Image-processing software for detecting particles moving in micro-pier structure driven by the contractions of cardiomyocyte bridge

This program (main.py, OpenCV, written by Python) provides the XY-position of particles in each frame of the original movie (255.m4v) and a movie with circles indicating the particle positions (255_result.mp4). For the analysis of particle displacement, we used the distribution of brightness around the target particle as a template, where the area of the particle in a movie image is brighter than the other area (255_result.txt). The detected XY-position of the template was determined as the XY-position of the particle in the frame.
