In this paper, issues and challenges on digital media, with a focus on video, content management and protection for sharing on the Internet are discussed. High speed wired and wireless networks have helped to facilitate and speedup video transmission and streaming. Hence, the amount of video sharing on the Internet has dramatically increased. This paper will discuss current and future trends of digital...
In this paper, we propose an algorithm for video signature using music videos and news video for our study. The algorithm was developed based on our earlier work with an improvement (reducing the steps) on the process of generating video signature. Thus, revised process reduces the amount of processing time needed tremendously. In addition, besides color as a feature, we introduce the addition of...
This paper discusses the history and current trends of video retrieval, focusing mainly on video segmentation, indexing and search. The objective is to share with the readers how much we have done so far as well as the current trends in the field. Unlike text documents, video contains dynamic information such as audio, motion (object and/or camera motions), etc. Thus, indexing videos for future search...
In this paper, we present a framework called ldquoWhat-you-seeis- what-I-see (WYSIWIS)rdquo. The framework describes a new trend for multimedia information (such as images and videos) sharing using an Eyetap device and a method to retrieve similar multimedia content. This Eyetap device is equipped with a video camera and networking capability. It can be used to capture an image or recording a video...
One of the long-term goals in human-computer interaction is to utilize more intuitive and natural methods such as speech and hand gestures that a user would employ for communication. In this paper, we present a robust method of hand tracking using a probability map computed from a joint probability function derived from both depth information and skin-tone information. The depth information is provided...
There is a wide range of work detailing the effect of colorspace on the detection of skin tone pixels. However, one important consideration which has been overlooked is the effect of dynamic range compression. Specifically, many very commonly used file formats (JPEG, PNG, GIF, etc.) use dynamic range compression to compensate for the range expansion implicit in many display systems. When building...
One of the goals of human-computer interaction is to utilize more intuitive and natural methods for communication. This goal has become of particular importance in augmented reality (AR) applications. Developing such interaction techniques is critical since traditional interfaces (keyboard, mouse) are cumbersome and awkward in AR environments. This paper provides a description of a real-time interactive...
We propose a single figure-of-merit measure of resolution of a digital imaging system based on the work of Gabor in communication theory. Gabor's work was largely inspired by Heisenberg's developments in quantum theory, most notably his uncertainty theorem of quantum mechanics. Gabor's results look simultaneously at the frequency and spatial domain of a signal, making it ideal for the measure of the...
A noise model that is generated from pictures taken by differently illuminating the same subject matter is presented. The superposigram, a three dimensional structure based on three different illuminations of the subject matter is used to directly calculate the noise present in the images which is attributable to the noise originating in the sensor array. Though a similar method has been used to determine...
The placement of a tracheostomy tube in the neonatal patient poses special technical challenges to the surgeon. A direct laryngoscopy and bronchoscopy are often part of the airway evaluation and frequently precede a tracheostomy. Leaving a rigid bronchoscope in place in the tracheal lumen for the tracheostomy is a variation on the standard technique in which reintubating the patient generally follows...
