Focalspec Moving Average + Zero Crossing spot detector reference implementation.

The region of interest parameter roi has the following behavior:

• roi = kNULL => full image
• roi != kNULL => roi must point to an array of size >= 4 with {rowStart, rowEnd, colStart, colEnd}
• If any value in (rowStart, rowEnd, colStart, colEnd) is set to kSIZE_NULL, the missing element is mapped rowStart -> 0; rowEnd -> imageHeight; colStart -> 0; colEnd -> imageWidth

Parameters

image	Input image with pixel type k8u
spots	kArrayList of type kFpgaSpot2i
edgeWindow	Size of gradient filter
averageWindow	Size of moving average filter used to determine weather a pixel is inside a spot
intensityWindow	Size of moving average filter used to determine spot intensity
threshold	Threshold against which detection-filtered image is compared to determine if a pixel is inside a spot
edgeImage	Buffer to use for edge image, an internal buffer will be allocated and used if set to kNULL
averageImage	Buffer to use for average image, an internal buffer will be allocated and used if set to kNULL
intensityImage	Buffer to use for intensity image, an internal buffer will be allocated and used if set to kNULL
roi	Region of interest

Returns

kStatus
