What can I build with VisionLab?

VisionLab allows rapid development of fully featured computer vision applications for the security industry, scientific and other applications. It also includes Hough Lines, edge detection, contour detection, Haar face and object detection, robust features, and target detecting/tracking components.

 

Applications include:  capture and detect motion, capture and track moving targets in video, detect contours and objects in video, real time data acquisition, process control, artificial intelligence, signal analysis, digital signal analysis, video analysis, data visualization, visual instrumentation and more.

Capture and detect contours and objects in the video:
 
/system/imgs/22/original/ContourDetect.jpg?1311866923
 
 
VisionLab includes a full set of video capturing components. They support the old fashion Win32 API( Video For Windows ( VFW ), WaveAPI, Audio ACM), the newer DirectShow, and even allows if needed any mixture of them. The developer can choose to go with any of them, to use all, or can switch from the one to the other at any moment. The components hide the complexity of all of the approaches, and make them look almost identical from the users prospective.
 
Here is the full list of the supported technologies:
 
Win32 API:
  • Video For Windows ( VFW )
  • Audio Compression Manager ( ACM )
  • WaveAPI
 
DirectX:
  • DirectShow
 
Intel:
  • Intel MMX
  • Intel Performance Primitives ( IPP )
 
The library includes Motion Detection component, Hough Lines and Circles components, Canny and Adaptive Threshold edge detectors, contour detector, Haar face and object detector, target finding and tracking components, robust features component, Video Display, and DirectShow video Render, a Win32 API and DirectShow Video Capture component. Number of additional component from the SignalLab, and from AudioLab are included to allow basic audio processing.

VisionLab: Frequently Asked Questions

Q: Do I have to purchase VisionLab?
A: VisionLab is free for non commercial purposes. This means that you can use it for personal pleasure, hobby, or evaluation purposes. If you are student you can also use it for free for your educational needs including school projects. If you are a tutor at present you also can use it for free for your classes. However in the near future a low cost tutor license will be available, and you will have to purchase it. Your students however will not need license to use the product at class.
Q: Is VisionLab multithreading? Will it stop streaming while I move the window with the mouse?
A: Yes. VisionLab is fully multithreaded and will not stop streaming while the main thread is busy.
Q: Does VisionLab include any video capture components?
A: Yes. VisionLab includes both DirectShow and Video For Windows (VFW) capture components. You don’t need separated capture libraries or components.
Q: Does VisionLab support DirectShow?
A: Yes. VisionLab supports DirectShow 8.1 or higher.
Q: What version of DirectShow I need to run VisionLab?
A: VisionLab supports DirectShow 8.1 or higher.
Q: I want to use VisionLab. Do I have to install DirectShow?
A: DirectShow is not required on your system if you are not planning to write application using the DirectShow components of the package.
