In this paper we talk about a new efficient numerical approach to deal with inaccuracy when implementing geometric algorithms. Using various floating-point filters together with arbitrary precision packages, we develop an easy-to-use expression compiler called EXPCOMP. EXPCOMP supports all common operations +,−, ·, /,√ . Applying a new semi-static filter, EXPCOMP combines the speed of static fi...

We introduce a new approach for tracking-based segmentation of 3D tubular structures. The approach is based on a novel combination of a 3D cylindrical intensity model and particle filter tracking. In comparison to earlier work we utilize a 3D intensity model as the measurement model of the particle filter, thus a more realistic 3D appearance model is used that directly represents the image inte...

We introduce new generative semisupervised mixtures with more fine-grained class label generation mechanisms than in previous works. Our models combine advantages of semisupervised mixtures, which achieve label extrapolation over a component, and nearest-neighbor (NN)/nearest-prototype (NP) classification, which achieve accurate classification in the vicinity of labeled samples. We propose seve...

In many person re-identification applications, typically only a small number of labeled image pairs are available for training. To address this serious practical issue, we propose a novel semi-supervised ranking method which makes use of unlabeled data to improve the reidentification performance. It is shown that low density separation or graph propagation assumption is not valid under some con...

This paper presents a 71MS/s oversampling D/A converter for DMT-ADSL applications and focuses on the design and performance analysis of the sigma-delta modulator. Design trade-off among the interpolator, current-mode semi-digital FIR filter and analog continuous-time filter has also been discussed. By optimizing the NTF zeros of the 5-th order modulator with an oversampling ratio of 32, the D/A...

A 33 year old male with no known risk factors for hypercoagulability developed a massive thrombi in the inferior vena cava (IVC). The patient had a history of both pulmonary embolism and embolism related syncope. The thrombus which extended proximally to the level of the renal vein and distally to the left superficial femoral vein did not respond to anticoagulant therapy or thrombolysis. Thirte...

A number of parameters affecting the adsorption of rRNA and poly(A)-containing RNA to Millipore filters were investigated separately. Binding of both types of RNA to the filter was dependent on the concentration of RNA, pH and Mg2+ concentration of the reaction mixture. Both types of RNA bound to the filter optimally at slightly acid pH values. The binding of poly(A)-containing RNA to the filte...

High-speed recursive filter structures for interpolation and decimation with factors of two, and quadrature mirror filter (QMF) banks with perfect magnitude reconstruction, are proposed. The structures are composed of identical all-pass subfilters that are interconnected via extra multipliers. For the case of interpolation and decimation filters, the overall transfer function corresponds in the...

This paper proposes a technique for controlling singing style in the HMM-based singing voice synthesis. A style control technique based on multiple regression HSMM (MRHSMM), which was originally proposed for the HMM-based expressive speech synthesis, is applied to the conventional technique. The idea of pitch adaptive training is introduced into the MRHSMM to improve the modeling accuracy of fu...
