Genetic programming is used to automatically synthesize procedural textures for 3D surfaces. The GP system evolves textures with similar colour and surface characteristics as training textures sampled on 3D models. The texture language includes mathematical operators, colour and noise functions, as well as surface information for the point being rendered, such as coordinates, normal, and gradie...

Since image processing aimed at reducing image noise can also remove important texture, standard methods for evaluating the capture and retention of image texture are currently being developed. Concurrently, the evolution of the intelligence and performance of camera noise-reduction (NR) algorithms poses a challenge for these protocols. Many NR algorithms are ‘content-aware’, which can lead to ...

The tensile deformation response and texture evolution of aluminum alloyed Hadfield steel single crystals oriented in the h169i direction is investigated. In this material, the strain hardening response is governed by the high-density dislocation walls (HDDWs) that interact with glide dislocations. A microstructure-based visco-plastic self-consistent model was modified to account for mechanical...

This communication introduces a fast material- and process-agnostic modeling approach, not reported in the open literature, that is calibrated for predicting evolution of texture metal additive manufacturing stainless steel 304L as function process parameter, namely laser scanning speed. The outputs model are compared against independent validation experiments same material system show excellen...

On a curved surface the front of a point wave evolves in concentric circles which start to overlap and branch after a certain time. This evolution is described by the geodesic ow and helps us to understand the geometry of surfaces. In this paper we compute the evolution of distance circles on polyhedral surfaces and develop a method to visualize the set of circles, their overlapping, branching,...
