01. Sidewalk01

(Pedestrian Throughway)

Shot Description: Shot near Cognitive Science Building and singing tree. Three angles: (1) Oblique - 6-foot tripod fully extended above heads and placed on boulder to give slight birds-eye-view, facing east towards library walk. (2) Front - eye level, two tripod legs on crack in cement facing west, (3) Side - eye-level in dirt facing north.

Filming Status:

Still Shots -

(1) Oblique Angle - Missing ‘medium’ traffic level. However, can make this up using a ‘medium-high’ class.

(2) Front Angle - Complete. Two slightly different versions.

(3) Side Angle - Missing: ‘high’ level. Can’t shoot this level until october.

Panning Shots -

No Panning shots were filmed due to time constraints.

Traffic-Level Classifier Description: Discriminating between high, medium, and low flows of pedestrian traffic. Three experiments, one per angle.

(1) Oblique - Initial Experiment Results:

Although a distinct ‘medium’ class was not shot yet, we were able to achieve high accuracy using two levels of high. (i.e. ‘low-high’ & ‘high-high’).

md_error_mean = 0.1659 = 83.41% Accurate

kl_error_mean = 0.2505 = 74.95%

kl_svmerror_mean = 0.3141 = 68.59%

ikl_error_mean = 0.3676 = 63.24%

ikl_svmerror_mean = 0.3004 = 69.96%

(2) Front - Initial Experiment Results:

Waiting on results. ETA: less than one week.

(3) Side - Initial Experiment Results:

Waiting on ‘high’ class. ETA: October.
