The Artist

 
Taumban Center Amateur Movie

The construction of the A. Alfred Taubman Student Services Center, the new landmark of the LTU campus, started in September 2004 and got completed on April 7, 2006 - marked by the official Ribbon Cutting Ceremony. The construction could be monitored from the entire globe through the Taubman Live Cam that is still pointed at the building; the image refreshes every minute on weekdays, during daylight ours.


The Movie

This little more than 2.5 minute long time-lapse movie, prepared by my humble self from images captured by the Taubman Live Cam, shows the constructions from November 2004 to the day of the Ribbon Cutting Ceremony, with one image per weekday. (Note however that, although using the same camera's images, this movie is not the same as LTU's official video made and distributed by Marketing & Public Affairs; this is just the creation of an amateur film maker...)

The Making of the Movie

The movie was entirely developed on Windows XP (no political statement here, just a fact :-) ). The following software were instrumental in the process:


     webdump.bat

This little home-grown script can be used to capture a series of live cam pictures for any time lapse movie project; all is needed is a Windows Scheduler Task that invokes the script on a regular basis [once a day for this movie]. The script is responsible for downloading the image file using lynx, and applying a timestamp to the filename in the format

<filename>_YYYY-MM-DD_hh-mmpp.<ext>

The timestamp is generated from the file's modification time, and "pp" refers to the part of the day, which is either "AM" or "PM". This timestamping is made possible by the batch interpreter of Windows 2000/XP, which is vastly enhanced compared to that of previous Windows and MS-DOS versions. For more information on this particular feature, type "for /?" after the command prompt.

However, my big heartache is that the facility does not seem to support the 24-hour time notation, hence the fidgeting with the AM/PM suffixes; this is not only a pain in the neck, but also makes the alphabetic order of filenames different from the chronological order of the files. Furthermore, the value of seconds is not available in the Modification Time script variable, therefore seconds cannot be included in the filename timestamp with this simple method. Pity, pity, pity...!)


     
Watermark Factory

This powerful, yet very easy-to-learn shareware is capable of placing texual or graphic watermarks on images, with a whole host of selectable properties. As one of its major strengths, Watermark Factory can handle a large number of files en masse through watermarking templates called "profiles", which came particularly handy in the making of the Taubman Center Movie. Among the kick-rear features also leveraged in this project is the software's ability to include date and/or time information in the watermark, which is based on either the file's creation time or the picture's shooting time (the latter is extracted from the Exif metadata inside the picture file, if any).

Note: The savvy reader may notice that there is no need for the filenames to contain the exact date and time a live cam picture was captured, because the Watermark Factory gets this info from the file creation date. Indeed, the timestamping of filenames is only necessary to make sure that the consecutively downloaded files will not overwrite each other. Timestamping is a very convenient way to generate unique filenames, without any heavy-duty script programming. However, because of the aforementioned limitation of Windows scripting (<), the method only works if at most 1 file per minute is produced.

Note #2: On a slightly related topic; this is an opportune moment to recognize another very handy tool, a freeware by Tempest Solutions:

Stamp

This program can also timestamp filenames, but unlike webdump.bat, the time information can also come from a file's creation time (including seconds!), or from a host of different time values that are part of the Exif metadata included in digital camera files (images being the most prominent example, albeit not the ones produced by ordinary webcam applications). Sadly, the utility does not seem to support command line execution, so it could not be utilized in the movie project. However, it is a very useful tool, making the otherwise arduous task of organizing digital camera photographs a cake-walk.


     Windows Movie Maker

The hundreds of captured and watermarked live cam pictures were put together into a WMV movie file using Windows Movie Maker v2.1, which is available for download with Windows XP Service Pack 2. It is a simple but very decent tool supporting the most common tricks (e.g. transitions, titles & credits, etc.). It was also able to cope with the challenge posed by the Taubman Center Movie project; my only major issue with the tool was that once a picture is dragged on the Timeline, its duration in the movie cannot be adjusted with the same increments as offered by the Options dialog. This often results in uneven picture durations once the Timeline was messed with, and it cannot be [easily] undone.

ECE Logo Contest Entrants

In the Spring 2004 semester, Dr. Anneberg called upon the

Spring 2004 ECE Logo Contest

so that our beloved Electrical & Computer Engineering Department can establish its coprorate identity. Below are my proud entrants.


1. The Modernist

Inspired by the great spirits of M.C. Escher and Victor Vasarely, the following logo contest entrant was created:

Color version


Black'n'white version

This logo can also be "polymerized," and used as a background (see background).


2. The Seal

The popular seal-style logo comes particularly handy when a compact insignia is desired (for example... on a SEAL! :-) ).

Black'n'white version
