We introduce halftoning as a general primitive for real-time non-photorealistic shading. It is capable of producing a variety of rendering styles, ranging from engraving with lighting-dependent line width to pen-and-ink style drawings using prioritized stroke textures. Since monitor resolution is limited we employ a smooth threshold function that provides stroke antialiasing. By applying the ha...
Replacement reactions ('pseudomorphism') commonly occur in Nature under a large range of conditions (T 25 to >600 degrees C; P 1 to >5 kbar). Whilst mineral replacement reactions are often assumed to proceed by solid-state diffusion of the metal ions through the mineral, many actually proceed via a coupled dissolution and reprecipitation (CDR) mechanism. In such cases, a starting mineral is dis...
The Iranian textures in the Safavid era are associated with some phenomena such as symbolism and myth. These textures contain some motifs that indicate the beliefs and ideas of the Iranian people, and these motifs have preserved the concepts over time. The dragon is one of these symbolic motifs whose presence can be traced back to the oldest literary sources in Iran's history. Dragon is referre...
Recent research on texture synthesis suggests that characterisation of those properties of textures to which human observers are sensitive may be provided by the histograms of the coefficients of a wavelet decomposition. In this study we examined the properties of wavelet histograms that affect texture discrimination by measuring observer sensitivity to differences in the wavelet histograms of ...
