Designing realistic tridimensional facial models is a challenging task, not only due to the effort and artistic abilities required but also because human visual perception very tuned processing of features. For this reason, rather than creating face from scratch, artists usually start scanned model real person. In work, we present novel method for blending faces in order create new one. nutshel...

Solid models may be blended through filleting or rounding operations that typically replace the vicinity of concave or convex edges by blends that smoothly connect to the rest of the solid’s boundary. Circular blends, which are popular in manufacturing, are each the subset of a canal surface that bounds the region swept by a ball of constant or varying radius as it rolls on the solid while main...

An important problem at an integrated steel producing plant is the blending of different types of coals to make coke for the blast furnace operation. Historically linear blending models were not appropriate because coal properties important for both optimum cokemaking and blast furnace operation do not combine linearly and are not completely understood. In this talk, a two-step methodology is d...

Implicit modelling is a powerful technique to design geometric shapes, where a geometric object is described by a real function. In general, the real functions used in implicit modelling are unbounded and can take any values in space R. In general, the shapes described by different level sets of an unbounded implicit function can be varied significantly and are very unpredictable. In addition, ...

This paper presents a system for creating a full 360degree panorama from rectilinear images captured from a single nodal position. The solution to the problem is divided into three steps. The rst step registers all overlapping images projectively. A combination of a gradient-based optimization method and a correlationbased linear search is found to be robust even in cases of drastic exposure di...

We propose an implementation of the eight Optimality Principles from the framework of Conceptual Blending, as presented by Fauconnier and Turner (1998). Conceptual Blending explains several cognitive phenomena in the light of the integration of knowledge from different mental spaces onto a single mental space: the Blend. The Optimality Principles express general pressures that compete in the ge...

In this paper the real time virtual dress-up system has been proposed. The proposed system consists of multiple tasks including extraction of different body parts, torso detection, resizing input dress images and dress up using blending and re-blending techniques over the subject. The coexistence of different clothing and cluttering backgrounds is the main difficulty for accurate body extractio...

In this paper, we propose novel GPU accelerated algorithms for interactive point-based rendering (PBR) and high-quality shading of transparent point surfaces. By introducing the concept of deferred blending we are able to formulate the smooth point interpolation problem as an image compositing post-processing task. Consequently, our new PBR algorithm does not suffer from an extra visibilityspla...
