In this proposed method, the Tamil language texts are analyzed through the Morris-Pratt Algorithm as input image that filtered with Gabor filter for edge analysis. Then, it converted into unique strings from the text blocks. The text strings consist of text stroke to analyze the pattern. By using wavelet transform, the features of pattern are extracted and it undergoes for mapping with the text...

One of the most remarkable properties of the continuous curvelet and shearlet transforms is their sensitivity to the directional regularity of functions and distributions. As a consequence of this property, these transforms can be used to characterize the geometry of edge singularities of functions and distributions by their asymptotic decay at fine scales. This ability is a major extension of ...

T2* and quantitative susceptibility mapping (QSM) of magnetic resonance imaging (MRI) images provide different type inner structure information of scanned organs. If they can be properly fused into one set, the details of the scaned organ can be revealed more clearly. In this paper, a 3D MRI image fusion method based on 3D compactly supported shearlet transform (3D-CSST) and 3D dual tree compac...

Ultrasound images suffer of multiplicative noise named speckle. Bayesian shrinkage in transform domain is a well-known method based on finding threshold value to suppress the speckle noise. The main problem of applying Bayesian shrinkage is finding the optimum threshold value in appropriate transform domain. In this paper, we compare the performance of adaptive Bayesian thresholding when nonsub...

It is now widely acknowledged that analyzing the intrinsic geometrical features of an underlying image is essentially needed in image processing. In order to achieve this, several directional image representation schemes have been proposed. In this report, we develop the discrete shearlet transform (DST) which provides efficient multiscale directional representation. We also show that the imple...

Digital images watermarking is a method for data hiding that ensures the security of multimedia data. In these ways, watermark can be digital image or stored within content. The Shearlet transform, multi-resolution and multi-directional conversion, used in images. Due to its superior features, this conversion increase efficiency applications such as paper, SVD transforms are with Whale optimiza...
