image processing and analysis library
Project homepage: http://www.leptonica.org/
Description
Leptonica is a pedagogically-oriented open source site containing
software that is broadly useful for image processing and image analysis
applications.
Featured operations are
* Rasterop (a.k.a. bitblt)
* Affine transformations (scaling, translation, rotation, shear) on
images of arbitrary pixel depth
* Binary and grayscale morphology, rank order, and convolution
* Seedfill and connected components
* Image transformations combining changes in scale and pixel depth
* Pixelwise masking, blending, enhancement, arithmetic ops, etc.
Ancillary operations include
* I/O for standard image formats
* Utilities to handle arrays of image-related data types
* Utilities for generic stacks, queues, heaps and lists; and for
byte queues and arrays of numbers and strings
