Why finance professors should be teaching Nietzsche

<p><strong>Abstract:</strong> Retinal images (RI) are widely used to diagnose a variety of eye conditions and diseases such as myopia and diabetic retinopathy. They are inherently characterised by having nonuniform illumination and low-contrast homogeneous regions which represent a unique set of challenges for retinal image registration (RIR). This paper investigates using the expectation maximization for principal component analysis based mutual information (EMPCA-MI) algorithm in RIR. It combines spatial features with mutual information to efficiently achieve improved registration performance. Experimental results for mono-modal RI datasets verify that EMPCA-MI<br>together with Powell-Brent optimization affords superior robustness in comparison with existing RIR methods, including the geometrical features method.</p> <p><br><strong>Index Terms</strong>— Image registration, principal component analysis, mutual information, expectation-maximization algorithms, retinopathy.</p> <p> </p> <p><strong>Poster presented at</strong>: 38th International Conference on Acoustics, Speech, and Signal Processing<br>(ICASSP), 26th to 31st May 2013, Vancouver, Canada.<br>doi: 10.1109/ICASSP.2013.6637824</p
