ripa (version 2.0-1)

R Image Processing and Analysis

Description

A package including various functions for image processing and analysis. With this package is possible to process and analyse RGB, LAN (multispectral) and AVIRIS (hiperspectral) images. This packages also provides functions for reading JPEG files, extracted from the archived 'rimage' package.
