This RCO allows a user to track movement of a feature within a set of images. Once tracking is activated, the user can mark a location on an image, advance to the next image, and mark the new location of the feature. At that time, either the distance or the speed of the feature's movement will be shown, depending on settings in the XML configuration file.
The instructor will gather a set of images, and must determine the units per pixel, provided as an XML parameter, in order to correctly compute speed or distance.
The sample XML file provided below must be populated with appropriate data (filenames, ancillary information about the images, etc.) and placed in the same location as the HTML file used to access and present this RCO.
This link will bring up a separate browser window with a page that uses this RCO.
Create your XML file one of two ways:
Edit this sample Feature Tracker XML file
Generate your XML automatically with this link.
