Creative Tasks

From cooking kits to home improvement shows, consumers are increasingly seeking out products that are designed to help them be creative. In this research, the authors examine why consumers participate in creative activities and under what conditions these experiences are the most enjoyable. A qualitative study explores the diverse motivations for undertaking creative tasks and identifies the role of constraints in such endeavors. Then, the authors conduct two experimental studies to understand the importance of constraints (e.g., instructional guidance, target outcomes) in facilitating a balance between perceived competence and autonomy for consumers involved in a creative task. When consumers engage in creative activities with a sense of both autonomy and competence, they enjoy the experience more. The authors discuss implications for managers and provide opportunities for further research.

Watermarking is a technique of hiding a message about a work of media within that work itself in· the purpose of protecting the digital information against illegal duplication and manipulation. The objectives of this study are to analyze the robustness and distortion performance of watermarking system and to explore watermarking schemes which balance the robustness-distortion tradeoff optimally. In this thesis, We present a detector algorithm to adaptively extract spread spectrum watermark by filtering the watermarked images with Wiener filter. Two optimization algorithms for quantization watermarking are proposed. First one optimizes uniform quantization based look-up table embedding which minimizes watermarking distortion. Secondly, we analyze the robustness-distortion tradeoff and formulate the robustness-distortion tradeoff into a Lagrangian function. Hence optimal quantizers for watermarking subject to given robustness or fidelity constraint are achieved.
