The function of the Tracker Module is the processing of the video recordings and the determination of the observed object's XY coordinates in each frame. Each frame goes through a processing chain and each step of the processing chain can be customized according to the requirements of the recording in question. Custom processing chains created for different types of recordings can be saved and used as templates for recordings with similar properties.
During binarization, separation of the foreground from the background is performed. The output image is composed of black and white pixels with no shades in between – the foreground is white and the background is black. Some of the pixels can be miscategorized, but these errors can be easily corrected using various post-processing algorithms. For more information see Thresholders.
Some of the pixels can be miscategorized during binarization. This can cause the fragmentation of the tracked object, noticeable by the appearance of flashing pixels in the frame. Errors such as these can be easily corrected by using the appropriate post-processing algorithms. For more information see Postprocessors.
In case the tracked object is lost, click on the button to open the Track Editor.
At the end of the tracking procedure, the coordinates of the trajectory can be saved in a text file by clicking on the button.
The containing the settings in steps 5 to 9 can be saved and reopened, which can speed up the processing of similar recordings.
The containing all settings and information in steps 1 to 13 can be saved and reopened in case batch processing is required.
