这里有一些在VisionLab中完成的示例：

捕获和检测移动对象

 

 

捕获，检测并跟踪目标

 

 

在视频中捕获和检测轮廓和对象

 

 

VisionLab包含以下组件：

计算机视觉：

• 移动对象检测组件
• 为边缘检测执行Canny算法
• 为边缘检测执行自适应的阈值算法
• 使用Canny边缘检测和Hough变换查找图像中的线
• 使用Canny边缘检测和Hough变换查找图像中可能的线片段
• 使用Hough变换查找图像中的圆
• 在二进制图像中查找轮廓
• 在图像中查找可能的目标。该目标作为strong corner被检测到。然后在目标会通过TVLTrackTargets组件被跟踪
• 在图像中跟踪移动目标。在图像中该目标被作为strong corner跟踪
• 使用SURF算法提取鲁棒特征
• 使用Haar类似的特征检测对象
• 在图像中编辑连接的组件

Video For Windows(VFW)组件：

• AVI播放器
• 视频捕获组件
• AVI记录器

DirectShow组件：

• DirectShow视频播放器
• DirectShow视频捕获组件
• DirectShow视频记录器
• DirectShow图像显示
• DirectShow预览停靠

本地可视化：
 

• 本地图像显示

图像生成器：

• 从选定的一张图像（位图，图标，JPEG等）生成帧。所有的帧都是相同的
• 从Axis网络摄像机捕获图像

视频过滤器;

• 侵蚀或欺骗视频
• 在视频上执行Wiener过滤器
• 转换该图像为灰度图像

几何变换：

• 更改图像的尺寸
• 裁剪图像。只有原始图像的一部分将出现在输出图像中

其他：

在视频帧上使用（绘制）图形层

Here are some examples of what can be done with VisionLab:

Capture and detect motion

Capture, detect and track targets

Capture and detect contours and object in the video

The following components are part of VisionLab:

Computer Vision:

• 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.
• Extracts robust features using SURF algorithm.
• Detects objects by using Haar like features.
• Labels connected components in the image.

Video For Windows(VFW) components:

• AVI Player
• Video Capture Component
• AVI Logger

DirectShow components:

• DirectShow Video Player
• DirectShow Video Capture Component
• DirectShow Video Logger
• DirectShow image display
• DirectShow Preview Dock

Native visualization:
 

• Native Image Display.

Image generators:

• Generates frames from a selected image (Bitmap, Icon, JPEG, etc.). All the frames are identical.
• Captures from Axis IP camera

Video filters:

• Erodes or deludes the video.
• Performs Wiener filter over the video.
• Converts the image to Gray Scale.

Geometric transformations:

• Changes the size of the image.
• Crops the image. Only portion of the original image will appear in the output.

Other:

• Applies(draws) graphical layers over the video frames.
