Software Listing: Logarithms

How can we characterize an image, and does the same characterization yield the same result? In this work, we study one possible characterization, distribution metrics. That is, we assume the desired region of interest has a different probability distribution from its corresponding background. Using this, we present a new distribution metric for image segmentation that arises as a result in prediction theory. Forming a natural geodesic, our metric quantifies 'distance' for two density functionals as the standard deviation of the difference between logarithms of those distributions. Using level set methods, we incorporate an energy model based on the metric into the Geometric Active Contour framework.

Fisher's exact test of 2x4 contingency tables permits calculation of precise probabilities in situation where, as a consequence of small cell frequencies, the much more rapid normal approximation and chi-square calculations are liable to be inaccurate. The Fisher's exact test involves the computations of several factorials to obtain the probability of the observed and each of the more extreme tables. Factorials growth quickly, so it's necessary use logarithms of factorials. This computations is very easy in Matlab because x!=gamma(x+1) and log(x!)=gammaln(x+1). This function is now fully vectorized to speed up the computation.

Fisher's exact test of 3x3 contingency tables permits calculation of precise probabilities in situation where, as a consequence of small cell frequencies, the much more rapid normal approximation and chi-square calculations are liable to be inaccurate. The Fisher's exact test involves the computations of several factorials to obtain the probability of the observed and each of the more extreme tables. Factorials growth quickly, so it's necessary use logarithms of factorials. In Matlab this is very easy using the Gammaln function. The function uses preallocation and vectorization to speed-up the computations.

The purpose of the GUI is to smooth a given signal. The GUI fetches a variable called 'y' from the base workspace. On opening, the variable y is plotted on the axis. When the user slides the slider the smoothed data will be plotted. As the user moves the slide, a P value is changed and the smoothing is improved or worsened depending on the P value and the amount of noise on the variable. On opening the slider value ranges from 0 to 1 and the user can reset the minimum and the maximum value of P. The user can set the GUI to calculate the P value using logarithms. This is done by selecting the logarithmic on the Numeric/Log pop up menu.
