FD IMM HIPS programs, 3 April 1997

Synopsis

This is a synopsis of some freely distributed (FD) HIPS programs written by members of the Section for Image Analysis at IMM, the Department of Mathematical Modelling at the Technical University of Denmark. The programs are developed and run on a network consisting of HP, SGI, Sun, IBM, DEC, and NeXT UNIX engines plus an increasing number of PCs running Linux. The Section for Image Analysis is headed by Professor Knut Conradsen. The software can be obtained here.
