Content-based multimedia information retrieval is an interesting but difficult research. Current approaches include the use of color, texture, and shape information. In this paper, we present a hybrid approach, which incorporates color, shape and spatial relations among objects in a picture, to retrieve images from nearly 5000 pictures. A revised color(More)
We propose a new approach to retrieve images from an image MTM (Mathematical Transform to Munsell) for filtering out the non-similar images effectively. Then, we combine the color and spatial relationship of objects to measure the similarity of images. . . database. We combine both color and spatial features of a picture to index and measure the similarity(More)
A lossy compression tolerant data hiding method is proposed in this paper. The image which hides data is named a stego-image. Most of data hiding methods will lose some hidden data when the stego-image is compressed by lossy compression process. However, there are few people will transmit image without lossy compression in the public internet. By the(More)
In this paper, we provide color, shape and spatial relations approach to retrieve images. User can flexible use this three methods by select their weight to retrieve images from nearly 5000 pictures. We propose a revised automatic indexing scheme of image database according to our color clustering method, which could filter the image efficiently. As a(More)
This paper presents a review of the literature on the use of artificial neutral networks in digital watermarking. Digital watermarking is a recent technology evolved to prevent illegal copy or reproduction of digital content. Different neural network based approaches have been categorized based on their applications for embedding and extracting components(More)
