Computer Analysis of Regular Repetitive Textures
Regular rcpttitive texam arc common in rcal-workl scaux, occurring in both n a n d and man-made environments. Their analysis is important for image segmentatim and fos shape recovery from surf= texture. There are two fundamental problems in analyzing reguiar repetitive texture. F d y , rbc frcsucncy interpretation of any regular t e x m is ambiguous since that arc many altanative imqmatiap tbat...
متن کاملProgrammable Generation of 2D Vector Textures
For a long time, artists and technical illustrators have used textures made of small 2D elements, arranged in a repetitive fashion. These textures have been widely used to produce pictures. Today, the diffusion of high resolution color wide printers and digital looms creates a need for very large digital pictures. However, producing textures by hand is a slow and tedious process. That’s why the...
متن کاملEfficient Generation of Soft Shadow Textures
Soft shadows give important cues of realism to 3D scenes. Existing methods can produce hard shadows in real time and soft shadows in minutes to hours per frame. Here a technique for producing accurate soft shadows quickly in software is presented, allowing soft shadow texture maps to be computed for simple scenes on commodity hardware in real time.
متن کاملPractical generation of video textures the auto-regressive process
Recently, there have been several attempts at creating ‘video textures’, that is, synthesising new (potentially infinitely long) video clips based on existing ones. One method for achieving this is to transform each frame of the video into an eigenspace using Principal Components Analysis so that the original sequence can be viewed as a signature through a low-dimensional space. A new sequence ...
متن کاملAutomated Generation of Building Textures from Infrared Image Sequences
In this paper the application of computer graphics and computer vision for texture extraction from infrared image sequences is described. These techniques normally are used in computer graphics to project a virtual scene onto the image plane. For the matching between the images and the given 3D model a strategy is presented based on the estimation of planes in the image sequence using homograph...
