AIM The purpose of this study was to retrospectively evaluate the efficacy of the developed by the authors surgical technique in patients with a radiographically confirmed diagnosis of sagittal craniosynostosis. MATERIAL AND METHODS 34 children with scaphocephaly underwent surgical treatment with the authors' operative technique. Quantitative assessments of the operative results, based on the...

It is proposed to use irregularity, the scale invariant index based on the ideas of fractal geometry to assess the spatial features of font drawings. The index is sensitive to the shape of characters in the font, which affects text legibility. Preliminary results have shown promising application of the proposed index for classifying fonts by reading speeds.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main source(s): University Groningen/University Medical Center Groningen. Background Left ventricular (LV) remodelling has been described as the pathway that precedes heart failure. This process consists changes in shape, size, volume and function left ventricle; all this directly associated to increased risk majo...

In a curved surface design, the overall shape features that emerge from combinations of shape elements are important. However, controlling the features of the overall shape in curved profiles is difficult using conventional microscopic shape information such as dimension. Herein two types of macroscopic shape information, curvature entropy and quadrature curvature entropy, quantitatively repres...

To characterise the relation between pharyngeal anatomy and sleep related disordered breathing, 17 men with complaints of snoring were studied by all night polysomnography. Ten of them had obstructive sleep apnoea (mean (SD) apnoea-hypopnoea index 56.3 (41.7), age 52 (10) years, body mass index 31.4 (5.3) kg/m2); whereas seven were simple snorers (apnoea-hypopnoea index 6.7 (4.6), age 40 (17) y...

Local solid shape applies to the surface curvature of small surface patches-essentially regions of approximately constant curvatures-of volumetric objects that are smooth volumetric regions in Euclidean 3-space. This should be distinguished from local shape in pictorial space. The difference is categorical. Although local solid shape has naturally been explored in haptics, results in vision are...

Shape matching or recognition is computation intensity work in shape analysis. Paper [3] proposed an efficient shape matching method using shape contexts (SC). In this project, wavelet transform is used to scale or compress images into much smaller sizes and then shape context algorithm is used to match shapes. Simulation results show that the matching speed is faster and matching results are m...

Similarity-based retrieval from databases of isolated visual shapes has become an important information retrieval problem. The goal of the current work is to achieve high retrieval speed with reasonable retrieval effectiveness, and support for partial and occluded shape queries. In the proposed method, histograms of local shape parts are coded as index vectors. To increase retrieval accuracy, a...

background and aim: horseshoe placenta is a variant of ring-shaped placenta. ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. this report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...
