چکیده

Pixel-by-pixel template matching is very time-consuming. For an input image of size N N × , and the template of size W W × , the computational complexity is O( 2 2 N W‧ ), given that the object orientations in both images are coincident. When we search an object with unknown orientation, the straightforward way to do template matching is to rotate the reference template in every possible orientation. It makes the matching scheme become impractical when arbitrary rotation of a search object is present.

General Stereo Image Matching Using Symmetric Complex Wavelets

General stereo image matching provides an adequate but hard problem with suucient complexity, with which the potential of wavelets may be exploited to a full extent. An ideal stereo image matching algorithm is supposed to be invariant to the scale, translation, rotation, and partial correspondence between two given stereo images. While the multiresolution of wavelets is good at scale adaptivity...

Efficient Algorithms for Invariant Discrete Wavelet Decomposition

Classical discrete wavelet packet transforms are sensitive to changes in image orientation and translation. Therefore, it is hardly possible to extract rotation invariant features from images in the transform domain. This paper proposes several algorithms for invariant discrete wavelet decomposition to produce an invariant representation for an image. The procedure can be divided into several s...

Shape Matching Using Wavelet Transform Modulus Maxima

Object contour matching has been prevalently used in pattern recognition and content-based indexing and retrieval of digital images. In this paper, the contour descriptors are extracted from a WTMM (Wavelet Transform Modulus Maxima) image, which is produced by a one level biorthogonal wavelet transform and contains curvature points of the contour. The most important WTMMs are further utilized t...
