Duplicate Video Detection - Comparison of Proposed Distance Function with Dynamic Time Warping and Dependence of Detection Accuracy on Keyframe Selection

چکیده
The problem we are considering here is duplicate video detection. We have a database of N videos and we store compact signatures, called fingerprints, for each of them. When a query video is presented, the system first returns the top-K most closely matched videos. Then, a more detailed search is performed among the top-K retrieved model videos to obtain the best match. Finally, a separate module is used to confirm whether the best matched video is indeed a duplicate. A complete overview of our duplicate detection framework is shown in Fig. 1. In this write-up, we focus on two aspects:

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard
Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملA New Method for Duplicate Detection Using Hierarchical Clustering of Records
Accuracy and validity of data are prerequisites of appropriate operations of any software system. Always there is possibility of occurring errors in data due to human and system faults. One of these errors is existence of duplicate records in data sources. Duplicate records refer to the same real world entity. There must be one of them in a data source, but for some reasons like aggregation of ...

This paper aims to develop a writing robot by recognizing the speech signal from the user. The robot arm constructed mainly for the disabled people who can’t perform writing on their own. Here, dynamic time warping (DTW) algorithm is used to recognize the speech signal from the user. The action performed by the robot arm in the environment is done by reducing the redundancy which frequently fac...
