Detailed Description

Temporal Image Averaging Filter.

This filter only averages contiguous frames, unlike add_Filter which allows the use of a stride parameter. The filter will buffer up nFrames worth of images and when enough frames have been buffer, the filter will begin altering the output of the pipeline to be the averaged frames.

Supports the following formats:

• phImageRGB24
• phImageBGR24
• phImageABGR32
• phImageBGRA32
• phImageRGBA32
• phImageGREY8
• phImageHSV24

Todo:

merge with the other temporal filters

add example application code that shows how the processed images were output

Todo:

add example image inputs and processed image outputs
