Aerial Object Tracking on CUDA with CUVI Unmanned aerial vehicles or UAVs with a real-time video feed offer numerous vision applications ranging from civil to military use cases. Many of these applications depend on detection of objects and tracking those objects along the scenes. The feedback from tracking data can also be used to automatically steer UAVs to follow that object or person of interest. In this article we’ll use code example to show how this can be done using CUVI. We will use the following video feed captured via a UAV, courtesy of IVUL lab at kaust . The above video is captured at a resolution of 1280×720 at 24fps and is increased to 30fps for viewing purpose. In this example, we will track the black SUV across the feed using CUVI’s goodFeaturesToTrack and trackFeatures functionality.

Our journey began in early 2010 when we envisioned a library built on top of CUDA to provide accelerated primitives for vision applications. Since then we have helped dozens of companies and thousands of users with their performance needs. Today, we are better, faster and more robust than ever. We thank NVIDIA to recognize our efforts by giving us the appreciation that our developers deserve.

The quality and even more so the speed at which a vision library can perform various types of rotation is vital to some industries. For example the rate at which a scanner can churn pages impacts greatly on its sales. That’s why Scantron , a global leader in scanning, uses CUVI for their line of products to self-align scanned documents at an insanely fast rate. Image rotation can be of two broad types: cropping and non-cropping. Most image editing software uses cropping-based rotation (along with zoom) for image straighten purposes. Industries and data sensitive application, on the other hand, use non-cropping rotation.

To run CUVI on your machine, you’ll need an entry level understanding of C++ and NVIDIA GPU in your system. CUVI requires no or very little knowledge of programming skills yet provides sophisticated computer vision features ranging from medical, security, camera and research domains. Use CUVI to start building complex vision applications today! Recently we have release version 1.6.0 which is available for download for free (for personal use) with nearly one hundred features including image filtering, transforms, geometric, color operations and computer vision. For any help and assistance, drop us an email at contact[at]cuvilib.com. In this article, I’ll be talking about some of the most sought-after features of CUVI. But first let’s go through how easy it is to use.

According to the release notes, 10.2 will be the last version of the toolkit to support mac operating system while the next release will remove the support.

CUVI and NPP both have been in market for almost a decade now. NVIDIA’s own performance primitive library (NPP), which started as a CUDA-alternative to IPP , now has hundreds of functions over its decade long releases. These functions provide a quick way to prototype applications on massively parallel GPUs without much of a learning curve. CUVI (CUda Vision and Imaging) SDK, on the other hand, with its limited functionality, provides the most cutting edge computer vision solutions and offers production quality verticals for various domains. In this post, I will be comparing one of CUVI’s most popular feature; debayer with its counterpart in NPP. It’s fair to mention that NPP’s debayer offers only bi-linear approach:Missing pixel colors are generated using bi-linear interpolation with chroma correlation of generated green values . This is the most basic approach to regenerate a colored image from CFA and is prone to artifacts at high feature regions. For a much better regeneration, CUVI offers the newer, much improved DFPD approach to debayering.

Today, I’m going to reveal what it does to underwater videos – most of which are shot using GoPro. You’ll find link to each of the original video to better compare the effectiveness of the filter: GoPro on Hammerhead Fin Original Video Link Continue reading Testing Underwater Video Enhancer on Real Videos” Posted in CUVI Tagged cat , enhance , filter , gopro , shipwreck , underwater , video Leave a Comment on Testing Underwater Video Enhancer on Real VideosCUVI’s Underwater Filter in Action This page is a showcase of our new underwater filter that removes haze and brings out the real colors to your underwater photography. All the results are generated from ‘Auto’ setting of the filter. Although Auto mode works on most of the images like magic, the filter is heavily parameter-ized to fine tune the results. Apart from removing haze, it also enhances the colors of haze-less images and is so addicve that you start using it on every underwater photo by default. Feel free to comment your thoughts below and contact us if you’re interested in purchasing this feature.
