MMACH 1.4 FREQUENTLY ASKED QUESTIONS WITH ANSWERS 1st July 1997 =================================================================== Index Q1 What is MMACH ? What is the meaning of MMACH? Q2 What else do I need to run MMACH? Q3 What is Khoros? Q4 Where can I get Khoros? Q5 What are the latest versions of MMACH ? Q6 Where can I get MMACH ? Q7 Does MMACH have a WWW Home Page? Q8 Where to find more information about Mathematical Morphology? Q9 I have found a bug that happens on DEC Alpha and Linux systems. The 3x3 dilate and erode on bit images puts vertical streaks in the output image. This doesn't seem to happen with 7x7 kernels or when the image that is being filtered is byte. Q10 When I process some images like image:tools, the result is shifted to the right. What is going on? =================================================================== Q1 What is MMACH ? What is the meaning of MMACH? A1 MMACH is a toolbox for Mathematical Morphology for the Khoros System. MMACH stands for Morphological Machine. Q2 What else do I need, to run MMACH? A2 To be able to use MMACH you need to install Khoros. Q3 What is Khoros? Khoros is for scientists, engineers, data analysts and explorers who need to perform a variety of domain-specific tasks and solve real problems. Khoros is a complete data exploration and software development environment that reduces your time in solving complex problems, allows free sharing of ideas and information, and promotes portability. Unlike other canned, unextensible products, Khoros provides a cost effective, complete prototype to end-solution software development environment. Q4 Where can I get Khoros? A4 Khoros is distributed from several sites around the world. The main site is ftp.khoral.com. WWW site: http://www.khoral.com Q5 What are the latest versions of MMACH ? A5 As there are currently two versions of Khoros: Khoros1.0.5 and Khoros2.2, MMach has version MMach1.1 which runs under Khoros1.05 and MMach1.4 which runs under Khoros2.2 Q6 Where can I get MMACH ? A6 MMach1.1 is available at least in the following site: For Khoros1.05 ftp.ime.usp.br (143.107.45.21), directory: /pub/Toolbox MMach1.4 is available in the following site: ftp://ftp.dca.fee.unicamp.br/pub/khoros/Khoros2/contrib/toolboxes/mmach/mmach-1.3.tar.gz Q7 Does MMACH have a WWW Home Page? A7 Yes, at the WWW adresses: http://www.dca.fee.unicamp.br/projects/khoros/mmach/tutor/mmach.html Q8 Where to find more information about Mathematical Morphology? A8 Look at the resource: http://www.inpe.br/~banon/URLib/index.html Q9 I have found a bug that happens on DEC Alpha and Linux systems. The 3x3 dilate and erode on bit images puts vertical streaks in the output image. This doesn't seem to happen with 7x7 kernels or when the image that is being filtered is byte. A9 Yes, the bit format in MMACH 1.4 is not very reliable in different platforms other than Suns. We have solved this but not released it yet. Meanwhile, convert your images to byte before processing with any MMach operator. Q10 When I process some images like image:tools, the result is shifted to the right. What is going on? A10 It is a problem with Map segment. Remove the map segment and proces the image normaly.
