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.
The issue of temporal and spatial variation in soil salinity is considered as a fundamental element in salinity monitoring. The aim of this study is to develop a framework which integrates image mining techniques with Fuzzy logic methodology to improve the evaluation of spatio-temporal variation of soil salinity in areas with lack of available ground observation. Intensity and duration of salinity...
Data acquisition and storage is an important step in the process in building GIS system. In the process of building a database, using the method of intelligent automatic vectorization is of great significance for reducing the workload of building a database and improving working efficiency. This paper presents a method of point pattern recognition based on interactive approach, that is to say, the...
In order to improve and enforce environmental monitoring ability, especially in fields of large scale monitoring and dynamic monitoring, the Environmental Satellite will be launched in 2008 in China. Before the Satellite is launched, necessary pre-research work has to be done. Considering future ecological monitoring demand, we have paid more attention to land use/land cover classification method...
Research on remote sensing monitoring methods of crop planting area is always the hot topic, and theories and methods about single-crop rice emerge one after another. However, in terms of the practice, there are no fixed methods or schemes yet. This paper puts some methods of planting area extracting into practice, and compares their merits and faults in precision and efficiency. The result shows...
There is higher vegetation cover in southern China, So, the smaller altered target, the smaller scale remote sensing data and other negative factors affect the mapping precision of clay alteration minerals. However, the clay alteration is closely re elated to the uranium mineralization. To extract the clay alteration information in vegetation coverage, The paper chooses the uranium ore field of Tao...
It is difficult to distill vector data from thematic map automatically and accurately because of disturb information. Therefore, an algorithm named Neighborhood Filling is discussed here to separate disturb information from thematic map. On the basis of distinction between disturb information and the interference background information. Set some background information on the priority. Use principle...
Road detection from satellite images can be considered as a classification process in which pixels are divided into road and background classes and can be used as a criterion in road extraction process to discriminate between road and non road pixels. Apart from the spectral information, textural parameters and contextual information are usually used by human being in object recognition from images...
To better protect the security of information, this paper proposed an information transmission scheme which combined the cryptosystem and information hiding. The scheme pretreated the information firstly by making use of the RSA arithmetic which belongs to the public key cryptosystem, and then took advantage of the improved LSB which based on the Human Visual System to make the cryptograph hid in...
For medical treatments, the integrity of the medical images, the authenticity of corresponding medical records, and the privacy of the patients are crucial requirements for the diagnosis of patient's disease. Therefore, how to retain the validity between images and medical records is an important topic for researches and real applications. In this paper, we apply the concept and implementation in...
The classification of remotely sensed images knows a large progress seen the availability of images of different resolutions as well as the abundance of the techniques of classification. Moreover a number of works showed promising results by the fusion of spatial and spectral information. For this purpose we propose a methodology allowing to combine this two information to refine an SVM classification,...
Automated learning systems used to extract useful information from musical scripts, play a major role in optical music recognition. Optical music recognition or OMR has been widely used to extract the musical notations and knowledge from old scripts and thus enclose lot of importance in retrieving historical data. The field of pattern recognition and knowledge representation has to be symmetrically...
It is a common experience to the web users with the existing search engines like Google, Yahoo, MSN, Ask, e.t.c., that the information related to the entered query returns a long ranked list of results (snippets). It becomes cumbersome to the user to go through each title, snippet and even sometimes link of the search results until relevant results are found to the query. Clustering of search results...
A Printed photograph cannot be used to recover the original digital image with improved accuracy because of distortions introduced during the process of scanning the printed material. This paper describes a method to recover the original digital images from the print-scan channel with improved quality. We solve this approximation problem by formulating a method for approximating the original digital...
Histologic analysis of a stained tissue sample by a trained pathologist forms the definitive diagnosis of prostate cancer. Rapid and objective second opinions are highly desirable to make more accurate diagnostic decisions. One alternate method is to use Fourier transform infrared (FT-IR) spectroscopic imaging, which is an emerging technique that combines the molecular selectivity of spectroscopy...
A beading design diagram reading system was implemented for supporting handicraft by visually impaired persons. Beading is one of popular handicraft done by visually disabled persons as a recreational activity. However, it is not possible for them to watch symbols on design diagram. Sighted volunteers read diagrams for them but the work is hard and it takes several days to convert patterns to texts...
In this paper we are proposing to detect the localization and recognition of an indoor stairway. This is a fundamental step in the implementing of autonomous stair climbing navigation, as well as the implementing of passive alarm systems intended for the blind and visually impaired. Both of these systems must be able to recognize parameters that can describe stairways in unknown environments. This...
Video completion is used for repairing damaged or missing data in a video sequence. This paper proposes a video completion method using robust motion estimation and color compensation. The proposed method consists of three steps: motion estimation, source patch search, and color assignment. If an input video contains brightness change, existing video completion methods give poor results. For overcoming...
In multiple moving object detection, the connection between objects and shadow always leads to the failure of object detection. To solve this problem, a new object extraction algorithm using level set is proposed and applied to detect moving vehicle in intelligent monitoring of motorway. Moving information is extracted via symmetrical difference and used in the velocity function of level set. After...
A reversible data hiding technique with high capacity of data embedding is presented in this paper. Using both difference expansion and histogram shifting methods at the same time we have improved Luo et al.'s method to increase the amount of data that can be embedded into the host image. First the image is examined for possible overflow/underflow problem that might occur during embedding; then if...
