VisionLab VC++ 4.0

VisionLab VC++ 4.0 is a group of Visual C++ components for basic computer vision which allows rapid development of fully featured motion detection applications for the security industry with almost zero lines of program code.

It includes Canny edge detection, Adaptive Threshold, Hough Lines, Contour Finder, Target Tracking components. VisionLab also includes video capturing, recording and playback components based on both Video For Windows(VFW), and DirectShow, so no additional components are needed in order to start building computer vision applications.

Major Features:

1. Computer Vision:
   • VLMotionDetect
   • Motion detection component.
   • Performs Canny algorithm for edge detection.
   • Performs Adaptive threshold algorithm for edge detection.
   • Finds lines in the image using Canny edge detection and Hough transform.
   • Finds probable line segments in the image using Canny edge detection and Hough transform.
   • Finds circles in the image using Hough transform.
   • Finds contours in binary image.
   • Finds possible targets in the image. The targets are detected as strong corners in the image. The targets then can be tracked by the TVLTrackTargets component
   • Tracks moving targets on the image. The targets are tracked as strong corners in the image.
   • New: Extracts robust features using SURF algorithm.
   • New: Detects objects by using Haar like features.
2. Video For Windows(VFW) components:
   • VLAVIPlayer
   • AVI Player
   • VLCapture
   • 1Video Capture Component
   • VLAVILogger
   • AVI Logger
3. DirectShow components:
   • DirectShow Video Player
   • DirectShow Video Capture Component
   • DirectShow Video Logger
   • DirectShow image display
   • VLDSVideoPreviewDock
   • DirectShow Preview Dock
4. Native visualization:
   • Native Image Display.
5. Image generators:
   • New: Generates frames from a selected image (Bitmap, Icon, JPEG, etc.). All the frames are identical.
6. Video filters:
   • New: Erodes or deludes the video.
   • New: Performs Wiener filter over the video.
   • New: Converts the image to Gray Scale.
7. Geometric transformations:
   • New: Changes the size of the image.
   • New: Crops the image. Only portion of the original image will appear in the output.
8. Other:
   • VLDraw
   • New: Applies(draws) graphical layers over the video frames.
   • Custom User Filters and Generators
   • New: Generic Video generator
9. The following TimingLab component are included:
   • New: Provides clock for other components.
   • New: Implements a Watch Dog Timer.
   • New: Allows other threads to generate main thread notifications.
10. The following AudioLab components are included as well:
    • New: Generic Audio generator
    • Converts Audio To Real
    • Outputs audio data via audio output device such as Speakers, Line Out, or Modem using Win32 API
    • Outputs audio data via audio output device such as Speakers, Line Out, or Modem using DirectShow
11. The following SignalLab component is included as well
    • Generic Real filter
    • New: Generic Real generator
    • Generic Binary Filter
    • New: Generic Binary generator
