Steve on Image Processing

June 27th, 2007

MathWorks developer Dave L. created an Intruder Detection example to demonstrate how Image Acquisition Toolbox and Data Acquisition Toolbox can work together. The program displays live video and audio data acquired from a web cam and sound card. Whenever certain motion or sound thresholds are exceeded, an alarm will sound while the video and audio data are recorded to disk for 10 seconds.

Give it a look.

   Thanks.
   But it should have been said clear WHICH version of the toolbox we need to run this demo. After trying for 30 minutes, and trying upgrading and failed, etc, I only found this nice feature is not available to me yet(I am using 2006b).

   Frustrated—It does give the release (2007a) on the File Exchange page. It’s right under the summary.

   Frustrated—I admit that most developers tend to forget how far our “internal” calendars are offset from “real-world” calendars. That is, most of us finished our R2007a work last December or January, and now many of are already deep into planning R2008a, while many of our customers are still using R2006b or earlier.

   Thanks for pointing out, I was not careful checking that out before complaining.
   I will try to get my hands on the nice demo.

   Frustrated—I’m going to try to get in the habit of putting version-checking code in my own MATLAB Central submissions, so that at least you’ll get a more helpful indication of what’s wrong. I’ll suggest it to others around here as well.

   Hello,

   I am a student and i am new in matlab. I am trying to run your program to get some experience about video capturing and motion detection but i am facing some errors which are beyond my knowledge can you please help me out with these errors ?

   Thanks.

   Tahir—The program is not mine. I simply provided a link to it.
