Stereo vision is a well-known technique for acquiring depth information. In this paper, we propose a real-time high-quality stereo vision system in field-programmable gate array (FPGA). Using absolute difference-census cost initialization, cross-based cost aggregation, and semiglobal optimization, the system provides high-quality depth results for high-definition images. This is the first complete...
Stereo vision is a well-known technique for acquiring depth information. In this paper, we present an FPGA-based real-time high-quality stereo vision system. By using AD-Census cost initialization, cross-based aggregation and semi-global optimization, the system provides high-quality depth results for highdefinition images. This is the first complete real-time hardware system that supports both cost...
Heart failure (HF) is a kind of serious cardiovascular diseases, leading to an increasing burden imposed on public healthcare. Early diagnosis and proper treatment of HF are essential to reducing its morbidity and mortality. In spite of the implementation of clinical guidelines for HF, early recognition and stratification of HF risk remain unsolved. In this work, we supposed a computational model...
To help clinicians diagnose Heart failure (HF) at the early stage, this study proposes a scoring model based on support vector machine (SVM). Missing data in clinic are imputed by employing Bayesian principal component analysis. According to the evaluation of cardiac dysfunction, samples are classified into three groups: the healthy group (without cardiac dysfunction), the HF-prone group (in asymptomatic...
A new sub-pixel subdivision location algorithm for estimating the position of the star on the focal plane array is proposed. An analytical study of the optics theoretical point spread functions is presented and it is shown that the star intensity distribution is close to the Gaussian point spread function model. Based on the numerical model of the star, a Gaussian curved fitting algorithm for centroiding...
