[M4IF Technotes] Mask pics (binary or shape images) problem

[BianSH]

I have a question about the Masks for MPEG-4 video sequences on M4IF's resource page.
I download all .seg.zip files and unzip them, but i don't realize how to use the .seg files.
How can I  get the mask sequences (ex:bmp files)  from the "seg" file?
On the other hand, i wonder that where we can obtain the mask pics in Internet to test our research?
Grateful to you for your answers!
