OpenCV Color Segmentation and Tracking on DragonBoard 820c

Posted by Charbax – October 5, 2018

This demo is based and tested on the DragonBoard 820c, but should be able to work on varying platforms. In summary, it counts objects by color passing in the same direction through the camera field of view. It can count multiple objects simultaneously. The OpenCV functionality leveraged by this demo includes the following:

- Object segmentation using color
- Valid object identification by size
- Frame stitching to track and count multiple simultaneous moving objects by color
- Provides hooks to monitor performance when algorithm changes to - - OpenCV library calls are made for identification tuning
- Provides hooks to export results to the cloud

Standardizing software support for 96Boards with Mani

Posted by Charbax – September 26, 2018

Mani is an Applications Engineer at 96Boards team of Linaro. He works on improving the user experience with 96Boards by upstreaming it's stadardized software support. He goes over the journey of how he started with 96Boards, what his initial responsibilities were and how it has been evolved over time. He also explains his recent work towards standardizing the software support for 96Boards and stresses the importance of having a unified software layout across all 96Boards of same category. In this video, he mentions his latest work towards standardizing the LED labels/triggers in Linux kernel and how that impacts the user experience on userspace library such as MRAA (https://github.com/intel-iot-devkit/mraa).

MRAA library with Mani of 96Boards

Posted by Charbax – September 26, 2018

MRAA (https://github.com/intel-iot-devkit/mraa) is a low level skeleton library for Linux based systems which provides userspace access to the peripherals on 96Boards Consumer Edition boards using multiple interfaces such as C, C++, Python, Java and Javascript. Mani, being the Co-Maintainer of this library, talks about the history of how 96Boards started using this library instead of their legacy 96BoardsGPIO library. Also, he explains how the MRAA library serves well for them to handle multiple 96Boards with different SoCs which no other platform is doing.

Open Source Academics (OSA) by 96Boards with Robert Wolff

Posted by Charbax – September 26, 2018

Open Source Academics (OSA) by 96Boards (https://github.com/osacademics) aims to facilitate and expand the educational experience on a global stage by providing scalable curriculum and standardized course materials through an open source platform. To fully understand the diverse nature of OSA, this summary will be broken down into seven discrete sections: Motivation, Mission, Platform, Stakeholders, Infinity Committee, Incentives and Roadmap.

OSA wants to unite industry and academia to create, and host a fully functional and open sourced educational platform which facilitates consumption and contribution of standardized educational curriculum and incentivized course materials on a global scale (with a current focus on STEAM content). OSA will work with stakeholders to achieve a balanced set of standards and incentives which encourage collaboration and drive content quality and growth.

Fujitsu A64FX Post-K Supercomputer: World’s Fastest Arm Processor

Posted by Charbax – September 24, 2018

Fujitsu A64FX is the new fastest Arm processor in the world, built on 7nm it has 2.7 TFLOPS performance per chip suitable for high-end HPC and AI, they aim to create with it the world's fastest supercomputer with it by 2021. A64FX is the first processor using the new Armv8-A Scalable Vector Extension (SVE) to accelerate a wide range of large-scale scientific computing, including deep learning. Fujitsu is working closely with Linaro to enrich the Arm HPC ecosystem. A64FX will be featured in the post-K computer, a supercomputer being developed by Fujitsu and RIKEN as a successor to the K computer, which achieved the world's highest performance in 2011. The organizations are striving to achieve post-K application execution performance up to 100 times that of the K computer. It offers a number of features, including broad utility supporting a wide range of applications, massive parallelization through the Tofu interconnect, low power consumption, and mainframe-class reliability.
