  4. Contact Information • Instructor • Rolando Raqueño • E-mail (rolo@cis.rit.edu) • Phone (475-6907) • Office (76-3108) • Office Hours • Monday and Wednesdays • 2:00-2:50 PM • Other times by appointment Rolando V. Raqueño

  5. Course Objective • Basic proficiency in UNIX operating system for problem solving in imaging • Learning elementary programming constructs in IDL and refinement of programming skills • Useful data manipulation techniques • Establish software development, validation, and documentation practices Rolando V. Raqueño

  6. UNIX Proficiency • Basic UNIX Environment Proficiency • X-Windowing Environment (networked) • The universally available editor “vi” • Navigation and File Manipulation • Understanding Basic Computing Data Type and Hardware differences • Documentation Tools (LaTeX) Rolando V. Raqueño

  7. Why UNIX? • Why the UNIX Environment? • Very mature technology • Maintains a large base of high quality “copy-left” programs • LINUX is “free” and can run on a 386 PC • Remote computing is a natural part of UNIX • Very close control of the computer • Minimalist approach to computing Rolando V. Raqueño

  8. Shortcuts and Timesavers • Learn shortcuts and time savers when solving programming related problems (when not to do traditional program) • a.k.a “Stupid UNIX Tricks” • Shell Scripts • AWK & SED • Makefiles • Computing applications in an imaging context Rolando V. Raqueño

  9. Compiling Traditional Programs in UNIX • Legacy FORTRAN and C code requires some knowledge of how to compile these programs • Tools to aid in compiling (makefiles) • Common pitfalls • Setup tips for input and output data files Rolando V. Raqueño

  10. Imaging Concepts • Application in an imaging context • Bi-level • Monochrome • Color • Multispectral • Hyperspectral Rolando V. Raqueño

  11. IDL Environment • IDL Basics,Syntax, and Semantics • Your responsibility to get started • IDL Graphical User Interface (GUI) development • Enable batch processing • How IDL interacts with the UNIX environment. Rolando V. Raqueño

  12. This Course is/is not • This course is not... • an algorithm course in image processing or computational theory • a programming course in C/C++ • This course will... • give you a means to prototype and test image processing algorithms • provide a foundation for prototyping algorithms that can be translated into traditional programming languages Rolando V. Raqueño

  13. This course is not… • This course is not... • Designed to make you a software engineer • This course will... • Give you the skills to communicate with software engineers about your algorithm, expected inputs, and expected output • Provide give them necessary concepts, specifications and test cases, i.e., The working prototype Rolando V. Raqueño

  14. LaTeX • Course will introduce fundamental LaTeX concepts • Help with documentation • Help with your thesis/dissertation Rolando V. Raqueño

  15. Documentation, Documentation • This course will... • Teach you about documentation in the form of source code control. RCS or SCCS under CVS • Inherently lacking in other operating systems (OS) Rolando V. Raqueño

  16. Prerequisites/Expectations • Experience in a high level programming language (e.g. C, FORTRAN, BASIC, PASCAL, ADA, etc.) in the last 20+ years. • Ability to make lots of mistakes (and remember them) • Ability to deal with frustration, and know when to quit • Good Typing Skills a plus • Good Technical Writing Skills • Be able to generate a User’s Guide Rolando V. Raqueño

  17. Milestones in the Progression of Programming Experience • Programming in traditional languages • Beginning (Monolithic programs) • single letter variables • Loops and maybe an occasional GOTO • Intermediate ( Use of subroutines and functions) • Favor Local variables rather than Global Variables • Understand parameter passing schemes • Advanced (Structures and abstract data types) • More meaningful variable names Rolando V. Raqueño

  18. Milestones in the Progression of Programming Experience • Programming in traditional languages • Learning that hand-optimizing code at the development is simply not worth the time • Learning to separate the algorithm from the bells and whistles (i.e., input and output code) • Creating a library of “tools” • Use of revision control utilities along with README’s and formal documentation. Rolando V. Raqueño

  19. Milestones in the Progression of Programming Experience • Programming in non-traditional languages • Thinking about the problems in terms of matrix and vector operations • Avoiding loops and conditionals • Thinking about the “Non-expert” by designing the Graphical User Interface (GUI) • *Realizing that there is no single software tool that solves everything. Rolando V. Raqueño

  20. Course Grading • Final IDL GUI Project 40% • Presentation and Report • Mid-term Exam 30% • Programming Assignment(s) 20% • Will be questions in Mid-term • Quizzes (every week) 10% Rolando V. Raqueño

  21. Course Text • Liam Gumley’s Practical IDL Programming (Required) • Unix Power Tools (Required) • Research Systems Incorporated (RSI) • Online Manuals • Using IDL • Building IDL Applications • Reference Manuals • Cliff Stoll’s The Cuckoo’s Egg • (Holiday Required Reading) Rolando V. Raqueño

  22. Other References • Text • Learning the UNIX Operating System • UNIX Power Tools • On-line • News groups • comp.lang.idl-pvwave • Web sites • www.rsinc.com • www.ctan.org (LaTeX references) Rolando V. Raqueño

  23. Other References • Notes • These Powerpoint slides will be available on-line for your reference. • These Notes will be available the Monday each week. • If not, old notes will be available • http://www.cis.rit.edu/~rvrpci/teaching/simg726/20012 • DL class • http://www.cis.rit.edu/class/simg726 • Send me mail and I will reply with the location of this year’s site.
