In many computer vision tasks
in order to improve the accuracy and robustness to the noise
wavelet analysis is preferred for the natural multi-resolution property. However
the wavelet representation suffers from the dependency of the starting point of the sampled contour. For overcoming the problem that the wavelet representation depends on the starting point of the sampled contour
the Zernike moments are introduced
and a novel Starting-Point-lndependent wavelet coefficient shape matching algorithm is presented. The proposed matching algorithm firstly gains the object contours
and give the translation and scale invariant object shape representation. The object shape representation is converted to the dyadic wavelet representation by the wavelet transform. And then calculate the Zernike moments of wavelet representation in different scales. With respect to property of rotation invariant of Zernike moments
consider the Zernike moments as the feature vector to calculate the dissimilarity between the object and template image
which overcoming the problem of dependency of starting point. The experimental results have proved the proposed algorithm to be efficient
precise
and robust.

This paper proposed a new approach for the removal of mixed noise. There are many different ways in image denoising. Donoho et al have proposed a method for image de-noising by thresholding
ambiguity is often resulted in determining the correspondence of a modulus maximum to a singularity. In the light
and indeed
we combine the merits of the two techniques to form a new approach for the removal of mixed noise. At first
the application of their method to image denoising has been extremely successful. But the method of Donoho is based on the assumption that the type of noise is only additive Gaussian noise
we used wavelet singularity detection (WSD) technique to analyze singularities of signal and noise. According to the characteristic that wavelet transform modulus maxima of impulse noise rapidly decreases as the scale increases in wavelet domain
which is not successful for impulse noise. Mallat has also presented a method for signal denoising by discriminating the noise and the signal singularities through an analysis of their wavelet transform modulus maxima (WTMM). Nevertheless
it can be accurately located with multiscale space by going through dyadic orthogonal wavelet transform and removed. Furthermore the Gaussian noise is also removed through a level-dependent thresholding algorithm
the tracing of WTMM is not just tedious procedure computationally
algorithm. The experimental results demonstrate that the proposed method can effectively detect impulse noise and remove almost all of the noise while preserve image details very well.
