impr is a small and fast image processing library
with a simple API. Its functions work mostly on
8-bit image channels, which means that main type
is just (u8 *) or (b8 *) for grey and binary
images respectively. It was intended for use in
real-time processing, so functions are optimized
for speed. It supports segmentation (4 and
8-connected), flood fill, filling object holes,
downscaling and upscaling (with linear
interpolation) by an integer factor, generic
implementations of dilate and erode (+image open
and close), color space conversions between HSVRGB
and YRGRGB, convolutions with Roberts and 2x2
low-pass filters, and common binary image operations.
