Hardware and software system for biotesting natural water bodies
Abstract
A hardware and software system for bioassays is proposed, which counts the number of mobile biological objects (ciliates) within a microscope's field of view. Video recording can be performed using simple tools, including a mobile phone camera. The program for counting the number of moving objects within a microscope's field of view is written in Python and utilizes OpenCV library functions. The user interface allows for adjustments to the number of frames processed, the brightness threshold, and the number of pixels for image blur. The program can be easily adapted for use with the simplest equipment, in frame-by-frame or continuous shooting modes. A comparison with other known bioassay tools is provided.
