Texture synthesis through so-called ‘smart copying’ requires a seamless meshing of texture subparts. Current systems first select subparts that seem to globally fit well and then optimise the cut between them on a rather local scale. This order of first selecting patches and then caring about the seamless meshing reduces one’s leeway in the choice of seamless cuts to a small zone of overlap bet...

Structuring of surface meshes is a labor intensive task in reverse engineering. For example in CAD, scanned triangle meshes must be divided into characteristic/uniform patches to enable conversion into high-level spline surfaces. Typical industrial techniques, like rolling ball blends, are very labor intensive. We provide a novel, robust and quick algorithm for the automatic generation of a pat...

This paper describes an efficient technique for out-of-core rendering and management of large textured terrain surfaces. The technique, called Batched Dynamic Adaptive Meshes (BDAM) , is based on a paired tree structure: a tiled quadtree for texture data and a pair of bintrees of small triangular patches for the geometry. These small patches are TINs and are constructed and optimized off-line w...

We propose a technique, called TextureMontage, to seamlessly map a patchwork of texture images onto an arbitrary 3D model. A texture atlas can be created through the specification of a set of correspondences between the model and any number of texture images. First, our technique automatically partitions the mesh and the images, driven solely by the choice of feature correspondences. Most chart...

Sacred groves are the traditionally managed small or large patches of relict vegetation conserved on religious beliefs and representing climax vegetation. These sacred have some set traditional rules protocols called taboos, which key to conservation diversity within. Interestingly, every grove has its legends, myths, lores an integral part groves. act as a gene bank for threatened endemic flor...

Background: Segmental pigmentation disorder (SegPD) is a rare type of cutaneous dyspigmentation. This hereditary disorder, first described some 20 years ago, is characterized by hypo and hyperpigmented patches on the trunk, extremities and less likely on the face and neck. These lesions are considered as a type of checkerboard pattern. Case Presentation: Herein, we present a 26-year-old male...

Background: The description on patients with pigmented back patches is rarely reported in the literature. We decided to study the clinicopathological aspects of these patients for reaching a better understanding of this disease.Method: In this study, the clinicopathological aspects and probable responsible factors in the manifestation of posterior pruritic pigmented patches in patients referred...
