在人机交互领域取得技术进步需要考虑人类感知系统的能力和局限性。本报告的重点是感知的一个重要机制，视觉选择性注意，这是越来越重要的多媒体应用。我们介绍了视觉注意的概念，并描述了其内在机制。特别是，我们介绍的概念，外显和隐蔽的视觉注意，自下而上和自上而下的处理。还讨论了与建模视觉注意力及其验证使用特设地面实况有关的挑战。在图像和视频处理中的视觉注意力模型的使用的例子。我们强调多媒体传输，图像和视频的重定向和质量评估，医学成像和立体3D图像应用领域。
Making technological advances in the field of human-machine interactions requires that the capabilities and limitations of the human perceptual system are taken into account. The focus of this report is an important mechanism of perception, visual selective attention, which is becoming more and more important for multimedia applications. We introduce the concept of visual attention and describe its underlying mechanisms. In particular, we introduce the concepts of overt and covert visual attention, and of bottom-up and top-down processing. Challenges related to modeling visual attention and their validation using ad hoc ground truth are also discussed. Examples of the usage of visual attention models in image and video processing are presented. We emphasize multimedia delivery, retargeting and quality assessment of image and video, medical imaging, and the field of stereoscopic 3D images applications.
