SIFT method for paper detection system

2011 International Conference on Multimedia Technology, 2011
Traditional detect method could not deal well with the problem of paper zooming. This paper introduces scale invariant feature transform to the paper detection system. The hardware of paper detection system consists of digital signal processor and complex programmable logic device. The hardware can accomplish image acquisition and processing.

SiFT: An efficient method for Trajectory Based Forwarding

2005 2nd International Symposium on Wireless Communication Systems, 2005
Trajectory based forwarding (TBF) is a new approach for routing in ad hoc wireless networks. It assumes that nodes know their position and, similarly to source routing, requires the source node to encode a trajectory into the packet header. However, trajectories are just geometrical lines and the routing process does not require specifying forwarding ...

Coin Recognition Method Based on SIFT Algorithm

2017 4th International Conference on Information Science and Control Engineering (ICISCE), 2017
Coin recognition is one of the prime important activities for modern banking and currency processing systems in which machine vision is widely used. The technique at the heart of such systems is object recognition in a digital image. Although it has high recognition speed, the traditional method of coin recognition can not recognize the coins with ...

PLANER OBJECT DETECTION USING SURF AND SIFT METHOD

International Journal of Engineering Applied Sciences and Technology, 2022
Object Detection refers to the capability of computer and software to locate objects in an image/scene and identify each object. Object detection is a computer vision technique works to identify and locate objects within an image or video. In this study, we compare and analyze Scale-invariant feature transform (SIFT) and speeded up robust features ...

A sift-based method for image mosaic

2010 3rd International Conference on Advanced Computer Theory and Engineering(ICACTE), 2010
This paper proposes a mosaic algorithm based on SIFT(Scale Invariant Feature Trasform). Keypoints and their descriptors are exacted by SIFT, which ensures the algorithm robust to translation, rotation, noise and scalling. Then proposed matching algorithm is used to match the keypoints. First, rough match pairs are obtained by Nearest Neighbor algorithm.

A Method of Acceleration Applied in Symmetric-SIFT and SIFT

2013
Symmetric-SIFT is an effective technique used for registering multimodal images. It is based on a well-known image registration technique named Scale Invariant Feature Transform (SIFT). Similar to SIFT, Symmetric-SIFT detects many stable keypoints even though not all of which are useful.

Recognition of Expression-Variant Faces Using SIFT Method

2012 Fourth International Conference on Computational Intelligence and Communication Networks, 2012
Prior research has shown that the performance of face recognition systems in variant expression condition degrade seriously compared with invariant expression condition. Face recognition with variant expression is a challenging problem. In this paper, SIFT method is proposed to research on face recognition with variant expression. Two experiments using

A Description Method for MSER with SIFT Descriptor

Applied Mechanics and Materials, 2011
Maximally Stable Extremal Regions are robust to complex affine distortion and illumination changes between reference image and real-time image. On the basis of deeply research on the SIFT descriptor, this paper propose a description algorithm for MSER using SIFT descriptor.

An Improved Image Registration Method Based on SIFT

2009 International Asia Symposium on Intelligent Interaction and Affective Computing, 2009
The features of SIFT are widely used in image matching because of it’s invariantion to images scale and rotation, but 128-dimensional description of the feature point reduce the efficiency of the algorithm. This paper presents an improved algorithm of SIFT, using ring and sequence of each feature vector to ensure rotation invariance while reducing the ...

Normalization Methods of SIFT Vector for Object Recognition

2011 10th International Symposium on Distributed Computing and Applications to Business, Engineering and Science, 2011
In the clustering of key points, the ratio of inter-class distance and intra-class distance is enlarged using Normalized SIFT vectors. In order to significantly make the ratio larger, a new normalization method is proposed, which is termed the i®normalization method based on seedpoints'. In image preprocessing, for the removal of the object background,
