If we use the image haze removal of dark channel prior, we're prone to color distortion phenomenon for some large white bright area in the image. Aimed at these problems, this paper presents an image haze removal of wiener filtering based on dark channel prior. The algorithm is mainly to estimate the median function in the use of the media filtering method based on the dark channel, to make the media...
This paper presents the results of applying Haralik's textures in the upland landform classification process. In environmental and landuse projects is important to know what kind of landforms are present in a geographic area. The objective of this work is to improve the performance of such classifications, adding information to the commonly used data features in such problems. The texture information...
This document presents the results of the implementation of three classical path planning algorithms for mobile robots in structured environments (Voronoi diagrams, visibility graphs and cell decomposition), using mobile robot platform Pioneer 3DX and a global vision system. Also this document shows a comparision of generated paths by each implemented algorithm, based on different criteria, (Path...
Different techniques for tracking objects in controlled environments using video cameras have been proposed. These state of the art algorithms are focused especially on how to find a better segmentation of the tracking object and also on how to make this segmentation stable through time, regardless of temporal changes on the morphology of the object. Unlike any of that, this article reviews the state...
Visible watermarking mechanism often used to claim the copyright of the protected media from the human visual perception. As a result of the visible logo superposes the media content, the visible logo inevitable distorts the content and degrades the readability of digital media. To diminish the visual distortion but preserve the advantages of visible watermarking technique, in this paper, we proposed...
Development of a multimedia website for direct multimedia data distribution between the creators (photographers or music bands or movie producers) and the end users (images for websites or companies or magazines or music for daily web-surfers or any company or advertisement). The multimedia data gets stamped with some recognizable feature using steganography and thus offers great potential for securing...
Content printed on the paper media is not rewritable, but its appearances can be controlled by illumination. In this paper, we propose a new method to represent three-dimensional (3-D) shape on the print media by the shading animation using projector-camera feedback. The proposed method consists of a hue, saturation, and value (HSV) map and an appearance control technique, and these are key technologies...
Reference feedback contains the positive and negative feedback ranks. User¡¦s relevance feedback rank can derivate as the User¡¦s preference. In this paper, we addressed the user¡¦s relevance feedback technology to reflect the degree of user¡¦s preferences of what he liked. The personal preference and general preference could be considered in this paper. The dynamic re-ranking result will refer to...
Steganalysis is the science of detecting the presence of hidden information in media files. In this paper, we propose a simple scheme based on close colours that detects not only the presence of hidden information but also the size of the hidden information. The scheme applies to synthetic digital images with a small number of distinct colours (such as logos and flags). We compare our scheme to another...
This paper proposes an approach whereby the regional contrasts in snap-shot style portrait photographs are enhanced using pre-modern portrait paintings as aesthetic exemplars. The reference portrait painting is selected based on a comparison of the existing contrast properties of the painting and the photograph. The contrast style in the selected reference painting is transferred to the photograph...
Digital watermarks provide the capability to insert additional information onto various media, such as still images, movies, and audio, by utilizing features of the content. Several methods that use features of the content, such as text or images, have already been proposed for printed documents. To overcome the disadvantages of the existing methods, we have proposed a new information hiding scheme...
Recent development of information technology enables us to use fragrance as media content. The additional use of fragrance to information of sight will achieve higher effects in Web browsing than ever. Referring to the previous studies, this study fundamentally investigated the relationship between color and fragrance. Ten subjects participated in two experiments. In the experiment 1, impressions...
The goal of this work is to automatically detect frequently occurring groups of media in a user's collection that have a unifying theme. These groups provide a narrative structure that ties in images that are temporally far apart and cannot be browsed easily. The media in the collection is analyzed by a variety of algorithms to generate metadata of different types. The media and associated metadata...
In this paper, we propose a lossless data hiding algorithm for grayscale images. Specifically, our technique is based on the cluster-based difference expansion transform. The main scenario behind our technique is that we use a recursive cluster construction technique to divide the input image into several clusters. In the data embedding process, a modified difference expansion transform is used to...
Generic Steganalysis aims to detect the presence of covert communication by identifying the given test data as stego / cover media. Thresholded adjacent pixel differences using different scan paths have been used to highlight feeble embedding artifacts created out of a low rate embedding process. The scan paths normally made use of in the embedding process have been utilized for a steganalytic scheme...
The use of Information and Communication Technologies (ICT) in primary schools allowed to exploit the potential of these technologies as a means of assisting students in their learning process. Nowadays, with the use of ICT, the student is becoming aware of the processes and strategies that use. The present work has the main purpose to improve the teaching/learning process. Thus, the student with...
Human-computers interaction is a field of study that has been discussed from the beginning of computers technology. The main purpose of it is to make a more comfortable ways to interact with the computers that consist of accuracy, mobility, and speed. A new intuitive and revolutionary way to interact with computer is the use of webcam as a keyboard as keyboard is the most fast and accurate input device...
Interaction design plays a very important part in the digital media industry. This paper will take the interaction design of virtual home furnishing display as an example and analyze the multiple approaches and relevant design principles applied to this particular field, so that we can give some guide instructions to the interaction design of the home furnishing display platform.
Fast media search and browsing is today a growing need to face the challenge of managing large collections of personal media. Traditional databases, (e.g. MySQL), or text databases (e.g. Lucene), do not address an important aspect of multimedia data: the high-dimensionality of data. In this paper, we describe the implementation and evaluation of high-dimensional data indexing structures for fast search...
In order to solve emotional absence of visceral layer, behavioral layer and reflective layer of web-based curriculum, emotionalized design theory is applied to build the frame of it. By designing from three aspects, which are inner feeling of the interface design, behavioral experience of the interactive design and reflective record of thoughtful reaction, emotionalized frame embedded into network...
