Video Analysis and Repackaging for Distance Education

Video Analysis and Repackaging for Distance Education PDF Author: A. Ranjith Ram
Publisher: Springer Science & Business Media
ISBN: 1461438373
Category : Computers
Languages : en
Pages : 178
Book Description
This book presents various video processing methodologies that are useful for distance education. The motivation is to devise new multimedia technologies that are suitable for better representation of instructional videos by exploiting the temporal redundancies present in the original video. This solves many of the issues related to the memory and bandwidth limitation of lecture videos. The various methods described in the book focus on a key-frame based approach which is used to time shrink, repackage and retarget instructional videos. All the methods need a preprocessing step of shot detection and recognition, which is separately given as a chapter. We find those frames which are well-written and distinct as key-frames. A super-resolution based image enhancement scheme is suggested for refining the key-frames for better legibility. These key-frames, along with the audio and a meta-data for the mutual linkage among various media components form a repackaged lecture video, which on a programmed playback, render an estimate of the original video but at a substantially compressed form. The book also presents a legibility retentive retargeting of this instructional media on mobile devices with limited display size. All these technologies contribute to the enhancement of the outreach of distance education programs. Distance education is now a big business with an annual turnover of over 10-12 billion dollars. We expect this to increase rapidly. Use of the proposed technology will help deliver educational videos to those who are less endowed in terms of network bandwidth availability and to those everywhere who are even on a move by delivering it effectively to mobile handsets (including PDAs). Thus, technology developers, practitioners, and content providers will find the material very useful.

Observing Teacher Identities through Video Analysis

Observing Teacher Identities through Video Analysis PDF Author: Amy Vetter
Publisher: Routledge
ISBN: 1317567013
Category : Education
Languages : en
Pages : 138
Book Description
Teaching is often seen as an identity process, with teachers constructing and enacting their identities through daily interactions with students, parents and colleagues. This volume explores how conducting video analysis helps teachers gain valuable perspectives on their own identities and improve classroom practice over time. This form of interactional awareness fosters reflection and action on creating classroom conditions that encourage equitable learning. The volume follows preservice English teachers as they examine video records of their practice during student teaching, and how the evidence impacts their development as literacy teachers of diverse adolescents. By applying an analytic framework to video analysis, the authors demonstrate how novice teachers use positioning theory to transform their own identity performance in the classroom. Education scholars, teachers and professional developers will greatly benefit from this unique perspective on teacher identity work.

Book Description
Music videos promote popular artists in cultural forms that circulate widely across social media networks. With the advent of YouTube in 2005 and the proliferation of handheld technologies and social networking sites, the music video has become available to millions worldwide, and continues to serve as a fertile platform for the debate of issues and themes in popular culture. This volume of essays serves as a foundational handbook for the study and interpretation of the popular music video, with the specific aim of examining the industry contexts, cultural concepts, and aesthetic materials that videos rely upon in order to be both intelligible and meaningful. Easily accessible to viewers in everyday life, music videos offer profound cultural interventions and negotiations while traversing a range of media forms. From a variety of unique perspectives, the contributors to this volume undertake discussions that open up new avenues for exploring the creative changes and developments in music video production. With chapters that address music video authorship, distribution, cultural representations, mediations, aesthetics, and discourses, this study signals a major initiative to provide a deeper understanding of the intersecting and interdisciplinary approaches that are invoked in the analysis of this popular and influential musical form.

Bridging the Semantic Gap in Image and Video Analysis

Bridging the Semantic Gap in Image and Video Analysis PDF Author: Halina Kwaśnicka
Publisher: Springer
ISBN: 3319738917
Category : Technology & Engineering
Languages : en
Pages : 163
Book Description
This book presents cutting-edge research on various ways to bridge the semantic gap in image and video analysis. The respective chapters address different stages of image processing, revealing that the first step is a future extraction, the second is a segmentation process, the third is object recognition, and the fourth and last involve the semantic interpretation of the image. The semantic gap is a challenging area of research, and describes the difference between low-level features extracted from the image and the high-level semantic meanings that people can derive from the image. The result greatly depends on lower level vision techniques, such as feature selection, segmentation, object recognition, and so on. The use of deep models has freed humans from manually selecting and extracting the set of features. Deep learning does this automatically, developing more abstract features at the successive levels. The book offers a valuable resource for researchers, practitioners, students and professors in Computer Engineering, Computer Science and related fields whose work involves images, video analysis, image interpretation and so on.

Machine Learning for Audio, Image and Video Analysis

Machine Learning for Audio, Image and Video Analysis PDF Author: Francesco Camastra
Publisher: Springer
ISBN: 144716735X
Category : Computers
Languages : en
Pages : 561
Book Description
This second edition focuses on audio, image and video data, the three main types of input that machines deal with when interacting with the real world. A set of appendices provides the reader with self-contained introductions to the mathematical background necessary to read the book. Divided into three main parts, From Perception to Computation introduces methodologies aimed at representing the data in forms suitable for computer processing, especially when it comes to audio and images. Whilst the second part, Machine Learning includes an extensive overview of statistical techniques aimed at addressing three main problems, namely classification (automatically assigning a data sample to one of the classes belonging to a predefined set), clustering (automatically grouping data samples according to the similarity of their properties) and sequence analysis (automatically mapping a sequence of observations into a sequence of human-understandable symbols). The third part Applications shows how the abstract problems defined in the second part underlie technologies capable to perform complex tasks such as the recognition of hand gestures or the transcription of handwritten data. Machine Learning for Audio, Image and Video Analysis is suitable for students to acquire a solid background in machine learning as well as for practitioners to deepen their knowledge of the state-of-the-art. All application chapters are based on publicly available data and free software packages, thus allowing readers to replicate the experiments.

Intelligent Video Event Analysis and Understanding

Intelligent Video Event Analysis and Understanding PDF Author: Jianguo Zhang
Publisher: Springer Science & Business Media
ISBN: 3642175538
Category : Computers
Languages : en
Pages : 252
Book Description
With the vast development of Internet capacity and speed, as well as wide adop- tion of media technologies in people’s daily life, a large amount of videos have been surging, and need to be efficiently processed or organized based on interest. The human visual perception system could, without difficulty, interpret and r- ognize thousands of events in videos, despite high level of video object clutters, different types of scene context, variability of motion scales, appearance changes, occlusions and object interactions. For a computer vision system, it has been be very challenging to achieve automatic video event understanding for decades. Broadly speaking, those challenges include robust detection of events under - tion clutters, event interpretation under complex scenes, multi-level semantic event inference, putting events in context and multiple cameras, event inference from object interactions, etc. In recent years, steady progress has been made towards better models for video event categorisation and recognition, e. g. , from modelling events with bag of spatial temporal features to discovering event context, from detecting events using a single camera to inferring events through a distributed camera network, and from low-level event feature extraction and description to high-level semantic event classification and recognition. Nowadays, text based video retrieval is widely used by commercial search engines. However, it is still very difficult to retrieve or categorise a specific video segment based on their content in a real multimedia system or in surveillance applications.
