OpenVL is the future of developer-friendly computer vision - existing vision frameworks provide access at a very low level, such as individual algorithm names (often named after their inventor), while OpenVL provides a higher-level abstraction to hide the details of sophisticated vision techniques: developers use a task-centred API to supply a description of the problem, and OpenVL interprets the description and provides a solution.

The OpenVL computer vision abstraction will support hardware acceleration and multiple platforms (mobile, cloud, desktop, console), and therefore also allows vendor-specific implementations. We are committed to making it an open API available to everyone (and hope to make it an open standard); Continue reading...

We are very happy to announce the first release of OpenVL! This version provides a high-level interface to image segmentation. Results can be visualised using the included VisionGL library (for testing etc.), or extracted to use for your own applications.

The release contains C++ static library binaries for OS X (Xcode/GCC), Windows (Visual Studio 2010) and Linux (GCC), as well as all the necessary headers, and an example application.

You can download it here: OpenVL-v0.1a-20130701

Please note that this is research software, so expect lots of bugs and missing features. Feedback is appreciated, so please let us know if you find a problem or would like to suggest an addition.

We are also looking for academic and industry collaborations to help develop OpenVL - contact us if you're interested!

We have been invited to speak at the AMD Fusion Developer Summit, 11-14 June 2012 in Bellevue, Washington, U.S.A. We will be presenting OpenVL, our developer abstraction for computer vision: we will cover the central concepts used in our high-level developer interface to computer vision, present examples of the abstraction applied to specific problems such as image segmentation and object detection, and provide a demonstration of the technology in action. If you are planning to attend AFDS, please come and try the demo!

We are pleased to announce our sponsorship of the 1st Workshop on User-Centred Computer Vision (UCCV 2013) will be held as part of the IEEE Winter Vision Meetings in Tampa, Florida, U.S.A. in January 2013. UCCV is a one day workshop intended to provide a forum to discuss the creation of intuitive, interactive and accessible computer vision technologies. The workshop will be focussed on research from academia and industry in the fields of computer vision and human-computer interaction.

The majority of researchers in computer vision focus on advancing the state-of-the-art in algorithms and methods; there is very little focus on how the state-of-the-art can be usefully presented to the majority of people. Research is required to provide new technology to address the shortcomings in the usability of computer vision.

The workshop will bring together researchers from academia and industry in the fields of computer vision and human-computer interaction to discuss the state-of-the-art in HCI for Vision. We invite the submission of original, high quality research papers on user-centred, interactive or accessible computer vision. Areas of interest include (but not limited to):

  • Vision systems/frameworks designed for use by non-experts
  • Visual or Integrated Development Environments for vision system design
  • High-level abstractions of vision algorithms
  • Algorithm/Task/User level API design
  • Detection/tracking/recognition of a physical person as input to an interactive system
  • Interpretation of user input such as descriptions, sketches, images or video
  • Automatic or interactive algorithm selection
  • Automatic or interactive task selection
  • Automatic or interactive parameter tuning for vision algorithms
  • Using computer vision to exploit meaningful user interaction
  • Case studies on user-centred computer vision
  • Interactive/supervised correction of weaknesses in the current state-of-the-art in computer vision
  • Evaluation of vision interfaces (e.g. through user studies)

Through the creation of our computer vision abstraction we have developed a set of guidelines along the way to help steer our design decisions. We believe these guidelines will be of some use to others in the vision community, so will be presenting a few of them at the Human-Computer Interaction workshop held in conjunction with the International Conference on Computer Vision (ICCV) in Barcelona in November.

At the International Conference on Vision Systems this year we will be presenting our latest research into a general abstraction for computer vision, OpenVL. OpenCV and similar systems provide sophisticated computer vision methods directly to the user, which requires a lot of knowledge and experience to use effectively. We have developed a methodology which provides the user with a mechanism to execute the required vision algorithm through a higher level interface, allowing a much larger audience to employ computer vision methods.

As part of the Winter Vision Meetings I am organising the Workshop on Person-Oriented Vision which will be held in Kona, Hawaii on the 5th of January 2011. I intend the workshop to highlight ongoing research in accessible and interactive computer vision, as well as provide an opportunity for discussions on new directions for the field. We are looking to publish work on the following topics:
  • Transforming CV problems to exploit meaningful user interaction
  • High-level abstractions of vision algorithms
  • Automatic or interactive algorithm selection based on user input
  • Detection/tracking/recognition of a physical person as input to an interactive system
  • Interpretation of user input such as descriptions, sketches, images or video
  • Automatic or interactive parameter tuning for vision algorithms
  • Case studies on "Person-Oriented" CV
  • Vision systems designed for use by non-experts
  • Interactive/supervised correction of weaknesses in the current state-of-the-art
The deadline for submissions is the 26th August (abstracts 19th August), using the WACV paper format.

As part of our work to create a Rapid Vision Application Development (RVAD) framework, we are developing an image retrieval abstraction called the Unified Camera Framework. We detail the current system and our initial findings in our paper Uniform Image and Camera Access and will present the work at the Workshop on the Applications of Computer Vision, part of the Winter Vision Meetings, in Snowbird, Utah in December.

Our vision system development framework, VU, provides a new way to organise vision systems and a novel classification of the computer vision problem as a whole. Using our well-defined components for camera access, image conversion and data transport, users can construct vision systems rapidly and easily, to capture and process data. This framework will be presented at the Workshop on Multimedia Information Processing and Retrieval in San Diego in December.

One of the projects we've been working on, called Hive, is a framework for distributed vision processing, allowing reusable modules to be connected together. Modules can be devices such as cameras or algorithms e.g. face tracking. The work will be presented at the International Conference on Distributed Smart Cameras at Stanford University in September.
