Phase contrast microscopy sequence of U373 cells.

The .zip file contains .CSV file for frame each line contains: #cell, #frame, x position, y position Cell cultures in Falcon plastic dishes maintained at 37 C° were observed and recorded automatically every 4 min. The images were acquired under a phase-contrast microscope (Olympus, model IX50, magnification ratio 10:1), with a charge-coupled device video camera (Hitachi Denshi, modelKP-M1E/K-S10) coupled with an acquisition board (32-bits Matrix Vision PC-GRAB-GI frame grabber). The image dimensions are 700 500 pixels (with a pixel resolution of 0.92µm at the magnification ratio abovementioned) discretized on 256 gray levels (8 bits/pixel). The images are compressed using jpeg compression.
