Digital Correlation based on Wavelet Transform for Image Detection
In this work is presented a method for the optimization of digital correlators to improve the characteristic detection on images using wavelet transform as well as subband filtering. It is proposed an approach of wavelet-based image contrast enhancement in order to increase the performance of digital correlators. The multiresolution representation is employed to improve the high frequency conte...
متن کاملEdge Detection with Hessian Matrix Property Based on Wavelet Transform
In this paper, we present an edge detection method based on wavelet transform and Hessian matrix of image at each pixel. Many methods which based on wavelet transform, use wavelet transform to approximate the gradient of image and detect edges by searching the modulus maximum of gradient vectors. In our scheme, we use wavelet transform to approximate Hessian matrix of image at each pixel, too. ...
متن کاملA Hybrid Method for Mammography Mass Detection Based on Wavelet Transform
Introduction: Breast cancer is a leading cause of death among females throughout the world. Currently, radiologists are able to detect only 75% of breast cancer cases. Making use of computer-aided design (CAD) can play an important role in helping radiologists perform more accurate diagnoses. Material and Methods: Using our hybrid method, the background and the pectoral muscle...
متن کاملBiorthogonal Wavelet Transform Digital Image Watermarking
With the growing popularity of Digital Medias through the World Wide Web, intellectual property needs copyright protection, prevention of illegal copying and verification of content integrity. The new data hiding techniques need to be developed that satisfy the requirements of Imperceptibility, Robustness, Capacity, or data hiding rate and Security of the hidden data etc. Watermarking has been ...
متن کاملImage Dithering Based on the Wavelet Transform
In this paper, a method for compensating the softening effect of the error diffusion algorithms, and a new dithering technique that emphasizes the details of images and is based entirely on the wavelet transform, are presented.
