Visual comparison of film trailers through use of Matlab (English)
Abstract [en]

The primary intention of this paper was to visually compare film trailers without considering semantic information, through use of a self-developed Matlab program, resembling that of human perception. Circa 150 people participated in an online survey where they were shown two film trailers and asked to rate their visual similarities. The result from the program was weighted against the survey results in such a way that the weights corresponded to a 75% accuracy between the program’s and the participant’s (for participants with prior experience in the field of photography and/or film) comparisons.

How accurate can we compare still images from film trailers, and find similar trailers for the human viewer, by analyzing saturation, color tone, contrast and lightness with a self-developed Matlab program.

Abstract [sv]

Syftet med undersökningen var att jämföra filmtrailers visuella element, bortsett från semantiskt innehåll, med hjälp av ett egenutvecklat Matlabprogram, likt den mänskliga perceptionen. En undersökning, med cirka 150 deltagare, gjordes via internet där deltagare fick se på två filmtrailers (utav 13 möjliga trailerpar) och gradera dess visuella likhet/olikhet.  Resultatet från programmet viktades sedan mot enkätsvaren sådant att viktningen gav en 75% likhet mellan programmets och deltagarnas (för deltagare med tidigare erfarenhet av foto och film) jämförelser. Det vill säga i tre av fyra fall kunde vårat program hitta samma likhet/olikhet i filmtrailerparet.

Hur väl kan vi med programmet Matlab jämföra stillbilder från filmtrailers utifrån färgmättnad, färgton, kontrast, och ljushet, och därmed hitta (för åskådaren) visuellt liknande trailers?
