Efficient and effective handling of video documents depends on the availability of indexes. Manual indexing is unfeasible for large video collections. Effective indexing requires a multimodal approach in which either the most appropriate modality is selected or the different modalities are used in collaborative fashion. In this paper we focus on the similarities and differences between the moda...

This paper describes the initial efforts to explore the benefits of OO development by describing a framework for categorizing benefits based on phases of system development and by level of analysis. The level of analysis of OO benefits can be the enterprise level, the project level, and the individual developer level. The framework was tested by conducting structured interviews with information...

This paper presents a survey of human action recognition approaches based on visual data recorded from a single video camera. We propose an organizing framework which puts in evidence the evolution of the area, with techniques moving from heavily constrained motion capture scenarios towards more challenging, realistic, “in the wild” videos. The proposed organization is based on the representati...

Categorizing free-hand human sketches has profound implications in applications such as human computer interaction and image retrieval. The task is non-trivial due to the iconic nature of sketches, signified by large variances in both appearance and structure when compared with photographs. Prior works often utilize off-the-shelf low-level features and assume the availability of a large trainin...

This article provides an innovative meta-framework comprising strategies designed to guide qualitative data collection in the 21st century. We present a meta-framework comprising strategies for collecting data from interviews, focus groups, observations, and documents/material culture. We present a template for collecting nonverbal data during interviews and discuss the concept of debriefing th...

Scholars have suggested that design thinking (DT) should form an integral part of the new product development (NPD) process. However, contribution DT to NPD over past years is yet be synthesized. In this article, we develop a conceptual framework categorizing how contributes NPD, and present map visualize research in area has evolved 20 years. A systematic analysis 89 journal papers published b...

Consuming services online is an exponentially growing trend within different industries. A robust online authentication solution to these services is a critical requirement for establishing trust between end users and service providers. Currently, the shortcomings of password based authentication solutions are well recognized.Hence, many alternative strong authentication solutions are being ado...

Efficient and effective handling of video documents depends on the availability of indexes. Manual indexing is unfeasible for large video collections. Efficient, single modality based, video indexing methods have appeared in literature. Effective indexing, however, requires a multimodal approach in which either the most appropriate modality is selected or the different modalities are used in co...
