Temporal Psychovisual Modulation: a new paradigm of image formation

本研究是关于一种新的图像形成范式，称为时间心理视觉调制（TPVM），这是申请人最近发明的。TPVM是基于人类视觉的心理物理学、光电子学和数学建模的一种新的相互作用。为了形成一类目标图像，高速光电显示器在可见光谱中广播一组所谓的原子帧，这些原子帧是通过非负矩阵分解计算的图像信号的基础。通过适当调制原子框架的光场的显示同步观看设备，不同的用户可以依靠自己的认知能力暂时融合调制的原子框架来感知自我意图的图像。TPVM图像形成范式具有独特而重要的功能：在同一物理显示介质上同时进行多个无干扰的视觉展示，这是现有显示技术无法实现的。这个功能使TPVM可以用于许多新的应用程序，包括科学/医学可视化、虚拟现实、信息安全、进行与视觉相关的科学实验的工具、消费电子产品等。

This research is on a new paradigm of image formation, called temporal psychovisual modulation (TPVM), which is recently invented by the applicant. TPVM is based on a novel interplay of psychophysics, optoelectronics and mathematical modeling of human vision. To form a class of target images, a high-speed optoelectronic display broadcasts, in visible spectrum, a set of so-called atom frames that are the bases of the image signals computed by non-negative matrix factorization. Through display-synchronized viewing devices that appropriately modulate the light fields of the atom frames, different users can perceive self-intended images by relying on their own cognitive faculty to temporally fuse the modulated atom frames. The TPVM image formation paradigm has a unique and important functionality: concurrent multiple interference-free visual exhibitions on a same physical display medium, which is impossible with existing display technologies. This functionality lends TPVM to many new applications, including scientific/medical visualization, virtual reality, information security, tools for conducting vision-related scientific experiments, consumer electronics, and etc. The applicant is nominated by McMaster University for Discovery Accelerator Supplements to capitalize on the above exciting research opportunity.
