Live image capture in Color Thresholder app
You can now do color thresholding on an image acquired from a Webcam using the Color
Thresholder app. The new Image Capture tab allows you to bring a live image from USB
Webcams into the app. Previously, you had to save your images to disk and manually add
them into the app.
The image capture functionality in the Color Thresholder app allows you to:
• Capture live images from USB Webcams
• Save an acquired image to a variable
• Integrate between image acquisition and color thresholding
• Control camera properties, such as brightness and contrast
Use the colorThresholder function to open the app. Then select Load Image >
Acquire Image From Camera to open the Image Capture tab. Select your device, set
any properties, and preview the image. You can then capture an image.
