biOps-package: Basic image operations and image processing

Description Details Author(s)

Description

This package includes arithmetic, logic, look up table and geometric operations. Some image processing functions, for edge detection (several algorithms including roberts, sobel, kirsch, marr-hildreth, canny) and operations by convolution masks (with predefined as well as user defined masks) are provided. Supported file formats are jpeg and tiff (it requires libtiff and libjpeg libraries installed).
