1 Week 6 Nicholas Baker

2 Tasks for the week Try alternative methods for motion detection
Background subtraction Optical Flow Do full video analysis Implement saliency boosting from motion on color images instead of only grayscale

3

4 Background subtraction

5 Lucas Kanade

6 Lucas Kanade Filtered and Thresholded

7 Adjusted Video

8 Contextual Saliency from Adjusted Video
From orignal video (no motion boosting) From adjusted video (motion boosted)

9 Observations Area with motion is made more salient, but also noisier
Static image saliency picks out almost the exact outline of the foreground object Saliency with motion picks out a slightly larger area surrounding the foreground object, but is more assured of its saliency

10 Color Image Adjustments
Current Method Within areas that have motion For each of the 3 rgb values if that r/g/b value > mean r/g/b of the image average this value with 255
