So what else can be done with an image matte besides compositing? Because Pixel Feather's software does a great job obtaining a matte with hair or fur you can now do a great job of editing only that region specified by the obtained matte. Once you have obtained a matte, in the same way it is used to delineate transparency through the alpha channel it can be used as a layer mask to restrict image operations to a region of the image in any photo editors that have a layering ability.
The early disklaviers from 1987 through the early 90s recorded Yamaha's e-seq midi files on 3.5" floppy disks. The pianist could record and playback from these disks or with a computer, store, download or share these midi files, as computers at the time all had a floppy drive and a compatible operating system.
To remove the background from any image with Pixel Feather's pullmatte application...

Open an image file with the open file menu, icon or keyboard shortcut CTRL + O
