Fingerprint location algorithm based on K‐means for spatial farthest access point in Wi‐Fi environment

Algorithm Based on Point Feature for Fingerprint Image Segmentation

The segmentation of fingerprint images is very important to automatic fingerprint recognition system. To decide which part of the image belongs to the foreground and which part to the background, different methods have been proposed. Some of the traditional methods are introduced and implemented in this paper and a novel pixel based fingerprint segmentation algorithm is proposed. Two kinds pixe...

The New Algorithm of Fingerprint Reference Point Location Based on Identification Masks

Improvements of Indoor Fingerprint Location Algorithm based on RSS

With the development of the Internet, the technology of location fingerprint is widely used because of the advantage in indoor positioning performance of complex environment. K neighbor algorithm based on signal strength is a common position fingerprint matching algorithm. This paper firstly introduces the KNN fingerprint localization algorithm, and points out the deficiency of the algorithm. T...

Robust Point-Based Feature Fingerprint Segmentation Algorithm

A critical step in automatic fingerprint recognition is the accurate segmentation of fingerprint images. The objective of fingerprint segmentation is to decide which part of the images belongs to the foreground containing features for recognition and identification, and which part to the background with the noisy area around the boundary of the image. Unsupervised algorithms extract blockwise f...

fault location in power distribution networks using matching algorithm

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...
