In image halftoning, texture is one of the important parameters that has a major effect on image reproduction as well as perception. We propose a halftoning algorithm based on a numerical texture metric and on the threshold accepting algorithm, which provides control of the occurrence of specific textures in the halftoned image. To conserve the image information a simultaneous control of the graytone rendition is implemented. Moreover, additional parameters may be added to control further image characteristics. The algorithm permits control of textures composed of symmetric as well as asymmetric texels and a weighted balance among the different control parameters.
