The basic developing a digital image watermarking (DIW) objective approach is to satisfy both robustness and imperceptibility requirement. Digital watermarking (DW) appears as …

Steganography is a data hiding technique that is widely used in various information securing applications. Steganography transmits data by hiding the existence of …

A novel edge-preserving image decomposition based on saliency map is proposed to avoid halo phenomena in traditional image decompositions. Our method uses feature …

Image Enhancement is a process of improving the quality of an image by improving the contrast of the images. Images acquired underwater usually …

In this letter, we propose a new adaptive weighted mean filter (AWMF) for detecting and removing high level of salt-and-pepper noise. For each …

A novel content-based image retrieval (CBIR) schema with wavelet and color features followed by ant colony optimization (ACO) feature selection has been proposed …

The image descriptors based on multi-features fusion have better performance than that based on simple feature in content-based image retrieval (CBIR). However, these …

Content based image retrieval technique is done by three primitive methods namely through color, shape and texture. This paper provides specified path to …
