An improved SIFT method for pitch estimation of speech
The 2010 International Conference on Apperceiving Computing and Intelligence Analysis Proceeding, 2010This paper presents an improved SIFT (Simplified Inverse Filtering Technique) method for accurate pith estimation. In order to save computing time as well as ensuring the precision of autocorrelation, different re-sampling ratios are utilized during the process of LPC (Linear Predictive Coding) coefficients analysis and inverse filtering respectively ...

An Improved Image Registration Method Based on SIFT
2009 International Asia Symposium on Intelligent Interaction and Affective Computing, 2009The 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 ...

A copy-move forgery detection method based on CMFD-SIFT
Multimedia Tools and Applications, 2017A very common way of image tampering is the copy-move attack. When creating a copy-move forgery, it is often necessary to add or remove important objects from an image. To carry out forensic analysis of such images, various copy-move forgery detection (CMFD) methods have been developed in the literatures.

A SIFT-point distribution-based method for head pose estimation
2012 IEEE International Workshop on Machine Learning for Signal Processing, 2012Estimating the head pose of a person in a video or image sequence is a challenging problem in computer vision. In this paper, we present a new technique on how to estimate the human face pose from a video sequence, by creating a probabilistic model based on the scale invariant features of the face. This method consists of four major steps: (1) the face

Image Matching for Geomorphic Measurement Based on SIFT and RANSAC Methods
2008 International Conference on Computer Science and Software Engineering, 2008To effectively realize the image feature matching for geomorphic reverse measurement and rebuilding, a new matching scheme is presented, where the SIFT method are adopted to implement initial geomorphic image matching by going through five stages: scale-space construction, scale-space extrema detection, orientation assignment, keypoint descriptor and ...

A novel image registration method based on SIFT and verification mechanism
2017 2nd International Conference on Advanced Robotics and Mechatronics (ICARM), 2017Image registration has been widely used in image mosaic, medical image processing, robot vision, pattern recognition and other fields. Normally, the similarity measure that measures the similarity between feature point structures is employed to determine whether feature points in the image are matched to those in the reference image.
