Logarithmic Fuzzy Entropy Function for Similarity Measurement in Multimodal Medical Images Registration

<div>The similarity curves under different patch sizes, red curve <i>l</i> = 3, blue curve <i>l</i> = 7, green curve <i>l</i> = 11, cyan curve <i>l</i> = 15, and magenta curve <i>l</i> = 19. <i>l</i> is the side length of the patch. The dashed curve is M1 function and solid curve is M2 function. <i>x</i> label is rotation degree; <i>y</i> label is similarity value.</div>
