ok, this is very simple..

But nice..!

Place your webcam so, that is is looking to the other side of your room or some place were people walk by.

run the script. the point where the mouse is, is were it is going to get a color from.

What this script simply does is get a color from a point and then if the color changes it plays a beep song and it adds $found + 1

so here it is:

WebcamSpy.au3

Have fuN!

and look at my sig or download here:

Webcam.au3

I like. I dont have a camera here to test with, but plan on checking it out when I get home. I'd also like to modify it so I choose a region instead of hardcoded region.

See my last post for my latest version

Ok, It's still not elegant, but here's my second attempt at modifying/enhancing this script. Suggestions/feedback welcome. Requires the webcam UDf in ludocus' first post.

edit: added screen capture for trigger event and set region reset if window moves. Changed beep to random sequence. Sounds like r2d2.

Sloppy code, sorry. Woo Hoo. 300th post.

Yikes yikes yikes! super buggy. I need to work on my math. I am ashamed for posting such buggy crud. I'll repost when I get the kinks out.

edit: The new and improved version. Supports multiple detect regions. ;) I commented out the screencapture feature so if you want it to do screenshots, uncomment line 98.

New and improved version above. ;) Multi-region support

Thanks a bunch to ludocus for giving me (and the comunity) the building blocks for this webcam stuff.

edit: I added color correction for lighting changes over time. Also limits trigger to 5 seconds apart minimum and also does color correction.

Alright, this'll be my last post on this topic. The latest and greatest version.

Changes include: Multiple Trigger events. Window adjustment calculation (window gets moved) Added crummy region highlighter when setting/selecting a region. Enjoy.

edit: fixed a fews bugs. Last version.

Warning! The video capture length is unpredictable. Don't leave unattanded - Potential HD Filler!

Here's a function to compare two colors. Use it to eliminate false positives.

Func _ColorInBounds($pMColor, $pTColor, $pVariation)
    $lMCBlue = _ColorGetBlue($pMColor)
    $lMCGreen = _ColorGetGreen($pMColor)
    $lMCRed = _ColorGetRed($pMColor)
    
    $lTCBlue = _ColorGetBlue($pTColor)
    $lTCGreen = _ColorGetGreen($pTColor)
    $lTCRed = _ColorGetRed($pTColor)
    
    $a = Abs($lMCBlue - $lTCBlue)
    $b = Abs($lMCGreen - $lTCGreen)
    $c = Abs($lMCRed - $lTCRed)
    
    If ( ( $a < $pVariation ) AND ( $b < $pVariation ) AND ( $c < $pVariation ) ) Then
        Return 1
    Else
        Return 0
    EndIf
EndFunc

_ColorGetX functions are defined in either Color.au3 or Misc.au3

I could if it was properly coded, instead of using Globals for everything..

Func _ColorInBounds($pMColor, $pTColor, $pVariation)

$pMColor = 0xFFFFFF

$pTColor = 0x000000

$pVaration = 25

;; With these paremeters it will return false.

$pMColor = 0xFFFFFF

$pTColor = 0xEEEEEE

$pVaration = 25

;; With these paremeters it will return true because the colors are close together.
