Toward Image-Based Localization for AIBO Using Wavelet Transform
This paper describes a similarity measure for images to be used in image-based localization for autonomous robots with low computational resources. We propose a novel signature to be extracted from the image and to be stored in memory. The proposed signature allows, at the same time, memory saving and fast similarity calculation. The signature is based on the calculation of the 2D Haar Wavelet ...
متن کاملEnhanced Image Fusion Technique Based on Wavelet Transform
Image fusion practices permit the integration of different information bases. The merged image can have complementary, spatial and spectral resolution characteristics[1]. However, the typical image fusion methods can falsify the spectral information of the multispectral data, though merging. The hypothetical image fusion is done on the images which is taken, either by different sensors at the s...
متن کاملWavelet Transform Based Image Compression
Image require substantial storage and transmission resources, thus image compression is advantages to reduce these requirements. A good strategy of image compression should assure a good compromise between a high compression rate and a low distortion of the picture. In this paper a lossless digital image compression technique based on Integer Wavelet Transform is proposed. The small deviations ...
متن کاملWavelet Based Contourlet Transform for Image Compression
Wavelet transforms are not capable of reconstructing curved images perfectly, hence we go for this new concept, called Contourlet Transform. It is a multiresolution and directional decomposition of a signal using a combination of Laplacian Pyramid (LP) and a Directional Filter Bank (DFB). The Contourlet transform has good approximation properties for smooth 2D functions and finds a direct discr...
متن کاملImproved Image Steganography Technique for Colored Images using Wavelet Transform
Steganography is the most used technique for data hiding. We can implement it using any cover media like text, images, and videos. In this paper we devised a new algorithm to hide our text in any colored image of any size using wavelet transform. It improves the image quality and imperceptibility. Our method sustains the security attacks. Extensive testing is performed using different sizes of ...
