| description | - 62 COLOUR GRADIENTS FROM SMOOTH-PROFILE AND SHARP-PROFILE PATHS USING EFFICIENT SOLVING A method of generating an image from a plurality of diffusion curves each having at least one value constraint on a side of the curve. At least one diffusion curve is a blocking curve for which colour values on either side of the blocking curve are substantially unaffected by constraints of proximate curves on the corresponding other side of the blocking curve. The method forms a vector representation of each of the plurality of curves relative to a grid, each vector representation of a curve having a plurality of line segments, obtains weights for each segment based on the curve constraint values of curves contributing to a region bounded by at least one of a closed blocking curve or a boundary condition associated with an edge of the generated image, and generates the image according to the line segments and the obtained weights associated with each of the line segments. 9005461_1 P106721_speci lodge '10 Generate solved image representation (line segments and coefficients) Evaluate & solve image target o representation at target resolution resolution Fig. 1 |
