Image Formats Understood by the Face Detector
A number of image file formats are understood by the face detector
demo system. They are listed below:
- gil
- CMU's Generalized Image Library format. This format only
allows a single band of an image per file.
- gilm
- CMU's Generalized Image Library format. Since the format
supports only single band image files, the "gilm" format is used to
specify that 3 files will be used for a color image. The URL for a
multiband GIL image is must contain a "*", which is converted to "r",
"g", and "b" to get the URLs for the individual bands.
- gif
- Compuserve's Graphics Interchange Format. The format
understood by most WWW browers, such as Mosaic.
- ppm
- One of the PNM formats, used for color images.
- pgm
- One of the PNM formats, used for gray scale images.
- pbm
- One of the PNM formats, used for bitmap images.
- tiff
- A compressed file format (I don't know what the acronym
stands for).
- jpeg
- A lossy-compression file format (the "eg" stands for
Experts Group, I think).
- rle
- Run Length Encoded format, used by the Utah raster toolkit.
- rast
- Sun RASTerimage format.
Please note that not all of these formats have been tested
extensively. Let me know if you have any problems with them, or if
there are any formats that should be added.
