- Technology and Communication
- Daniel Minoli

-
- Recently I was involved in an interesting design problem of putting
- together a large image storage/retrival application. I started from
- scratch (on images) and gradually learned bits and pieces about issues
- in image databases, using a heterogenous mix of drinking from
- newsgroups, asking questions on them, trying out pieces of the design
- on friends, reading product literature, and keeping my wits about me.
-
- I was looking for a book which would help me get a more structured
- grip of the field. While browsing in the Computer Literacy Bookstore
- (across the road from Frys in the bay area, a lovely place!), this
- book caught my eye. The title is a bit forbidding -- "corporate
- environments" brings to mind something aimed at big iron
- administrators storing images on IBM mainframes.
-
- The TOC was quite reassuring for the technical thug in me. Let me
- reproduce it here:
-
- 1. Introduction and Overview
- 2. Imaging systems in corporate environments
- 3. Technical principles of resolution and color
- 4. Imaging entry--capture systems
- 5. Output systems
- 6. Compression and Storage Techniques and Standards
- 7. Storage Technology
- 8. Local Area Networks: Imaging Platforms
- 9. WAN services and technologies for imaging systems.
-
- The chapters are quite self contained, and you can benefit from
- reading groups of chapters in isolation. I will hence talk about
- these groups separately.
-
-
- 1. Introduction and Overview
- 2. Imaging systems in corporate environments
-
- Little here was new for me, but they are a useful 50--page birds eye
- view of the field. My only complaint here, one that is applicable to
- many parts of the book, is that it is quite dated. For a book
- published in 1994, it seems remarkably out of tune with the state of
- the art as of today. I wish publication lags were shorter.
-
- Of course, this is also a reflection on how fast things change in this
- field. :-( Perhaps FAQs are a better way of disseminating such
- knowledge.
-
-
- 3. Technical principles of resolution and color
-
- This was the most "new" chapter for me, for I had no roots in color
- before it. The book takes this up in depth and while I don't need
- color for my problem, I now have some idea about the issues, and I
- know where to look when I need more.
-
- This is the most technical chapter of the book. It is not afraid to
- use mathematics. I really enjoyed this attitude of offering deep
- fundas, but I suspect many a "corporate environment" won't need this
- kind of understanding of color. I suppose knowing things in-depth is
- good for the soul and builds character.
-
- Nitpicking. In Table 3.1, it is "unfair" showing the Macintosh
- Classic as 640 x 400 resolution.
-
-
- 4. Imaging entry--capture systems
- 5. Output systems
-
- This is a reasonably good treatment of scanners, file formats,
- printing bitmaps, etc. The "output systems" chapter has a strong
- emphasis on the problems of colour. I didn't mind, since I know a
- good deal about the b&w side of life, but it felt like an omission.
-
- References to specific file formats and software are glaringly weak in
- not giving pointers to net software, such as pbm, the independent jpeg
- group, gs, etc. I think knowing of these is really valuable for
- anyone working with image files. This is germane for the next chapter
- too. The author doesn't appear to be much net--aware.
-
- Nitpicking. Many scanners routinely refer to a distinction between
- the "optical resolution" and what you finally get using "software
- interpolation". I have always wondered how this was done. The book
- doesn't tell how.
-
- I have also been curious about a related topic: how do you print a 400
- dpi fullpage bitmap on (say) a 300 dpi or 600 dpi laser printer? The
- book doesn't bring up this question.
-
- The entire problem of speed of printing bulky bitmaps is not touched
- upon.
-
-
- 6. Compression and Storage Techniques and Standards
-
- This was a nice chapter, with an emphasis on JPEG. I had a good deal
- of prior background, but still enjoyed reading it. I was hungry for
- more details and practical examples. E.g. it would have been nice to
- have a dozen or so samples of input matter and compression obtained in
- practise using different algorithms.
-
-
- 7. Storage Technology
-
- I know this area quite well and the chapter left me cold. One problem
- is that many of the specific pieces of information are dated. There
- are subtle weaknesses in the text which were disappointing.
-
- I guess if you had to do an image system and didn't know a lot about
- storage technology to start with, then this chapter is definitely good
- reading. But I wish it had been done more perfectly.
-
-
- 8. Local Area Networks: Imaging Platforms
- 9. WAN services and technologies for imaging systems.
-
- I started out with a reasonably good idea about TCP/IP and how I could
- use it for image problems. These two chapters are not strongly about
- imaging systems (notwithstanding the title) though this is perhaps
- inevitable.
-
- They are like a capsule summary of computer networking. If anything,
- they could easily be confusing. The reader will be subjected to a
- barrage of technology options, and will not see how easy networking
- actually is when putting together a TCP/IP network using off the shelf
- technologies. Instead, the reader will get one section each on T1 and
- FT1 lines, X.25, ISDN, ATM, SONET, frame relay etc. The book does not
- _evaluate_ these options and show which will be superior when. It
- tends to catalog them. I think it makes the entire networking
- situation more complicated than it really is. A "how--to" on making a
- TCP/IP network fly using mainstream communications technologies would
- have been more useful to practitioners in corporate environments.
-
-
- In all, I'm glad I read the book, and I would recommend it to anyone
- who plans to work with largescale image problems. I would strongly
- recommend that you get uptodate information, from vendors and from the
- net to supplement the book. I would strongly recommend not relying on
- the book for "the big picture" of storage technologies and computer
- networking. This is not one of the memorable technical books I've
- seen in my life, but it's useful all the same.
