Quantitative Analysis of Intracellular Motility Based on Optical Flow Model

Figure 4

The instantaneous velocity extracted from 4 kinds of data (Celldata_20, Celldata_40, Celldata_60, and Celldata_80), by three kinds of optical flow approaches (the HS model, the Brox model, and the proposed method).

(a) The HS model

(b) The Brox model

(c) The proposed method
