Description: This project focuses on calculating the similarity between the images using genetic algorithm and haar-wavelet. Haar wavelet is being used in order to calculate the images with different features like various expressions or gloomy or other characteristics.
This system extracts the feature from images by wavelet transform, and provides a user-friendly means to retrieve an image from a large database when the user cannot clearly define what the image must be. Platform: |

Description: This paper proposes new watermarking technique
based on tetrolet domain. The tetrolet transform is a new
adaptive Haar-type wavelet transform based on tetrominoes. It
avoids Gibbs oscillation because it applies the Haar function at
the edge of the image. Our proposed watermarking algorithm
embeds the watermark into the tetrolet coefficients which are
selected by considering different of shapes tetrominoes. We
uated the effectiveness of the watermarking approach by
considering the quality metrics like RMSE, PSNR and
Robustness parameters. The experimental results reveal that the
proposed watermarking scheme is robust against common image
processing attacks. Platform: |
