Assessment of age through still and moving picture (English)
Abstract [sv]

Studier inom åldersbedömning har ofta gjorts med stillbilder av ansikten. Denna studiesyftade till att undersöka om åldersskattningar mellan helkroppsbilder av stillbilder ochrörliga bilder skiljer sig åt. Vidare undersöktes om män bedöms med bättre precision änkvinnor, om precisionen är bättre då bedömaren är av samma kön som den som blir bedömdsamt om åldern underskattas på personer över 40 år och överskattas på personer under 40 år.Datainsamlingen skedde via en webbaserad plattform för enkätundersökningar som för engrupp visade stillbilder och för en annan grupp visade rörliga bilder. Resultatet visade intenågra skillnader i precisionen för bedömning mellan stillbilder och rörliga bilder eller dåbedömningen gjordes inom samma kön (kvinna-kvinna och man-man). Däremot visade detsig att män bedöms med högre precision än kvinnor och att åldern på personer över 40 årunderskattas och att åldern på personer under 40 år överskattas.

Abstract [en]

Studies within age estimation have often used still pictures of faces. The purpose of this studywas to investigate if there is a difference in the precision of age estimation between still andmoving pictures of full bodies. It was also investigated if the precision is higher whenestimating males rather than females, if the precision is higher when the estimation is done bya individual with same sex as the one getting estimated, if the age of people over the age offorty is underestimated and if the age of people under the age of forty is overestimated. Thecollection of data was done through a web based platform for surveys, from which one groupwas showed still full body pictures and the other group was showed moving full bodypictures. The results showed no difference in estimation precision between still pictures andmoving pictures or when the estimation was done within the same gender (female-female andmale-male). However the results showed that males are estimated with higher precision thanfemales as well as that the age of people over the age of forty is underestimated and the age ofpeople under the age of forty is overestimated.
