Research of Image Matching Based on Improved SURF Algorithm
In the study, it presents an efficient algorithm based on SURF (Speeded Up Robust Features). The method applies the SURF algorithm in the detection and description for image features, first it applies the SURF feature detector in extracting reference images and matching feature points in the image, respectively, then it uses DAISY algorithm instead of the SURF algorithm to calculate the charact...
متن کاملVisual indexing and retrieval
The second chapter provides a deep overview of the basic visual feature extraction and description methods and approaches in the literature for images as well as for spatio-temporal data analysis. The chapter aims to clarify the process of the main recognition steps of detection and description of image. Interest point detection approaches, point-based and region-based detectors, the spatiotemp...
متن کاملA Study on Moving Object Tracking Algorithm Using SURF Algorithm and Depth Information
This paper is a study on real-time object tracking algorithm using depth information of the Kinect and fast speeded up robust feature(SURF) algorithm. Depth information of the Kinect is used to overcome the disadvantage which continuously adaptive meanshift(Camshift) and Meanshift have of illumination and noise. Because processing time of SURF algorithm is faster than that of scale invariant fe...
متن کاملVideo Stabilization using Hybrid of SIFT and SURF Algorithm
Video stabilization is an important enhancement techniques used to remove undesired motion in a video. The sphere of photo forensics is expanding hastily. Many passive photograph tamper detection techniques were presented techniques have been presented. Some of those techniques use characteristic extraction methods for tamper detection and localization. This work is based totally on extracting ...
متن کاملNanjing University in TRECVID 2009_final
This report describes the details of our system for copy detection task in TRECVID 2009. We submitted 4 runs, 2 for video-only queries and 2 for video + audio queries. Details are listed below. Each group is with same technique but different parameters. NJU.v.balanced.1, NJU.v.nofa.1: SURF feature is used. Videos are indexed with feature points. We adopt LSH as indexing technique. NJU.m.balance...
