In a previous entry, we discussed how to preview webcams. In this article, we’ll discuss a Server which saves both video and audio to a file, and streams video over the network. On the other side of the network, we’ll build a small Client to get the video, decode it Read more …
The NVIDIA Jetson TK1 uses Gstreamer as its official multi-media interface. In previous entries we’ve installed two webcams, a Microsoft LifeCam Studio and a Logitech c920. There are several longer range goals with utilizing the webcams, but first up is to show them on the screen. Here’s the video of Read more …
At the IEEE High Performance Extreme Computing Conference (HPEC ’14) in September, Massimiliano Fatica and Everett Phillips from NVIDIA presented a paper Synthetic Aperture Radar imaging on a CUDA-enabled mobile platform. The imaging was done on a Jetson TK1! The abstract: This paper presents the details of a Synthetic Aperture Read more …
The Jetson has a mini PCIe slot, perfect for adding functionality like that provided by the Intel 7260, a 802.11 ac, dual band Wi-Fi plus Bluetooth adapter. I bought the device here: Intel Network 7260.HMWG WiFi Wireless-AC 7260 H/T Dual Band 2×2 AC+Bluetooth HMC, along with a couple of antennas. Read more …
Note: This is for L4T 19.X. For later versions (such as the current 21.X series), please see: Install Grinch Kernel for L4T 21.3 on NVIDIA Jetson TK1 As a young development environment the NVIDIA Jetson TK1 exhibits a lot of promise with lots of raw performance for its form factor Read more …
Researchers in the UK have published a paper “Introducing SLAMBench, a performance and accuracy benchmarking methodology for SLAM” which included the NVIDIA Jetson TK1 in their testing. SLAMBench is a publicly available software framework which provides a KinectFusion implementation in C++, OpenMP, OpenCL and CUDA. Simultaneous localization and mapping (SLAM) Read more …
Back in 2001 Viola and Jones published a paper on a real time face detection framework capable of rapid image processing and high detection rates, one of the seminal works in computer vision. There were three main contributions. First is an image representation called the “Integral Image” which allows features Read more …
The NVIDIA Jetson TK1 has a relatively small main memory for running memory hungry applications like Chromium and compiling large programs. By creating a Swapfile, the Jetson will seem much snappier when a bunch of memory is being consumed. Here’s the video on how to create a Swapfile: You can Read more …
Coming from other computer platforms like Windows and OSX, it seems odd that local disks do not mount automatically on Linux Ubuntu 14.04. This procedure is usually called automount. Sure there’s the distinction between partitions and volumes and all that, but it still seems rather odd to me. Under Linux, Read more …
Back in 1986, John F. Canny developed the Canny Edge detector. I talked about the creation of BitBlt 10 years previous to that, and the Canny Edge was another one of the image processing milestones which is still used today. Here’s the demo of the Canny Edge Detector in OpenCV: Read more …
