Abstract
Official abstract text for this publication.
A method of processing a digital image. The method comprises: populating ( 100 ) a bilateral grid ( 10 ) comprising a plurality of cells ( 20 ), based on information obtained from the image, each cell comprising at least one value; then cumulatively integrating ( 110 ) the at least one value over the bilateral grid to form an integrated grid comprising integrated values; generating ( 120 ) a modified bilateral grid, comprising computing the sum of the at least one value over a predetermined rectangular box of cells of the bilateral grid, by using the integrated values corresponding to the corners of the box; and slicing ( 130 ) the modified bilateral grid to generate an output image.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of filtering a digital image, comprising: populating a bilateral grid comprising a plurality of cells, based on information obtained from the image, each cell comprising at least one value; cumulatively integrating the at least one value over the bilateral grid in a single pass to form an integrated grid comprising integrated values; generating a modified bilateral grid, comprising computing the sum of the at least one value over a predete…
