This paper describes an objective and subjective evaluation models of pencil still drawings for art education. In the subjective evaluation, the evaluation word is summarized. This is a point of view when an art educator evaluates a pencil still drawing. The objective evaluation model consists of factor Fi, which comprises the features value of a basic pencil still drawing. Fi is also defined by considering...
Videos taken in the wild sometimes contain unexpected rain streaks, which brings difficulty in subsequent video processing tasks. Rain streak removal in a video (RSRV) is thus an important issue and has been attracting much attention in computer vision. Different from previous RSRV methods formulating rain streaks as a deterministic message, this work first encodes the rains in a stochastic manner,...
Signal quality analysis is an important way to ensure high quality of navigation service. Traditional signal time domain evaluation method cannot obtain the detail of signal waveform. This paper uses a method based on the chip measurements to solve this problem. At the same time, this paper proposes an algorithm to evaluate signal quality by using the chip measurement. Finally, this algorithm is used...
Part-based trackers are effective in exploiting local details of the target object for robust tracking. In contrast to most existing part-based methods that divide all kinds of target objects into a number of fixed rectangular patches, in this paper, we propose a novel framework in which a set of deformable patches dynamically collaborate on tracking of non-rigid objects. In particular, we proposed...
Two types of information exist in a stereo pair: correlation (matching) and decorrelation (half-occlusion). Vision science has shown that both types of information are used in the visual cortex, and that people can perceive depth even when correlation cues are absent or very weak, a capability that remains absent from most computational stereo systems. As a step toward stereo algorithms that are more...
Analysis of electrocardiogram and heart rate provides useful information about health condition of a patient. The North Sea Bicycle Race is an annual competition in Norway. Examination of ECG recordings collected from participants of this race may allow defining and evaluating the relationship between physical endurance exercises and heart electrophysiology. Parameters reflecting potentially alarming...
This paper describes an objective evaluation model for pencil still drawing images focused on the composition. The evaluation model consists of factor Fi which is defined as to cover the features value of the basic pencil still drawing image. Fi is also defined by considering a feature of subjective evaluation for the drawn pencil still drawing image. Our model approximate the features of the drawing...
In statistical approaches such as statistical static timing analysis, the distribution of the maximum (or the minimum) of plural distributions is needed, and is computed by repeating a statistical maximum operation of two distributions (2Max operation). Since each distribution is represented by a linear combination of several explanatory random variables (RVs) so as to handle correlations efficiently,...
Subharmonic aided pressure estimation (SHAPE) uses ultrasound contrast agents (UCAs) to estimate hydrostatic pressure by transmitting at one frequency, receiving at its subharmonic frequency and then monitoring the subharmonic amplitude variations. The subharmonic response of the UCAs has an inverse linear relationship with the ambient pressure. In order to optimize SHAPE, we studied the impact of...
A novel procedure to determine foot shape is propose. The relationship between shape features is used to discriminate shape. Five foot shape features that are Left Foot Length (LFL), Left Foot Breadth (LFB), Left Ball Girth Circumference (LBGC), Left Instep Length (LIL) and Left Fibulare Instep Length (LFIL) from a random sample of 161 Malaysians ladies were studied. Two groups of foot shape feature...
To aid in the real-time monitoring of system stability, it is useful to assess the relative damping of an underlying impulse response from noisy, ambient data. This is typically done using modal decomposition, procedures that accurately and consistently estimate natural frequencies of oscillation but struggle with estimates of damping. Here we introduce a measure of “persistence” as a robust measure...
The performance of a rotating stirrer made of helically positioned paddles is experimentally analyzed. The statistically independent positions are computed as a function of the number of paddles, paddle separation and relative tilt angle. With respect to a traditional single paddle wheel stirrer, the structure combines a helical path and just a simple engine required for the rotation. The analysis...
In this work, we explore the problem of generating fantastic special-effects for the typography. It is quite challenging due to the model diversities to illustrate varied text effects for different characters. To address this issue, our key idea is to exploit the analytics on the high regularity of the spatial distribution for text effects to guide the synthesis process. Specifically, we characterize...
We present a data-driven inference method that can synthesize a photorealistic texture map of a complete 3D face model given a partial 2D view of a person in the wild. After an initial estimation of shape and low-frequency albedo, we compute a high-frequency partial texture map, without the shading component, of the visible face area. To extract the fine appearance details from this incomplete input,...
Oil spills and lookalikes (e.g. plant oil and oil emulsion) show the dark areas in SAR images, so it will bring some difficult in classifying the dark objects observed in full polarization SAR images into oil spills or lookalikes. In this paper, an approach is presented for distinguishing the dark areas in SAR images, which based on polarization features, geometric features and texture features fusion...
In this paper, we propose a persistent scatterer clustering method for high-resolution structure displacement analysis. Persistent scatterer interferometry can monitor millimetric displacement of structures like bridges, buildings, and roads by analysis at persistent scatterers (PSs), pixels with high coherence in synthetic aperture radar (SAR) images. However, it requires great time and effort to...
Facial analysis plays very important role in many vision applications, such as authentication and entertainments. The very early works in the 1990s mostly focus on estimating geometric deformations of facial landmarks to address this task. While in the past several years, more and more efforts have been made to directly learn an appearance regression for facial analysis. Though training regressions...
Controlling the output beam of a multimode fiber (MMF) is quite a hot topic currently because it offers several attractive perspectives. Among the various technics used to shape the output beam of a multimode fiber, the adaptive approaches rely on a measurement (objective function) which feeds an algorithm for further command of a spatial modulator for optimization. This approach gives several advantages:...
Statistical craniofacial reconstruction methods have become an important research aspect in computer-aided craniofacial reconstruction. The existing joint statistical craniofacial reconstruction method based on PCA modeling is not scientific in terms of forensic anthropology, and its description ability for the shape correlation of skull and face is inadequate. So, partial least squares regression...
According to the influence of the stand spatial structure on the crown shape of Chinese fir, a new method of diversified 3D Chinese fir modeling based on spatial structure was proposed. In this study, spatial structure units that were divided by a reasonable method were selected in Chinese fir stands. And the data of spatial structure and crown shape in different units was surveyed. Two parameters...
