Traveling matte extraction system
First Claim
1. A traveling matte process comprising the steps of:
- converting a first picture including a foreground and background image an electronic form such that said first picture can be stored in a computer;
storing said first picture in said computer;
converting a second picture including only said background image, to said electronic form;
storing said second picture into said computer;
subtracting one picture from the other picture using said computer to arrive at a difference image;
changing the shade of the difference image to a uniform black shade creating an electronic male matte having only black and white regions;
storing said electronic male matte;
changing the black shade values of said male matte to white values and changing the white shade values of said male matte to black values thus creating an electronic female matte; and
converting said male and female matte from said electronic form to a photographic material such as film.

Abstract
A process for producing a traveling matte by first converting a first picture including a foreground and a background image to an electronic form into computer memory. Then, converting a second background picture to electronic form and storing it into computer memory. The computer is then used to subtract one stored picture from the other to arrive at a difference image. The shade of the difference image is then changed to a uniform black color, thereby creating an electronic male matte having only black and white regions, which is stored in the computer memory. The computer is then used to change all black regions of the male matte to white regions and all white regions of the male matte to black regions, thereby creating a female matte, which is stored in computer memory. Finally, the stored male and female mattes are converted from electronic form to a photographic material, such as film.

9. A traveling matte process comprising the steps of:
-
recording a first picture including a foreground and background image; recording a second picture including said background image; subtracting said second picture from said first picture such that said background image is deleted and said foreground image remains; changing the opacity of said foreground image thereby creating a uniformly opaque male matte; storing said male matte; using said male matte to create a contrasting female matte; and storing said female matte.
