DEF

A method of increasing an image pixel count by moving pixels an "x" distance, sampling the colors of its neighbors and creating new pixels based on an average of those colors.

OBS

[Bicubic resampling] is a reasonable method of interpolating an image’s pixels, but, on larger scales, yields a soft image.

DEF

Méthode pour augmenter le nombre de pixels d'une image consistant à déplacer ceux-ci sur une distance X, en échantillonnant les couleurs adjacentes et en créant de nouveaux pixels par le calcul d'une moyenne pour ces couleurs.

OBS

Le rééchantillonnage bicubique est une bonne méthode pour réaliser l'interpolation des pixels d'une image mais qui produit, sur une plus grande échelle, une image aux tons adoucis.

CONT

Bilinear filtering is a method of anti-aliasing texture maps. A texture-aliening artifact occurs due to sampling on a finite pixel grid. Point-sampled telexes jump from one pixel to another at random times. This aliening is very noticeable on slowly rotating or moving polygons. The texture image jumps and shears along pixel boundaries. To eliminate this problem, bilinear filtering takes a weighted average of four adjacent texture pixels to create a single telex.

CONT

filtrage bilinéaire : afin d'améliorer les effets visuels des placages de textures, le filtre bi-linéaire interpole de nouveaux pixels entre 2 pixels horizontaux et verticaux. Ainsi, les textures ne se dégradent pas trop quand on les regardent de près.
