The Projectile Motion with Angry Birds lab uses the Tracker video analysis tool to measure and analyze the motion an angry bird projected from a slingshot to hit a pig.<br /><br />The zip file contains the lab handout, a video, and the Tracker…
What kind of power would you need to overcome this obstacle? Why is this such a difficult thing to do? Well, a ninja trying to climb this ladder not only has to do something like a pull-up (no easy feat) he has to end the pull-up with enough vertical velocity so that he can be “airborne” long enough for him to move the bar to the next level. Really, this is the part that makes it tough and this is the part that I want to calculate the power for. Let’s go.
We propose a joint optical flow and principal component analysis (PCA) method for motion detection. PCA is used to analyze optical flows so that major optical flows corresponding to moving objects in a local window can be better extracted. This joint approach can efficiently detect moving objects and more successfully suppress small turbulence. It is particularly useful for motion detection from outdoor videos with low quality. It can also effectively delineate moving objects in both static and dynamic background. Experimental results demonstrate that this approach outperforms other existing methods by extracting the moving objects more completely with lower false alarms.
