Graphics Muse Tools Graphics Muse Tools is a collection of plug-ins, brushes, and patterns for use with the GNU Image Manipulation Program. GREYCstoration GREYCstoration is an image regularization algorithm which processes an image by locally removing small variations of pixel intensities while preserving significant global image features, such as sharp edges and corners. The most direct application of image regularization is denoising.

JPEG Disk Optimizer (commercial) JPEG Disk Optimizer is a JPEG optimizer / compressor. It can remove spots, or dead pixels, and gaussian noise from the image, significantly improving both the appearance and file size. jpegextractor jpegextractor is a command line tool to extract JPEG streams from arbitrary files or standard input. jpegextractor has yet another approach, it uses the fact that valid binary JPEG streams start with the byte sequence ff d8 ff and end with ff d9. It copies all of those streams to new files. As jpegextractor simply looks for the two sequences it does not have to know the format of the encapsulating file and thus works with all formats that embed JPEG streams. jpegpixi JPEG pixel interpolator: to interpolate pixels in JFIF images (commonly refered to as "JPEG images"). This is useful to correct images from a digital camera with CCD defects. For example, if one pixel is always bright green, this pixel can be interpolated away with jpegpixi.

The input is a bitmap (PBM, PGM, PPM, or BMP format), and the default output is an encapsulated PostScript file (EPS). A typical use is to create EPS files from scanned data, such as company or university logos, handwritten notes, etc. The resulting image is not "jaggy" like a bitmap, but smooth. It can then be rendered at any resolution. potrace can currently produce the following output formats: EPS, PostScript, PDF, SVG (scalable vector graphics), Xfig, Gimppath, and PGM (for easy antialiasing). potracegui potracegui is a GUI interface for potrace, a great program for tracing bitmapped images. ppmcaption ppmcaption adds text to images.
