Characterization of Dirac Edge with New Wavelet Transformre edge forms two new curves which are located symmetrically at the two sides of the original one and have the same direction with it and the distance between the two curves is estimated. An algorithm to detect curves in an image by utilizing the above invariants is developed. Several experiments are conducted, and positive results are obtained.

Three Novel Models of Threshold Estimator for Wavelet Coefficientsctively. They all overcome the disadvantages of the hard- and soft-thresholding method. Finally, an example is given and the experimental results showt hat the improved techniques presented in this paper are efficient.

Image-Feature Based Second Generation Watermarking in Wavelet Domainpted watermarked image corresponding to the approximate coefficients at the same position as the original featured approximation coefficients is calculated and compared to a predefined threshold to see if the watermark is present. Experimental results show the watermark is very robust to common image processing, lossy compression in particular.
