The monogenic signal is the natural 2-D counterpart of the 1-D analytic signal. Shearlet transform combines the power of multiscale methods with a unique ability to capture the geometry of multidimensional data, which is optimally efficient in representing images containing edges. We construct a new shearlet monogenic analysis method using the monogenic and structure based method of the shearlet transform...
Time-frequency analysis method to locate the thin layer in GPR detection is proposed in this paper. It is used to improve the recognition ability of GPR. Several time-frequency analysis methods as Short Time Fourier Transform (STFT), Wavelet Transform (WT), S Transform, General S Transform and Wigner Transform are compared in this paper. Simulation and experiment results verify the effectiveness of...
Wavelet multiresolution analysis is widely used and achieves good results in image denoising fields. Wavelet transform has unique advantages in dealing with singular point, but has some disadvantages in dealing with the borders and the line features of the image. But curvelet transform has the finest approximation of the singular curve in the image. In this paper, we combine the wavelet transform...
Inpainting, the technique of modifying an image in an undetectable form, is as ancient as art itself. With the release of the new image compression standard JPEG2000, people pay more attention to the wavelet inpainting problems. We consider the problems of filling in missing or damaged coefficients in both spatial and wavelet domain. First, we propose an algorithm in order to restore long and narrow...
