Inpainting is the method by means of which we can fill the bemused areas of an image. To recreate the bemused areas in a visually probable way is the main end of image inpainting methods. There have been so many algorithms are presented for the same. Two types of methods are available in the market. We had made some advances in Exemplar based inpainting technique to overcome the pitfalls such as computational...
This paper deals with a method of clipping a line segment into a circular window. Its unlike other algorithms, instead of dividing region into segments and generating the corresponding region codes, yields results based their parametric equations which not only yields precise result for each pixel but also compute faster. Its an algorithm that can be embedded in many circular displays in order to...
We report on a vision sensor architecture relying on a pixel-embedded memristive device to perform dynamic background subtraction as basic image processing components, aimed at detecting anomalous events in the scene. A Light-To-Frequency Converter generates digital pulses, which are linearly proportional with the light intensity. During the exposure time, a certain number of pulses, with proper width...
The most commonly used pixel structure in Integrated Circuit (IC) technologies is the three-transistor pixel structure (3T). This structure consists of a pixel, a reset transistor, as source follower and a pixel select transistor. It has been shown that this structure exhibits the best performance and reliability, although no real in-depth analysis has been previously presented. In this paper, a thorough...
This paper presents a model of monitoring method in videos and imagines. In the case of a fixed camera, when moving object appears, all data indicating object movement will change greatly. The real moving target will be detected after processing the data which larger change. The accuracy and instantaneity of will be tested by MATLAB stimulation.
This paper proposes an image clustering algorithm using Particle Swarm Optimization (PSO) with two improved fitness functions. The PSO clustering algorithm can be used to find centroids of a user specified number of clusters. Two new fitness functions are proposed in this paper. The PSO-based image clustering algorithm with the proposed fitness functions is compared to the K-means clustering. Experimental...
An easy way to achieve higher depth of field in a camera-laser configuration is to tilt the image sensor respect to the lens plane, such that the image plane, laser plane and the lens plane intersect in a unique line (Scheimpflug condition [1]). If something has to be measured with this kind of cameras, a proper camera calibration must be done. The usual calibration methods are not valid in this case...
This paper proposes a semantic inference approach, which utilizes a group of context-sensitive Bayesian networks to infer the semantic concepts based on different regional spatial relationships, i.e. disjoined, bordering, invaded by, surrounded by, near, far, right, left, above and below. Each Bayesian network performs the inference based on one kind of the regional spatial relationships. Finally,...
According to SAR image side-look geometry principle, this paper discussed the geometry co-registration, coherence coarse co-registration and coherence matrix over-sample fine co-registration. The accuracy is from low to high. In the end, the experiment was carried out using the SAR image pair that was collected by ERS-1/2, and the result was correct.
This paper presents a method for moving objects tracking in complicated areas based on features fusion and mean shift algorithm. Primary mean shift algorithm is only based on colour feature, and has a suitable performance especially in partial occlusions. However, primary mean shift algorithm would fail to track in some conditions. This paper exhibits a method to solve mean shift algorithm problems...
Shot boundary detection is a field of research of video processing. It aims to automatically detect the transition between the shots in the digital video. In this paper, a new video cut transition detection algorithm is presented by using Hilbert transform and Gray level co-occurrence matrix (GLCM). Texture features are extracted from the GLCM and the corresponding distance measure between the adjacent...
Fisheye cameras are widely used in various applications like surveillance, robotic vision, automobile rear-view imaging systems etc. But the images captured by fisheye lens are hemispherical and objects away from the center of image look curved due to lens distortion. Hence it is a challenge for an end user to interpret the data correctly from these images. The solution lies in digitally processing...
Population is always regarded as one of the most important driving forces of LUCC. Based on the needs of research on driving force of LUCC, impact factors of population distribution, land use system and registered permanent residence system of China, environmental limitation law of the minimum and theories of agricultural location, according to the idea of modeling separately by town and country,...
In this paper, we propose a region-based MRF model with optimized initial regions (RMRF-OIR) for image segmentation. In the RMRF-OIR, a modified mean shift is introduced to get the optimized initial over segmented regions. Then, a region-based MRF is used to model these initial regions on the region adjacency graph. Finally, the segmentation results will be obtained by using a region merging scheme...
This paper using C correction models and methods of study area of ETM images in 2003 ArcInfo software, under the support of map algebra language by using three groups of different resolution levels of the same area of DEM remote sensing images terrain correction. The results show that equals image resolution of remote sensing image for terrain correction when the best effect. This study will for us...
Location-based services are widely used in the Internet services. The method of location cloaking is used to effectively protect the user's location privacy. The current cloaking algorithm does not take into account the regional characteristics, such as population density, popularity level and so on, based on which an attacker can often infer user's exact location from their cloaking area. In this...
Subtractive crosstalk cancelation is an effective way to reduce the appearance of ghosting in 3D displays. However, effective cancelation requires the black level of the input images to be raised above zero, which reduces the image contrast and visual quality. Previous methods for selecting the raised black level do not consider the image content; they are either based on the worst case or they do...
A kind of overlapping effect called bowtie effect occurs around the edge of the scanning swath for optical-mechanical scanner as long as sensors which have swaths wider than one pixel, which aggravates its degree exponentially toward the swath edge. In order to remove bowtie effect, three main factors (satellite motion, earth rotation, scanner mirror) that affect the scanning image are analyzed firstly...
This paper aims to find out how ICT product upgrades influence customer satisfaction. It introduces a common method by which the Quarter Model is used to divide ICT product attributes into four sectors that will be treated differently, and then multiple linear regression model is utilized to analyze how much those attribute changes influence customer satisfaction. An empirical study on cell phone...
While the depth maps of 3D video are represented as luminance images, they are used to aid rendering of novel views and are not viewed by an end user. Therefore, metrics that measure the quality of images that are for end user viewing does not necessarily reflect the quality of depth maps in terms of its ability to render views. This paper investigates the relationship between the quality of the rendered...
