. Au-Zone Technologies is part of the Toradex Partner Network. Object detection and classification on a low-power Arm SoC Machine learning techniques have proven to be very effective for a wide range of image processing and classification tasks. While many embedded IoT systems deployed to date have leveraged connected cloud-based resources for machine learning, there is a growing trend to implement this processing at the edge. Selecting the appropriate system components and tools to implement this image processing at the edge lowers the effort, time, and risk of these designs. This is illustrated with an example implementation that detects and classifies different pasta types on a moving conveyor belt. Example Use Case For this example, we will consider the problem of detecting and classifying different objects on a conveyor belt. We have selected commercial pasta as an example […]

ARCO is a Real Robot that Lives in Virtual Worlds (Crowdfunding)

Hicat launched HICAT.Livera machine vision board for robotics projects on Kickstarter two year ago. The company second project is still related to robotics and machine vision, but geared towards a different target audience, as ARCO robot aims to offer an augmented reality gaming experience to kids, although it’s still hackable/customizable as we’ll see below. The hardware part is mostly comprised of ARCO ROVER robot, and a Bluetooth controller that can be stored in ARCO’s inner capsule, where it recharges and communicates with ARCO through a magnetic pogo connection joint.
