Feature Extraction Techniques Based on Color Images
-------------------------------------------------------------------ABSTRACT----------------------------------------------------------------Nowadays various applications are available that claim to extract the correct information from such colored image databases which have different kinds of images and their own semantics. During information extraction based on the content of images various kin...
متن کاملOverlap-based feature weighting: The feature extraction of Hyperspectral remote sensing imagery
Hyperspectral sensors provide a large number of spectral bands. This massive and complex data structure of hyperspectral images presents a challenge to traditional data processing techniques. Therefore, reducing the dimensionality of hyperspectral images without losing important information is a very important issue for the remote sensing community. We propose to use overlap-based feature weigh...
متن کاملReview and Comparison of Various Feature Extraction Techniques in CBIR
In fields such as medical, art galleries, museums, archaeology, medical imaging, trademark databases, criminal investigations, images especially the digital images grow in quantities of thousands and sometimes even lakhs every year. Content based image retrieval is required from such large databases. This paper compares various CBIR techniques based on difference in generating feature vectors i...
متن کاملRoad Extraction from Color Imagery
The detection of boundaries in the field of digital photogrammetry and image analysis is still a challenging area of research. Contour models recently gained a lot of attention for recovering and localizing edge structures and thus are useful for facilitating the image segmentation problem. Their use has been extended for describing man-made structures such as roads and buildings from gray-leve...
متن کاملPolygon Feature Extraction from Satellite Imagery Based on Colour Image Segmentation and Medial Axis
Areal features are of great importance in applications like shore line mapping, boundary delineation and change detection. This research work is an attempt to automate the process of extracting feature boundaries from satellite imagery. This process is intended to eventually replace manual digitization by computer assisted boundary detection and conversion to a vector layer in a Geographic Info...
