Week 6 Nicholas Baker

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

Background subtraction

Lucas Kanade

Lucas Kanade Filtered and Thresholded

Adjusted Video

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

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

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
