Integrate template matching and statistical modeling for continuous speech recognition
… dissertation, a novel approach of integrating template matching with statistical modeling is proposed to improve continuous speech recognition. Commonly used Hidden Markov Models (HMMs) are ineffective in modeling details of speech temporal evolutions, which can be overcome by template-based …

Assertiveness in boys: evaluating the construct using template matching procedures
The present investigation expanded on the template matching approach (Cone, 1980) to empirically evaluate whether assertiveness is associated with interpersonal success among a group of fourth grade boys. Using popular sociometric status as an index of success in interaction, the performances of 15 …

VIDEO TEMPLATE MATCHING ALGORITHM FOR CONSTRUCTION PROJECTS---A HADAMARD DOMAIN APPROACH
… Of all techniques in real-time video processing, template-matching plays the most essential role because of its high computational complexity and its ability to deal with considerable redundancy. However, commonly used template-matching techniques in spatial domain cannot meet all of the …

QT variability calculation using a template matching algorithm and power spectral analysis
… published in 2003. The algorithm stretches the template in the time domain, and composes a sum-squared error function, which is minimized to find the scaling factor for that beat. These scaling factors are compiled into an array, and an interpolated signal is generated of QT interval times. …

G A N mask R-CNN : instance semantic segmentation benefits from generative adversarial networks
… mask and the ground truth mask -a template matching mechanism. However, any such instance segmentation ConvNet is a generator, so we can lay the problem of predicting masks as a GANs game framework: We can think the ground truth mask is drawn from the true distribution, and a …

Algorithms for Gait-Based Human Identification from a Monocular Video Sequence
… individuals performing the same task and a template-matching approach is suitable for such problems. In situations where the amount of training data is limited, we show the utility of a simple feature viz. the width of the outer contour of the binarized silhouette of the subject and its …

Computer aided diagnosis of miliary TB in chest X-rays
… miliary TB. Some statistical approaches and template matching methods were used to measure characteristics of both healthy and unhealthy (miliary TB) lung textures. These measurements were evaluated to see if a computer can be programmed to differentiate between lung texture from a healthy …

Image processing in echography and MRI
… For left ventricle detection, template matching was used. Forvortex detection,<br/>a data processing framework is presented that consists of three main steps: restoration,<br/>abstraction and tracking. This thesis addresses the first two problems, implementing<br/>restoration …

New positioning system for the CSL Robotics Laboratory Testbed
… techniques for position markers, following a template matching approach. Two modes of operation are implemented, Barycentric and Change of Axes. The new system is able to calculate position using the two methods, and 90% or more of the data points collected in each set lie within 0.05 units …

Form processing with the Hough transform
… to identify the form type based on feature matching. The derived features are rotation, translation and scale invariant. The proposed form description is compact, thereby allows for fast identification. The registration is feature/knowledge based. Two methods for control points detection are …

Human face modeling, analysis and synthesis
… is discussed in detail in this thesis. Based on template matching, the face area and the key points around each facial feature can be determined accurately on the front and side profile view face images. Then a realistic face model of a particular person can be created by mapping a generic 3-D …

Caracterización de sismicidad intraplaca de profundidad intermedia en la zona de subducción chilena
… utilizan los procesos de inversión cinemática y Template Matching. En la inversión cinemática se usan los registros de velocidad para caracterizar la fuente sísmica y se modela el proceso de ruptura mediante un parche elíptico. A partir de esto se obtienen los valores de stress drop que se …

Real-Time Implementation of Vision Algorithm for Control, Stabilization, and Target Tracking for a Hovering Micro-UAV
… implemented include a Harris feature detector, template matching feature correlator, RANSAC similarity-constrained homography, color segmentation, radial distortion correction, and an extended Kalman filter with a standard-deviation outlier rejection technique (SORT). This implementation was …

Variation resolutions for CMOS sensing networks
… with other techniques including high-Q impedance matching for input voltage boosting and hierarchical tandem stages for further improvement on operating conditions. With a Q=10 matching network, -27 dBm sensitivity and 22% efficiency can be achieved for about 0.5 V DC output to a 500 kΩ load at …

Automatic Detection of Elongated Objects in X-Ray Images of Luggage
… on both UNIX and PC platforms. A variety of template matching techniques were evaluated, and the filtering parameters (template size, template model, thresholding value, etc.) were optimized. A variation of matched filtering was found to be reasonably effective, while a Gabor-filtering method …

Feature extraction via heat flow analogy
… techniques are active contours, region growing, template matching and the Hough transform.<br/><br/>In this thesis, we investigate the heat flow analogy, which is a physics based analogy, both for low-level and high-level feature extraction. Three different contributions to feature extraction, …

Methods to improve the signal quality of corrupted multi-parameter physiological signals
… most signicant aspects of the signals. We use template matching to jointly segment the multi-parameter signal, morphological dissimilarity to estimate the quality of the signal segment, similarity search to nd the closest match from a database of templates, and time-warping to reconstruct the …

Methods for optimization of the signature-based radiation scanning approach for detection of nitrogen-rich explosives
… at standoff distances. This technique uses a template-matching procedure that produces a figure-of-merit (FOM) whose value is used to distinguish between inert and explosive materials. The present study develops a tiered-filter implementation of the signature-based radiation scanning …
