14.02.2015 · In a perfect world the filling of bin should be straight line measurement and when overflow is reached it should be a straight line. If this was the case i could take the second derivative to find the change is slope. Unfortunately this is not the case and when i take the second order derivative I get the the results shown in the attached picture.

Jul 17, 2018 · I want to find the time where the slope of the graph starts to decrease. In this case, the graph is a measurement of the foot angle of someone walking. I would like to use MATLAB to detect when the person starts walking, which in this case seems to be at around 2 seconds. The problem is that there is a dip in the graph right at the beginning.

Mean or slope of data between change points, returned as a vector, matrix, multidimensional array, table, or timetable. If the change point detection method is 'mean' or 'variance' , then S1 contains the mean for each segment. If the method is 'linear', then S1 contains the slope for each segment. S1 has the same type as the input data.

Scene Change Detection Results The model segments the video using the following steps. First, it finds the edges in two consecutive video frames, which makes the algorithm less sensitive to small changes. Based on these edges, the model uses the Block Processing block to compare sections of the video frames to one another.
