SmoothImage_Gauss_Mask


Smooths an image using a predefined gaussian kernel.

Name Type Description
inImage Image Input image
inRoi Region* Range of outImage pixels to be computed
inKernel GaussKernel Predefined Gauss kernel
outImage Image Output image

Applications

Removal of gaussian noise from images (fast).

Description

This operation is a simplified, fast in computation, version of SmoothImage_Gauss, with predefined kernel and simplified ROI handling.

Kernel used in operation can be chosen by inKernel parameter:

  • Box_3x3: 3 by 3 pixels kernel with StdDev ≈ 0.85 of following form:
  • Box_5x5: 5 by 5 pixels kernel with StdDev ≈ 1.1 of following form:
  • Box_7x7: 7 by 7 pixels kernel with StdDev ≈ 1.7 of following form:
  • Box_9x9: 9 by 9 pixels kernel with StdDev ≈ 2.0 of following form:
  • Box_11x11: 11 by 11 pixels kernel with StdDev ≈ 2.2 of following form:

Hints

  • Select kernel size by setting the inKernel input.

Examples

SmoothImage_Gauss_Mask performed on a sample image with inKernel = _11x11.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT16.

This operation supports automatic parallelization for multicore and multiprocessor systems.

Complexity Level

This filter is available on Basic Complexity Level.
