Object Selection by Grouping of Straight Edge Segments in Digital Images
نویسندگان
چکیده
A new method for finding geometric structures in digital images is proposed. An adaptive algorithm of straight line segments extraction is developed for manmade objects description in digital images. It uses an adjustment of oriented filter angle for precise extraction of line corresponding to real edge. Perceptual grouping approach is applied to these segments to obtain simple and complex structures of lines on the base of their crossings. Initial image is presented as a collection of closed structures with their locations and orientations. Applications to real aerial, satellite and radar images show a good ability to separate and select specific objects like buildings and other line-segment-rich structures.

Objects Description and Extraction by the Use of Straight Line Segments in Digital Images
An advanced edge-based method of feature detection and extraction is developed for object description in digital images. It is useful for the comparison of different images of the same scene in aerial imagery, for describing and recognizing categories, for automatic building extraction and for finding the mutual regions in image matching. The method includes directional filtering and searching ...
متن کاملFinding Poly-Curves of Straight Line and Ellipse Segments in Images
Simplification of given polygons has attracted many researchers. Especially, finding circular and elliptical structures in images is relevant in many applications. Given pixel chains from edge detection, this paper proposes a method to segment them into straight line and ellipse segments. We propose an adaption of Douglas-Peucker’s polygon simplification algorithm using circle segments instead ...
متن کاملContour Segment Matching by Integrating Intra and Inter Shape Cues of Objects
In this paper we propose an algorithm for contour-based object detection in cluttered images. Contour of an object shape is approximated as a set of line segments and object detection is framed as matching contour segments of an image (i.e.,an edge image) to a boundary model of an object (i.e., a line drawing). Local shape is abstracted as a group of k-adjacent segments. We use a multi-level sh...
متن کاملTracking of Convex Objects
In this paper, we present a technique for grouping line segments sinto convex sets, where the line segments are obtained by linking edges obtained from the Canny edge detector. The novelty of the approach is twofold: rst we de ne an e cient approach for testing the global convexity criterion, and second, we develop an optimal search based on dynamic programming or grouping the line segments int...
متن کاملDetection and recognition of contour parts based on shape similarity
Due to distortion, noise, segmentation errors, overlap, and occlusion of objects in digital images, it is usually impossible to extract complete object contours or to segment the whole objects. However, in many cases parts of contours can be correctly reconstructed either by performing edge grouping or as parts of boundaries of segmented regions. Therefore, recognition of objects based on their...
