Texture synthesis aims to define and reproduce discriminating image features. These features are used to associate with and differentiate between two textures. Often texture is composed of a pattern with an element of randomness in each feature’s appearance, position and orientation. The goal is to imitate the sample texture in such a way that sample and synthesised texture are perceived to be ...

Measured material representations like Bidirectional Texture Functions or Reflectance Fields offer very realistic appearance but the user is currently not capable of changing this appearance in an effective and intuitive way. Such editing operations would require a low-dimensional but expressive model for appearance that exposes only a small set of intuitively editable parameters (1D-sliders, 2...

image compression, texture mapping, 3D graphics, JPEG, JPEG-LS, polynomial texture maps Polynomial Texture Maps (PTM's) are representations of stationary 3D objects which provide enhanced image quality and improved perception of the object surface details at the cost of increased storage requirements. In this paper, we investigate several compression schemes for PTM's, that either preserve ever...

In this thesis, we present a texture synthesis method for realistic rendering without acquiring the actual reflectance properties. The method is from the observation that most objects have texture repeatedly laid on different locations of their surface explicitly or implicitly. These samples form a pretty sparse set of BTFs. Our goal is to extract the underlying texture from photographs of the ...

now days, citizens safety in urban spaces is one of the most important worries of urban managers. this may be reflected in different characters of urban spaces such as physical, social and economical and even political characters. with regard to increasing crimes and complexities of urban spaces, trying for achieve to sustainable, healthy and good cities mean in providing the safety environment...

BACKGROUND Swallowing is triggered when a food bolus being prepared by mastication has reached a defined state. However, although this view is consensual and well supported, the physical properties of the swallowable bolus have been under-researched. We tested the hypothesis that measuring bolus physical changes during the masticatory sequence to deglutition would reveal the bolus properties po...

The use of 3D laser scanner in documenting heritage sites has increased significantely over the past few years. This is maily due to advances of such systems which allow for the fast and reliable generation of millions of 3D points. Despite the considerable progress of these approaches, the highest possible degree in efficiency and flexibility of data collection will be possible, if other techn...
