snapshots from the video of a white marble in a bowl.







after converting it to black and white and getting the position of the ball,information such as location of the ball(x and y), velocity at a certain time, frequency of oscillation can be extracted.



to the left is the graph of the balls position as a function of time. the ball ismoving along 1d (top view) that is why its why component as a function of time is almost contant(flat), while its speed varies because of the effect of gravity. this change in speed can be analyze by the sinusoidal graph.its shows the position of the ball along xaxis.

note: ma'am, inupload ko po ito nung saturday. hindi ko po alam kung bakit nabura pagcheck ko ngayon. i hope you would still consider. thank you.

activity 16-

the images on the right are the histogram of the corresponding images to their left. for this activity i used. a pure yellow ball and red ball with blue green background.



















the images below are the reconstructed images of the balls using parametric and non-parametic method.
(upper left - yellow ball, parametric
upper right - yellow ball, non-paramtric
lower left - red ball, parametric
lower right - red ball, non-paramtric)
