Overview of the shot-level data extraction pipeline.

Figure 2
Schematic definition of the region of interest (ROI) used for color feature extraction. The ROI is obtained by removing 12.5% from all four borders of the frame.

Figure 3
Schematic illustration of deterministic within-shot sampling (five frames at 1/6–5/6 of shot duration) and the reuse of the same frames for color and face/shot-scale feature extraction.
Table 1
Film-level ASL for 30 Kurosawa films (raw and truncated) compared with Cinemetrics references (Salt prioritized; otherwise community). “Not checked” indicates the community column was not consulted because a Salt value exists; “Missing” indicates no matching entry.
