Pixel Quantification - v1.0,  © 2004 Richard Rosenman Advertising & Design. Release date: 04/30/05, Updated --/--/--.


INSTALLATION:

Simply unzip "quantification.zip" and copy "quantification.8bf" to your "\Photoshop\Plug-Ins\" folder, or whichever plugin folder your host program uses. Load your program, open an image, go to the plugins menu and select the plugin.


DESCRIPTION:

This filter calculates the sum of a selected number of pixels above a level threshold. It has been primarily developed for biological protein strand analysis although it is suitable for various other uses. Thanks to David Ng for conceptualization.

The filter will automatically invert the image - a special requirement.

1 - First left-click in the preview window on a dark area to specify the selection marquee for the background (BG) level.

2 - Change your Marquee width and height if needed.

3 - Click 'Derive BG Level' to calculate the average pixel level of the selected pixels. This will set the 'BG Level' slider to the derived value.

4 - Left-click in the preview window again to specify your new selection. You can drag the image by right-clicking.

5 - Click 'Quantitate > BG' to calculate the total sum of the levels of all pixels within the selection marquee greater than the 'BG level' threshold.

Info: Displays relevant information about the image and filter operation.

Realtime Preview Update (Pushbutton): Applies all effects (in realtime) on 'mouse drag' instead of on 'mouse release'.

Help:  Displays this help.\nReset: Resets all controllers to default settings.
