Working with CUDA on the Jetson Xavier

A lot of CUDA samples are included , one of these samples is imageDenoising. This sample demonstrates two adaptive image denoising techniques: KNN and NLM, based on computation of both geometric and color distance between texel



Check out the samples included with CUDA and what they do in CUDA Samples.

If you are new to the Xavier or are planning on getting one please visit our Jetson Xavier wiki page.

Tuning Jetson Xavier's Performance

The JetPack provides the tegrastats utility program which reports memory, processor and gpu usage, power consumption and temperature for Tegra-based devices.




The JetPack also provides with a command line tool called nvpmodel which can modify the performance for a given power budget. It provides power budgets for 10W, 15W, 30W and a no-budget mode for max performance. This will modify number of CPUs online, maximum frequency for CPU, GPU, DLA, PVA and number of online PVA cores. Values set by nvpmodel will persist across power cycles.


Finally the jetson_clocks.sh script provides the best performance for the current nvpmodel by setting the clock frequencies to the max frequency and disabling dynamic frequency scaling.


For examples on how to use this utilities please visit performance tuning wiki page.

RidgeRun - GStreamer Deep Learning inference plugin: GstInference

GstInference is an open-source project from RidgeRun Engineering that provides a framework for integrating deep learning inference into GStreamer.

Check out the presentation from RidgeRun Engineering team about our latest development on GstInference at Edinburg GStreamer Conference 2018.

Deploying Deep Learning on the Jetson Xavier using the Deep Learning Accelerator

jetson-inference is a training guide for inference and deep learning on Jetson platforms. It uses NVIDIA TensorRT for efficiently deploying neural networks.The "dev" branch on the repository is specifically oriented for Jetson Xavier since it uses the Deep Learning Accelerator (DLA) integration with TensorRT 5.


With jetson-inference you can deploy deep learning examples on the Xavier in a matter of minutes. Some of the example applications are showed below.


ImageNet is a classification network trained with a database of 1000 objects. The input is an image and it outputs the most likely class and the probability that the image belongs to that class.



Image recognition networks output a class probabilities corresponding to the entire input image. Detection networks, on the other hand, find where in the image those objects are located. DetectNet accepts an input image, and outputs the class and coordinates of the detected bounding boxes.



For more examples and a tutorial on how to get jetson-inference running in your Xavier please visit our jetson-inference wiki page.

Object tracking in Jetson TX1/TX2 using GStPTZR

RidgeRun's new GStPTZR element allows to crop, zoom and rotate a video stream, simulating the behavior of a pan/tilt/zoom/rotate PTZR video camera.

These features, paired with information obtained from a jetson-inference pre-built model, can be used to provide a video stream focused on the detected object.

Captured video (left) is provided to a jetson-inferencce model. The model detects a person and provides the location. GstPTZR is used to crop the area of interest as a separate stream.
Using the GstPTZR element in an already-existing GStreamer pipeline is easy, and can provide a simple way to focus on the important parts of the video stream. 

Captured video (left) and the cropped version obtained with GStPTZR (right) that allow for detection of an object on a specific area of the video.
RidgeRun's GStPTZR is highly customizable and can be used for a wide variety of applications, both paired with detection models and other specific use cases.

For more information, visit www.ridgerun.com/gstptzr and contact us at support@ridgerun.com to request an evaluation version for your application.

The examples in the pictures above were created using models from the Jetson Inference guide.
