This is what you are looking for with regards on how to create a mask using the extract method:
http://www.russellbrown.com/tips_tech.html
Click on the Advanced Background Extraction quicktime file or Advanced Masking, and here are the transcribed steps to the step by step video:
EXTRACTION
- Draw path around object with either pen tool or the polygonal lasso tool.
- Select Paths Palette -> at bottom of palette, select create path from selection.
- Select Channels Palette -> Create new channel
- On the new alpha channel, CTRL + I to invert the alpha channel.
- Use a paintbrush to stroke the path. Select the paint brush size (4pt); Mode – Normal; Hardness – 96%; click enter or select the stroke path with brush at bottom of Paths Palette (this step softens the edge with a little bit of anti-aliasing)
- Select Layers palette; verify a background copy exists; and select it
- Filter -> Extract -> select Alpha channel 1 that was made
- Add areas of contrast around the edge, then select Fill to fill the image that you want to keep
- Select the newly create invisible transparent mask by selecting the layer and clicking the control key (CTRL click on newly extracted image)
- Turn on original image (Background), turn off the background copy
- Duplicate background copy one more time
- With the new background layer directly under the newly extracted image and with the new background layer selected, Select->ADD VECTOR MASK at bottom of palette
- Clean up new mask by painting with black – areas that were not defined well by the extraction
- To adjust the mask globally, target the mask by clicking on it and then bring up the levels control
- Turn on mask with alt click to see it with levels
- Target the mask and select the BLUR tool (not blurring the image, but blurring the mask)
