ABSTRACT:
The obtaining of a geometrical effect, with an image, is done by a two-dimensional filter with variable characteristics controlled by a computer to compute the points of a pre-established conversion grid, superimposed on the image, as a function of neighboring points of the original image and of the desired effect. A memory contains the original image. Auxiliary images, obtained by successive reductions, in fixed proportion, of the original image, are stored and a point of the conversion grid is computed by selecting that of the memories for which the reduction factor enables the easiest computation while, at the same time, preserving the quality of the image.
