Accurate assessment of the orientation of the pelvis on the operating table is a crucial step for a number of surgical procedures in orthopaedics. The anterior pelvic plane (APP) has been traditionally used as a reference in various pelvic surgeries including a number of trauma, reconstruction and arthroplasty applications. The APP is either manually traced by over the skin palpation in convent...

We have used a direct imaging technique, in situ atomic force microscopy (AFM), to observe the dissolution of the basal biotite surface by oxalic acid over a range of temperatures close to ambient conditions, using a specially designed AFM liquid cell and non-invasive intermittent contact mode of operation. From the 3-dimensional nanometre-resolution data sets, we observe a process characterise...

Definition is one of the most important parameters of the color image quality and is determined by the resolution of channel brightness and chromaticity. System resolution is traditionally determined by a number of the television lines, calculated on the maximal spatial frequency value at which threshold contrast of the reproduced image is provided. Traditional methods of definition analysis ar...

This study was designed to identify surface and subsurface microscopic changes in different carious lesions by using Confocal Laser Scanning Microscope (CLSM) and Image analyzer (light microscopy). Thirty extracted carious posterior teeth were fixed, embedded and polymerized in plastic fixation medium. The final thin sections (80mm) were stained with H&E and Masson Goldner's Tricome while other...

Deep Cervical Flexor (DCF) muscles are important in monitoring and controlling neck pain. While ultrasonographic analysis is useful in this area, it has intrinsic subjectivity problem. In this paper, we propose automatic DCF extractor/analyzer software based on computer vision. One of the major difficulties in developing such an automatic analyzer is to detect important organs and their boundar...

Differential diagnostics of borderline ovarian tumours and ovarian carcinomas is generally based on morphological criteria, which are not always sufficient for final diagnosis. Therefore, we investigated the practical diagnostic application of the CAS200 image analyzer and new ploidy-related parameters in a series of 68 borderline tumours and 42 low-grade carcinomas of the ovary. Highly signifi...

A new video coding approach based on texture analysis and synthesis is presented. The underlying assumption of our approach is that the textures in a video scene can be labeled subjectively relevant or irrelevant. Relevant textures are defined as containing subjectively meaningful details, while irrelevant textures can be seen as image content with less important subjective details. We apply th...
