Irregular Workpiece Template-Matching Algorithm Using Contour Phase
نویسندگان
چکیده
The current template-matching algorithm can match the target workpiece but cannot give position and orientation of irregular workpiece. Aiming at this problem, paper proposes a for workpieces based on contour phase difference. By this, one firstly gain profile curve by measuring its radius in orderly fashion then, calculate similarity template phase-shifting finally, compute rotation measure between two according to number movements. experimental results showed that way could not only shaped base accurately, also accurately angle relative with maximum error controlled within 1%.

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
An Eye-Contour Extraction Algorithm from Face Image using Deformable Template Matching
A variety of studies on face components such as eyes, lips, noses, and teeth have been proceeding in medicine, psychology, biometrics authentication, and other areas. In this paper, we present an algorithm of extracting eye contours from a face image using the deformable template matching method. Our template for an eye contour is composed of three quadratic functions for the perimeter and one ...
متن کاملColor Image Registration and Template Matching Using Quaternion Phase Correlation
Due to mathematical limitations, conventional phase correlation technique can only be applied to grayscale images or at most complex images. A full colour image must be first converted to a grayscale image before performing the phase correlation, during which the luminance information has been wasted. In this paper, an extension of the phase correlation technique to the quaternion field , based...
متن کاملImage Tracking Algorithm using Template Matching and PSNF-m
The template matching method is used as a simple method to track objects or patterns that we want to search for in the input image data from image sensors. It recognizes a segment with the highest correlation as a target. The concept of this method is similar to that of SNF (Strongest Neighbor Filter) that regards the measurement with the highest signal intensity as target-originated among othe...
متن کاملContour Matching Using Epipolar Geometry
Generally contour matching is diicult, and the problem becomes more diicult when the motion between successive image frames is large. When the image frames are obtained while the camera is in motion, we can use constraints about the scene and the camera. In this paper we propose a contour matching algorithm which guarantees an accurate matching result, even for large motion contours. The key id...
