Semi-automatic Detection and Enhancement of Linear Features to Update Gis Files
نویسندگان
چکیده
This paper describes a program developed to allow semi-automatic detection and enhancement of linear features in aerial photography. The program employs three different edge detectors namely Sobel, Deriche and Canny as well as morphological operations. The effectiveness of each of these operators and mathematical morphology is compared. Classification accuracy evaluation demonstrated that the Canny edge filter gave best results among these algorithms. The program is able to extract roads, field boundaries, and rivers to update GIS databases.

متن کاملIntegration of Visible Image and LIDAR Altimetric Data for Semi-Automatic Detection and Measuring the Boundari of Features
This paper presents a new method for detecting the features using LiDAR data and visible images. The proposed features detection algorithm has the lowest dependency on region and the type of sensor used for imaging, and about any input LiDAR and image data, including visible bands (red, green and blue) with high spatial resolution, identify features with acceptable accuracy. In the proposed app...

Background: Accurate and early detection of non-alcoholic fatty liver, which is a major cause of chronic diseases is very important and is vital to prevent the complications associated with this disease. Ultrasound of the liver is the most common and widely performed method of diagnosing fatty liver. However, due to the low quality of ultrasound images, the need for an automatic and intelligent...
متن کاملAutomatic Generation of Web-Based GIS/Database Applications
We have been developing web-based GIS/database (WebGD) applications that allow users to insert, query, update, and delete geographical features and the data associated with them from standard Web browsers. The code shared by these applications is organized as the WebGD framework. The behavior of the map interface of a WebGD application is defined by configuration files. We have built also the W...
متن کاملEvaluation of Updating Methods in Building Blocks Dataset
With the increasing use of spatial data in daily life, the production of this data from diverse information sources with different precision and scales has grown widely. Generating new data requires a great deal of time and money. Therefore, one solution is to reduce costs is to update the old data at different scales using new data (produced on a similar scale). One approach to updating data i...
