- Resel
A resel is a "res"olution "el"ement - a concept used in
image analysis . It describes the actual spatialimage resolution in an image (or a volume).The number of resels in the image will be lower or equal to the number of pixel/voxels in the image. In an actual image the resels can vary across the image and indeed the local resolution can be expressed as "resels per
pixel " (or "resels pervoxel ").In
functional neuroimaging analysis, anestimate of the number of resels together withrandom field theory is used instatistical inference .Keith Worsley has proposed an estimate for the number of resels/roughness.The word "resel" is related to the words "
pixel " and "voxel ", andWaldo R. Tobler is probably among the first to use the word [http://geog.tamu.edu/~yong/Guru1.htm] .External links
