Texto completo

Resumen

This thesis is concerned with single and multiple target visual tracking algorithms and their application in the real world. While they are both powerful and general, one of the main challenges of tracking using particle filter-based algorithms is to manage the particle spread. Too wide a spread leads to dispersal of particles onto clutter, but limited spread may lead to difficulty when fast-moving objects and/or high-speed camera motion throw trackers away from their target(s). This thesis addresses the particle spread management problem. Three novel tracking algorithms are presented, each of

Resumen

This dissertation is focused on developing the new target localization and the target velocity estimation methods for frequency-only multi-input, multi-output (MIMO) radar systems with widely separated antennas. If the frequency resolutions of the transmitted signals are enough, only the received frequencies and the Doppler shifts can be used to find the position of the target. In order to estimate the position and the velocity of the target, most multistatic radars or radar networks use multiple independent measurements from the target such as time-of-arrival (TOA), angle-of-arrival (AOA)

Resumen

From a general point of view, the aim of this thesis is to study the appearance and the translation of the metaphor in a context that involves specialized texts. Our purpose is also to examine the historical expression of metaphor within aspects connected to its importance for creation of scientific terms. More precisely, the main object is to explore how metaphors have been used in the field of medical terminology and by which methods they have been translated across the languages. Our approach is based on the definition of conceptual metaphor conceived by Lakoff & Johnson as a product of

Resumen

Dans de nombreux problèmes du monde réel, les données de formation et les données de test ont des distributions différentes. Cette situation est communément appelée " décalage de l'ensemble de données ". Les paramètres les plus courants pour le décalage des ensembles de données souvent considérés dans la littérature sont le décalage des covariables et le décalage des cibles. Dans cette thèse, nous étudions les modèles nonparamétriques appliqués au scénario de changement d'ensemble de données. Nous développons un nouveau cadre pour accélérer la régression par processus gaussien. En particulier,

Resumen

Recent advances in molecular biology has led to the discovery of many new potential drugs. However, difficulties with in situ analysis of ligand binding prevents quick advancement in clinical trials, which stresses the need for better direct methods. A relatively new methodology, called Cellular Thermal Shift Assay (CETSA), allows for detection of ligand binding in a cells natural environment and can be used in combination with Mass Spectrometry (MS) for readout. With help from the Pelago Bioscience team, I developed a pipeline for processing of CETSA MS data and a web based system for viewing

Resumen

Les séries temporelles de débit des rivières sont établies à l'aide de "courbes de tarage", qui sont des modèles avec les hauteurs d’eau en entrée et les débits en sortie. Malheureusement, de nombreuses stations hydrométriques ont une relation hauteur-débit instable, notamment à cause de l’évolution du lit de la rivière lors des crues. Ces "détarages" posent problème à la fois pour l'établissement des séries hydrologiques de long-terme (analyse rétrospective) et pour la fourniture de données en temps réel, par exemple pour la prévision des inondations, avec des incertitudes quantifiées et fiab

Resumen

This research has been a study in amazement. Initially an agnostic physics graduate, the researcher undertook training in the person-centred approach (pca) to self-development and counselling, during which she came to experience strange personal experiences which she could neither gainsay nor fit into her then worldview. Sketching these briefly, exceptional human experiences (EHEs) and synchronicities increasingly happened until (shockingly) they declared a seeming spirit guide (Mungo) to her, also juxtaposed in time with her first-ever chance encounter with dowsing. Thereafter these phenomena

碩士<br>國立東華大學<br>資訊工程學系<br>94<br>We present a video object tracking algorithm based on a mean-shift algorithm with an adaptive target model that can distinguish a target object from its surrounding background. The target model records a relative likelihood ratio of the feature attributions between the target object and the surrounding background. Moreover, the target model is dynamically updated to reflect the changes of the probability density function of the tracking object. An energy-log-likelihood ratio test is applied to compute the confidences of new features in the video sequence. A segm

碩士<br>元智大學<br>通訊工程學系<br>94<br>In this thesis, an automatic aircraft target recognition (ATR) framework is presented, which is based on the high resolution range profiles (HRRP) of aircraft targets. This work is divided into two major parts. First, we consider the generation of the HRRP, which includes the modeling and simulation of radar cross section (RCS), the design of step frequency waveform (SFW), and IFFT processing for HRRP synthesis. In practice, a possible circular shift of the received HRRP relative to the template HRRPs in target library may exist. In such a situation, we resort to

Resumen

Though deep learning has achieved significant successes in many computer vision tasks, the state-of-the-art approaches rely on the availability of a large amount of labeled data for supervision, collection of which is expensive and time-consuming. Moreover, the performance of these models suffer when there is a mismatch between training and test data distributions. Motivated by this, we design Unsupervised Domain Adaptation (UDA) algorithms that address the distribution shifts without requiring label information in order to adapt to the new environment. In the first part of this work, we show

Resumen

Thanks to its improved capabilities, the Multiple Input Multiple Output (MIMO) radar is attracting the attention of researchers and practitioners alike. Because it transmits orthogonal or partially correlated waveforms, this emerging technology outperformed the phased array radar by providing better parametric identifiability, achieving higher spatial resolution, and designing complex beampatterns. To avoid jamming and enhance the signal to noise ratio, it is often interesting to maximize the transmitted power in a given region of interest and minimize it elsewhere. This problem is known as t

Resumen

碩士<br>國立中興大學<br>資訊科學與工程學系<br>102<br>To avoid the car accident due to vehicle doors opening, we need an anti-collision detection method. Our anti-collision detection method uses “object tracking” on image processing with the video from the camera on the left rear-view mirror of the vehicle. By using object tracking algorithm, we can estimate the position, scale and orientation of the vehicle behind. However, the scale of the target can’t be estimated well when the vehicle comes close to the camera. In this study, a new tracking method is proposed to solve the above problem, it is based on the m

Resumen

Nickel is an essential transition metal for the virulence and survival of Helicobacter pylori in the acidic human stomach. The nickel– and proton– dependent transcriptional regulator HpNikR is important for maintaining nickel homeostasis inside the cytosol by regulating multiple H. pylori genes. A previous ChIP-sequencing experiment with H. pylori G27 and HpNikR identified two novel genes currently annotated as putative iron-transporters, HpG27_866 and HpG27_1499. In vitro DNA-binding assays with the promoter sequences of the two genes revealed nickel-dependent HpNikR binding with an affinity
