trux_motion

Trux_motion is a program specifically designed to detect motion between any two JPEG images. This software employs the GD library to load JPEG images, and it uses a simple but relatively fast algorithm in detecting motion. To make use of the program, users have to invoke "motion" with three arguments: two JPEG images and a motion threshold value. A sample command would look like this: motion A.jpg B.jpg 1000.

The user-defined motion threshold is the number of pixels that are active. When the number of active pixels goes beyond the motion threshold, motion is detected. If motion is detected, the program's output is zero; otherwise, the output is nonzero. For instance, users can create scripts that output a message when motion is detected, like in the example motion A.jpg B.jpg 1000 && echo "MOTION DETECTED."

Since users may want to detect different levels of motion, the motion threshold value to use will depend on how much motion the user wants to capture. Users can use a motion threshold value of 1 if they need the slightest amount of motion detection. However, larger images from a camera may require a larger motion threshold value to detect motion accurately.

In conclusion, trux_motion is an excellent software tool for detecting motion between images. Its simple yet reliable algorithm can effectively help users track motion, and its customizable motion threshold option offers flexibility to users with different motion detection needs.
