The usage of smartphone nowadays has been increasingly and most of people in the world use it. Following this development a wide variety of applications for mobile phones have been created. After all, most people use the smartphone to browse social networks, listen to music, play games, make memos upload photos to Instagram, accessing banking services, as well as data sharing through cloud system...
This paper presents SpaceViz, an information visualization tool designed for depicting hierarchies, such as directory structures. SpaceViz has scanned, map and manage PC, network and cloud storage of multimedia data. Classical, space-filling squarified techniques are used as methodology, but differ from Tree-map single view in that it employs multiple views in two-dimensional space, which is used...
In this paper, we propose a color image processing method based on a finite field cosine transform (FFCT). Basically, the approach consists in applying a 32-point FFCT over GF(224) to blocks of a color image. Since RGB images are considered, each pixel of the corresponding image blocks can be represented as a binary 24-tuple and then treated as an element of GF(224). By means of computer experiments,...
Gloves and sensor based trackers are unwieldy, constraining and uncomfortable to use. Since there are limitations of these devices the useable command set based diligences is also limited. This research project deals with using appropriate image processing algorithms to recognize hand gestures and then performs actions depending on the gesture made. The gesture does not require any skills or prior...
Multiple-query image retrieval is usually utilized in order to enhance performance of the image retrieval system with considering single semantic for a query set. So far, multiple-query image retrieval based on different queries has rarely studied. In this work, we intend to address this problem using a binary component vector. This vector indicates distinct components which exist in an image. The...
Elephant intrusion in areas with high human movement can prove lethal for both human beings and elephants. The proposed system seeks to identify elephants with the aid of a Video Camera. The suggested methodology was applied to zones having high intervention of human beings and elephants. Regions with higher human movements like roads were extracted from the initial video frames. This process is followed...
Text Steganography is a field of hiding text messages into multimedia (e.g. image) documents. In this method we apply DWT on input image to divide it into four sub-band. We will work on low frequency band. After hiding the text information the picture has been compressed for reducing the memory. The method which is used for the compression is Discrete Wavelet Transform (DWT), for recovery of the original...
Developers' daily work produces, transforms, and communicates cross-cutting information across applications, including IDEs, emails, Q&A sites, Twitter, and many others. However, these applications function independently of one another. Even though each application has their own effective information management mechanisms, cross-cutting information across separate applications creates a problem...
This conceptual paper examines the computer identification of signs called day markers that commonly appear for navigation purposes in a marine channel waterway. Most people are familiar with these signs when navigating in a boat as they appear either as red triangles, green rectangles or diamonds since they aid navigation through the channel. The paper focuses on a proposed classifier using Procrustes...
In order to solve existent questions of CAI (Computer Aided Instruction) in university teaching, the course of Elements of Information Theory was taken as an example to describe how to use the CAI. According to characteristic of this course and teaching law, CAI could be used correctly and reasonably by some methods which could wake up the interest of students, such as the combination between writing...
Pan-Tilt-Zoom (PTZ) cameras play an important role in surveillance systems. In this paper, we propose an active tracker using color silhouettes with a single camera. We firstly apply dilation and erosion operators of morphology to binary difference image to get color silhouettes. We also record the color silhouette of the target which we are interested in. Secondly, we measure the similarity of color...
Scribble-based colorization algorithms have become greatly popular due to the ease of user interaction. The key of propagating the user scribbles to the entire image is to define a similarity measure between pixels. We propose here a new affinity function with several computation times of similarity weights for each pair of adjacent pixels, while the traditional methods only with one such computation...
This paper presents an educational software which is applied for cognitive improvement of color aptitude in teaching engineers in Hungary. Our interactive software called VIOLA can support the learning of basics on color theory, putting them into practice, and also provides interactive test questions that can be used to measure the students' skills on color determining and distinguishing. The efficiency...
Image colorization is the technology used to add colors to a grayscale image by computers. A novel image colorization method based on local and global consistency is proposed, which uses an oversegmentation-based graph model and a modified energy function to take advantage of the local and global information of each pixel. An oversegmentation-based graph model is used to approximate each pixel by...
Human computer interaction (HCI) is a classic topic, and hand gesture is one of the most natural languages, so the key point in human computer interaction is hand gesture recognition. A skin color model based on Hue is utilized to detect skin color regions like hands. To distinguish the face and hand, a simple and fast hand segmentation algorithm is developed. Moreover, we use the least square method...
Most image cluster algorithms group images based on the content, that can be described with some low-level image features or geometry features. In this paper, we proposed novel grouping criteria for image cluster from a aesthetic perspective. By studying the skills and techniques of professional photographers, we introduce several image features that can describe the styles of photographs. And we...
Analyzing how software engineers use the Integrated Development Environment (IDE) is essential to better understanding how engineers carry out their daily tasks. SPOTTER is a code search engine for the Pharo programming language. Since its inception, SPOTTER has been rapidly and broadly adopted within the Pharo community. However, little is known about how practitioners employ SPOTTER to search and...
This work deals with web technologies in industrial HMI systems. We created, designed and developed a HMI framework, which is based on web and cloud technologies. We also compared our system with available commercial solutions and described their advantages and disadvantages. The outcome of this work is not only a comparison of available solutions, but also the created framework and demo application...
The motivation behind this work is to explore and pursue benefits of Cognitive Informative and Artificial Intelligence. Computer based Image Analysis and Machine Vision are based on Image Processing Algorithms. Choosing the best concept to comprehend a meaning in natural language generation is one of the tough tasks. A vision system while navigating in an environment should be able to recognize what...
Glaucoma is the major reason that causes blindness today. It results in total loss of vision which is irreparable which makes it mandatory to detect it at early stages. This paper proposes a simple method to evaluate the Cup-to-Disc Ratio (CDR) of a retinal fundus image to screen it for Glaucoma. It is a contrasting feature taken up to check whether the subject is at risk for Glaucoma or not. The...
