這里有一些在VisionLab中完成的示例：

捕獲和檢測(cè)移動(dòng)對(duì)象

 

 

捕獲，檢測(cè)并跟蹤目標(biāo)

 

 

在視頻中捕獲和檢測(cè)輪廓和對(duì)象

 

 

VisionLab包含以下組件：

計(jì)算機(jī)視覺：

• 移動(dòng)對(duì)象檢測(cè)組件
• 為邊緣檢測(cè)執(zhí)行Canny算法
• 為邊緣檢測(cè)執(zhí)行自適應(yīng)的閾值算法
• 使用Canny邊緣檢測(cè)和Hough變換查找圖像中的線
• 使用Canny邊緣檢測(cè)和Hough變換查找圖像中可能的線片段
• 使用Hough變換查找圖像中的圓
• 在二進(jìn)制圖像中查找輪廓
• 在圖像中查找可能的目標(biāo)。該目標(biāo)作為strong corner被檢測(cè)到。然后在目標(biāo)會(huì)通過TVLTrackTargets組件被跟蹤
• 在圖像中跟蹤移動(dòng)目標(biāo)。在圖像中該目標(biāo)被作為strong corner跟蹤
• 使用SURF算法提取魯棒特征
• 使用Haar類似的特征檢測(cè)對(duì)象
• 在圖像中編輯連接的組件

Video For Windows(VFW)組件：

• AVI播放器
• 視頻捕獲組件
• AVI記錄器

DirectShow組件：

• DirectShow視頻播放器
• DirectShow視頻捕獲組件
• DirectShow視頻記錄器
• DirectShow圖像顯示
• DirectShow預(yù)覽?？?/li>

本地可視化：
 

• 本地圖像顯示

圖像生成器：

• 從選定的一張圖像（位圖，圖標(biāo)，JPEG等）生成幀。所有的幀都是相同的
• 從Axis網(wǎng)絡(luò)攝像機(jī)捕獲圖像

視頻過濾器;

• 侵蝕或欺騙視頻
• 在視頻上執(zhí)行Wiener過濾器
• 轉(zhuǎn)換該圖像為灰度圖像

幾何變換：

• 更改圖像的尺寸
• 裁剪圖像。只有原始圖像的一部分將出現(xiàn)在輸出圖像中

其他：

在視頻幀上使用（繪制）圖形層

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.
