This paper describes a new method for contouring signed grid whose edges are tagged by Hermite data (i.e; exact intersection points and normals). avoids the need to explicitly identify process "features" as required in previous methods. Using new, numerically stable representation quadratic error functions, we develop an octree-based simplifying contours produced this method. We next extend our these simpli£ed octrees. imposes no constraints on octree (such being restricted octree) requires...
Constructing a function that interpolates set of values defined at vertices mesh is fundamental operation in computer graphics. Such an interpolant has many uses applications such as shading, parameterization and deformation. For closed polygons, mean value coordinates have been proven to be excellent method for constructing interpolant. In this paper, we generalize from 2D polygons triangular meshes. Given P , show these are continuous everywhere smooth on the interior . The linear...
Pancreatic ductal adenocarcinoma is a lethal disease with limited treatment options and poor survival. We studied 83 spatial samples from 31 patients (11 treatment-naïve 20 treated) using single-cell/nucleus RNA sequencing, bulk-proteogenomics, transcriptomics cellular imaging. Subpopulations of tumor cells exhibited signatures proliferation, KRAS signaling, cell stress epithelial-to-mesenchymal transition. Mapping mutations copy number events distinguished populations normal transitional...

We present a robust method for repairing arbitrary polygon models. The is guaranteed to produce closed surface that partitions the space into disjoint internal and external volumes. Given any model represented as soup, we construct an inside/outside volume using octree grid, reconstruct by contouring. Our novel algorithm can efficiently process large models containing millions of polygons capable reproducing sharp features in original geometry.

Image/video editing by strokes has become increasingly popular due to the ease of interaction. Propagating user inputs rest image/video, however, is often time and memory consuming especially for large data. We propose here an efficient scheme that allows affinity-based edit propagation be computed on data containing tens millions pixels at interactive rate (in matter seconds). The key in our a novel means approximately solving optimization problem involved propagation, using adaptive...
Paper architectures are 3D paper buildings created by folding and cutting. The creation process of architecture is often labor-intensive highly skill-demanding, even with the aid existing computer-aided design tools. We propose an automatic algorithm for generating given a user-specified model. grounded on geometric formulation planar layout that can be popped-up in rigid stable manner, sufficient conditions surface to from such layout. Based these conditions, our computes class containing...
Abstract Building surfaces from cross‐section curves has wide applications including bio‐medical modeling. Previous work in this area mostly focused on connecting simple closed parallel cross‐sections. Here we consider the more general problem where input data may lie non‐parallel cross‐sections and consist of curve networks that represent segmentation underlying object by different material or tissue types (e.g., skin, muscle, bone, etc.) each cross‐section. The desired output is a surface...
In the analysis of histopathological images, both holistic (e.g., architecture features) and local appearance features demonstrate excellent performance, while their accuracy may vary dramatically when providing different inputs. This motivates us to investigate how fuse results from these enhance accuracy. Particularly, we employ content-based image retrieval approaches discover morphologically relevant images for image-guided diagnosis, using features, which are generated cell detection by...
We propose a new method for reconstructing an implicit surface from un-oriented point set. While existing methods often involve non-trivial heuristics and require additional constraints, such as normals or labelled points, we introduce direct definition of the function points solution to constrained quadratic optimization problem. The has number appealing features: it uses single parameter (parameter-free exact interpolation), applies any dimensions, commutes with similarity transformations,...
Brocade orange peels (BOPs), typically treated as discardable residue, contain large amounts of bioactive phenols that can serve ingredients for value-added products with health-promoting effects. Given this, this study developed a response surface model to optimize the conditions ultrasound-assisted extraction (UAE). The total phenol and flavonoid contents (TPC, TFC), profiles, antioxidant activities peel extracts free, esterified, glycosylated-bound (FPs, EBPs, GBPs) served metrics...

Abstract The ability to quickly and intuitively edit digital contents has become increasingly important in our everyday life. We propose a novel method for propagating sparse set of user edits (e.g., changes color, brightness, contrast, etc.) expressed as casual strokes nearby regions an image or video with similar appearances. Existing methods propagation are typically based on optimization, whose computational cost can be prohibitive large inputs. re‐formulate function interpolation...
We present a new method for interpolating both boundary values and gradients over 2D polygonal domain. Despite various previous efforts, it remains challenging to define closed-form interpolant that produces natural-looking functions while allowing flexible control of constraints. Our builds on an existing transfinite continuous domain, which in turn extends the classical mean value interpolant. re-derive from property biharmonic functions, prove indeed matches gradient constraints when is...
Summary Inflorescence architecture in plants is often complex and challenging to quantify, particularly for inflorescences of cereal grasses. Methods capturing inflorescence analyzing the resulting data are limited a few easily captured parameters that may miss rich underlying diversity. Here, we apply X‐ray computed tomography combined with detailed morphometrics, offering new imaging computational tools analyze three‐dimensional architecture. To show power this approach, focus on panicles...
Character skinning determines how the shape of surface geometry changes as a function pose underlying skeleton. In this paper we describe templates, which define common deformation behaviors for joint types. This abstraction allows solutions to be shared and reused, they allow user quickly explore many possible alternatives behavior character. The templates are implemented using cage-based deformations, offer flexible design space within develop reusable behaviors. We demonstrate interactive...

Dual contouring (DC) is a feature-preserving isosurfacing method that extracts crack-free surfaces from both uniform and adaptive octree grids. We present an extension of DC further guarantees the mesh generated manifold even under simplification. Our main contribution octree-based topology-preserving vertex-clustering algorithm for contouring. The contoured surface by our contains only vertices edges, preserves sharp features, possesses much better adaptivity than those other methods...
