Comparison of parts of the summaries on ADL P_07.mp4 with various λ values at the optimization step. This video shows the scenes, “going to a laundry room” and “using a computer.” Each row contains the frames in the first or second cluster of the video. The first two columns show the frames obtained with the minimum (a) a _i or (b) d _i values, and (c–e) show the resultant keyframes with λ=0, λ=10¹, and λ=10², respectively. In the first row, even though the frames of (a) and (e) have high contrast, they are less appropriate ones as story board images of “laundry room,” while the frames of (b–d) would be more appropriate ones
