Logarithmic Fit First, the Leaf scanner was modeled as a logarithmic function. As shown below, the logarithmic fit fails to model the scanner accurately. The Leaf was also modeled as a function of an exponential. Again, this model is also somewhat inaccurate. To further illustrate the inaccuracy of these models, the following table displays the deviations of the three models from the actual data.
All deviations are in pixel values.
As shown above, the power fit is the most accurate of the three models. Therefore, the power model was chosen as the model for the Leaf scanner.
