Fast RAW Compression
Recording performance for RAW data acquisition task is essential issue for 3D/4D, VR and Digital Cinema applications. Quite often we need to do realtime recordings to portable SSD and here we face questions about throughput, compression ratio, image quality, recording duration, etc. As soon as we need to store RAW data from a camera, the general approach for raw image encoding is not exactly the same as for color. Here we review several methods to solve that matter.

Low latency H.264 streaming on Jetson TX2
Realtime remote control for any vision system is very important task which has a huge number of applications. People need to control remotely almost everything. To make it possible, we need to create a solution with minimum latency to ensure smooth video and instant feedback. There are a lot of imaging systems which rely on small feedback time, like autonomous cars, hexacopters or drones, mobile robots that should be remotely controlled via wireless network, etc.
GPU software for camera applications
There are many machine vision and industrial cameras with high resolution and high frame rate image sensors. These cameras generate huge amount of data and it's a challenge to cope with them properly. GPU-based image processing is the key to achieve both realtime performance and high quality, especially for multicamera systems.
Jetson zero-copy for embedded applications
Zero-copy means that we don't need to spend any time to copy data from host to device over PCIE, as we always have to do on any discrete laptop/desktop/server GPU. Basically, this is the way of how integrated GPU can take an advantage of DMA, shared memory and caches.
Realtime image processing on GPU for XIMEA CB500
High resolution cameras are getting more and more popular nowadays with resolution parameter ever growing due to advancement in the latest image sensor technology. The newest of them offer remarkable resolution of 50 or more Megapixel pushing the data bandwidth to the edge where it can become a bottleneck.
JPEG2000 vs JPEG vs PNG: What's the Difference?
If you look for a list of image format standards with good compression ratio, a simple Google search will yield a lot of results. JPEG and the similar sounding JPEG2000, along with PNG, are among the best image compression formats today.
Jetson image processing: ISP libargus and Fastvideo SDK
How to build a camera system on Jetson? This is an important task if you want to create realtime solution for mobile imaging application. With a thoughtful design, one can even implement a multicamera system on just a single Jetson, and some NVIDIA partners showcase that this is in fact achievable.
Jetson TX2 and AGX Xavier performance comparison
Imaging applications benefit from the latest NVIDIA mobile GPUs: Jetson TX2 and AGX Xavier. Nevertheless, general benchmarks can't answer the question about performance comparison for the latest NVIDIA Jetson hardware.
