[main]
; camera parameters and high-level algorithm choices
type:	ccd classic
vidext: .DMCdata ; file extension of data
ofmethod: farneback ; farneback param all hard-coded for now.
hssmooth:	10 ; 8 to 50 does well. 100 excessive.
hsiter:     4   ; 1 to 4 is fine, bigger gets slow and doesn't change result much
twoframe:	yes ; indicates it's a method using two consecutive video frames at each time sample interval
addnoise:	no ; this would be for simulations or to test algorithms
; cmin, cmax depend on gain of camera, and are set by human judgement to avoid excessive clipping
; while not wasting dynamic range in scaling from 16-bit data to 8-bit that OpenCV et al can handle.
cmin:   	100 ; minimum 16-bit intensity to clip
cmax:   	46000 ; maximum 16-bit intensity to clip

[filter]
; these parameters are used for preprocessing the video data before morphological operations
wienernhood: 0  ; doesn't seem critical, 0 might be better for farneback to avoid false positive
