Abstract
(EN)
The present application relates generally to image tiling, including but not limited to systems and methods of fast whole slide tissue tiling. A computing system may identify a first image of a first dimension from which to select one or more tiles. The computing system may perform a reduction operation on the first image to generate a second image of a second dimension. The computing system may apply a thresholding operation on the second image to identify a first set of pixels corresponding to the presence of the feature and a second set of pixels corresponding to the absence of the feature based on an intensity of each pixel in the second image. The computing system may select, from a plurality of tiles corresponding to the first image, a subset of tiles corresponding to the first set of pixels identified from the second image.

La présente invention concerne de manière générale la décomposition d'image, comprenant, entre autres, des systèmes et des procédés de décomposition rapide de tissu de lame complet. Un système informatique peut identifier une première image d'une première dimension à partir de laquelle sélectionner un ou plusieurs pavés. Le système informatique peut effectuer une opération de réduction sur la première image pour générer une seconde image d'une seconde dimension. Le système informatique peut appliquer une opération de seuillage sur la seconde image pour identifier un premier ensemble de pixels correspondant à la présence de la caractéristique et un second ensemble de pixels correspondant à l'absence de la caractéristique sur la base d'une intensité de chaque pixel dans la seconde image. Le système informatique peut sélectionner, parmi une pluralité de pavés correspondant à la première image, un sous-ensemble de pavés correspondant au premier ensemble de pixels identifiés à partir de la seconde image.
