Use the Filter VIs to filter your images to enhance the information in the image. Use these VIs to smooth your image, remove noise, and find edges in the image.
| Palette Object | Description |
|---|---|
| IMAQ FPGA Convolute |
Filters an image using a linear filter. |
| IMAQ FPGA LowPass |
Calculates the inter-pixel variation between the pixel being processed and those pixels surrounding it. If the pixel being processed has a variation greater than a specified percentage, it is set to the average pixel value as calculated from the neighboring pixels. Refer to the NI Vision Concepts Help for more information about lowpass filters. |
| IMAQ FPGA NthOrder |
Orders, or classifies, the pixel values surrounding the pixel being processed. The data is placed into an array and the pixel being processed is set to the nth pixel value, the nth pixel being the ordered number. Refer to the NI Vision Concepts Help for more information about the Nth order filter. |
| IMAQ FPGA Edge Detection |
Extracts the contours (detects edges) in gray-level values. Refer to the NI Vision Concepts Help for more information about edge-detection filters. |
