Scale-Dependent and Example-Based Grayscale Stippling
We present an example-based approach to synthesizing stipple illustrations for static 2D images that produces scaledependent results appropriate for an intended spatial output size and resolution. We show how treating stippling as a grayscale process allows us to both produce on-screen output and to achieve stipple merging at medium tonal ranges. At the same time we can also produce images with...
متن کاملInteractive Hatching and Stippling by Example
We describe a system that lets a designer interactively draw patterns of strokes in the picture plane, then guide the synthesis of similar patterns over new picture regions. Synthesis is based on an initial user-assisted analysis phase in which the system recognizes distinct types of strokes (hatching and stippling) and organizes them according to perceptual grouping criteria. The synthesized s...
متن کاملA Nonlinear Grayscale Morphological and Unsupervised method for Human Facial Synthesis Based on an Example Image
Human facial generation of example image is used as a requirement for biometric applications for the purpose of identifying individuals. In this paper, face generation consists of three main steps. In the first step, detection of significant lines and edges of the example image are carried out using nonlinear grayscale morphology. Then, hair areas are identified from the face of sample. The fin...
متن کاملHalftoning and Stippling
One important origin of non-photorealistic computer graphics comes from printing technology. Halftoning is a reproduction technique for photography in printing. The continuous tones of the images are represented by fulltone dots of varying size, shape and density. While printing technology brought this to perfection over time, computer graphics researchers developed methods that modified this p...
