Image Processing Techniques for Assessing Contractility in Isolated Adult Cardiac Myocytes

Figure 5

(a) Two cell shapes in which one of them is larger than the other. (b) first 30 Fourier descriptors superimposed. We observe that their Fourier descriptors are able to capture this change in shape size making the Fourier descriptors variant to scale but invariant to translation, rotation, and starting point. The “contraction” of the shape is as measured by the Euclidean distance of the Fourier descriptors.
