The figure 'mean_variance_change_detect.jpg' shows the detect results for the dataset 'hit_bbgem_1034.root'. We use the mean and standard deviation methods to detect the outlier. The results show that we can detect all the peaks that can be observed by humans.
The figure 'merge_shift_mean_variance.jpg' shows the results for the gradual change. We create simple gradual change and use the test function with order 1 vanish moment. The results show that gradual change can be detected in a large scale. At this moment, the algorithm can not verify the type of change (sudden change or gradual change).
