The authors proposed the texture unit-based texture spectrum approach in 1990, which has been used for texture analysis, including texture characterization, texture classification, texture edge detection, and textural filtering. One of the most important disadvantages related to this method is the large number of texture units (6,561) and its redundancy. This paper aims at simplifying the origi...

BACKGROUND The purpose of this research is to compare the clinical results of different drainage methods in total knee arthroplasty (TKA). METHODS This retrospective comparative study included 55 patients who accepted primary unilateral TKA between October 2010 and November 2012. The patients were classified according to the drainage method used: 25 patients in the autotransfusion drainage gr...

Texture is one of the fundamental image characteristics useful in computer vision tasks such as object recognition and scene analysis. Texture segmentation is one of the image analysis tasks. The prospect of texture segmentation depends on the choice of the texture description method and the segmentation procedure. In this paper, color-texture descriptors are proposed to represent the texture c...

Procedural textures usually require spending time testing parameters to realize the diversity of appearances. This paper introduces the idea of a procedural texture preview: A single static image summarizing in a limited pixel space the appearances produced by a given procedure. Unlike grids of thumbnails our previews present a continuous image of appearances, analog to a map. The main challeng...

OBJECTIVE To evaluate the need for post-pneumonectomy thoracic drainage. METHODS This was a retrospective study of 46 patients having undergone pneumonectomy in the Thoracic Surgery Department of the Londrina University Hospital between January of 1998 and December of 2004. Patients were divided into two groups: those having been submitted to drainage and those not having been. The diseases i...

Level-of-detail modeling is a vital representation for real-time applications. To support texture mapping progressive meshes (PM), we usually allow the whole PM sequence to share a common texture map. Although such a common texture map can be derived by using appropriate mesh parameterizations that consider the minimization of geometry stretch, texture stretch, or even the texture deviation int...

BACKGROUND Liver surgery in perihilar cholangiocarcinoma (PHC) is associated with high postoperative morbidity because the tumor typically causes biliary obstruction. Preoperative biliary drainage is used to create a safer environment prior to liver surgery, but biliary drainage may be harmful when severe drainage-related complications deteriorate the patients' condition or increase the risk of...

It is a unique approach for steganography using a reversible texture synthesis where rather than using existing image the algorithm will create new texture image using source texture and embeds message by texture synthesis process. The new image with similar appearance can be re-created by using texture synthesis process. The size of new image can be user specified. The important concept behind...

abstract one of the ways to increase economic and environmental efficiency of drainage systems is water table management. water table management consists of, controlled drainage and subirrigation. this study examines the effect of controlled drainage on yield, root distribution pattern and water use efficiency of maize (sc 704) in karaj. the experiment was performed as a randomized complete des...
