Transferring artistic styles onto everyday photographs has become an extremely popular task in both academia and industry. Recently, offline training has replaced online iterative optimization, enabling nearly real-time stylization. When those stylization networks are applied directly to high-resolution images, however, the style of localized regions often appears less similar to the desired artistic...
Underwater images always suffer from low visibility and color distortion because of exponential attenuation along with scattering caused by the water property. In order to get a precise vision of the underwater environment, an underwater image fusion method is proposed in this paper. We use dark channel prior theory and histogram equalization to get a set of optimal images from the input images, and...
Referrals play an essential role in the healthcare system. It has been shown that 60%~70% patients visiting hospitals are referrals. The Centers for Medicare and Medicaid (CMS) has released a large scale physician referral data set, which enables research on referral networks. Recently, we have developed a data-driven system to investigate referral networks based on the CMS open data. In this paper,...
In this paper, we present an integrated approach of multiple algorithms for visual localization and object tracking. First, a spatial point monocular vision range model is established. Combined with vision technology, we can deduce a precise position of the target in the world frame, and the region of recognized object is regarded as the real tracking region. Second, The Camshift/Kalman/Particle algorithm...
Traditional coded structured light with spatial neighborhood is a well-known technique which is used to acquire 3D information. In this paper, we use stereo structure by adding a camera so that the calibration of projector could be omitted. By projecting a new color stripe pattern in which the thick stripes are encoded of De Bruijn sequences with six different channel values and order three, while...
In this paper, we will illustrate a practice of pipeline process to maximize the parallelization of all possible interference-free relays in the broadcasting of wireless sensor networks (WSNs), in order to optimize the end-to-end delay performance in both the (synchronous) round-based systems and the (asynchronous) duty cycle systems. Broadcasting is one of the fundamental communications in WSNs....
This paper introduces an image fusion technique on a gated image. Gated imaging is a powerful technique to capture images in turbid condition. By controlling the time delay of the shutter to capture the returning light, we can obtain the image at different depth. Modular transfer function (MTF) is used to evaluate the quality of the gated images. Images with useful information (clear and sharp objects)...
At present, coded structured light is considered one of the most reliable techniques for reconstructing the surface of objects. With the rapid development of the industrial test technology , rapid prototyping technology and so on, the three-dimensional object contour surface reconstruction and measurement is widely used, and the higher measuring speed is required, so some real-time three-dimensional...
Event detection is an important research in video surveillance technology. This paper proposed a method for traffic event detection based on visual Mechanism on the background of traffic video surveillance applications. In this method, based on the extraction of video target motion characteristics, it extracted abnormal targets mainly through the features merging and significant competitive in video...
In this paper, a review of visual guidance systemsof autonomous vehicle is presented. The challenges of autonomous navigation in rainforest or tropical terrain are highlighted. There are several methods used in navigation system of the autonomous vehicle and it is shown that vision system remains a key-enabling component for successful navigation system. Color feature is used to examine the general...
Images captured under bad weather conditions usually have poor contrasts and colors. Due to the scattering of light, the degradation of an image increases exponentially with the depths of the scene points. Previously implemented methods are limited, because an interactive step was required to select the sky brightness and the vanishing point of the image, as well as the information about the atmospheric...
Blind image quality assessment refers to the problem of evaluating the visual quality of an image without any reference. In this paper, we present a no-reference blur metric for images and video using information contained in the image itself. We look at the sharpness of the sharpest edges in the blurred image, which contains information about the blurring, and is not on the image contents. The experimental...
