Video-rate frame by frame detection using SURF. (A), (B) Mean time (black line) and 95% CI (gray shadow) for the detection of keypoints in culture and slice images sequences, respectively. (C), (D) Examples of ROI detection (black square) and good matches (black circles) at different time points. (E) Examples of ROI detection in 4 levels of manual focus changes. (F) Mean amount of good matches in culture and slice image sequences.
