Shuming Jiao
Dr. Shuming Jiao is currently an assistant professor in Peng Cheng Laboratory, Shenzhen, China. He received his PhD degree in electronic engineering from City University of Hong Kong in 2016. He has been actively engaged in the interdisciplinary investigation between information engineering and optical engineering. His research interest includes holographic three-dimensional imaging and display, single-pixel compressive imaging, optical information processing, optical computing, image processing,information security and machine leaning. He received Hong Kong PhD Fellowship Scheme (2012) and Postdoctoral Fellowship, Pearl River Talent Plan of Guangdong Province (2016). He has published more than 20 papers as the first author in peer-reviewed journals such as Optics Letters, Optics Express and IEEE Transactions on Industrial Informatics. He received Best Paper Award in International Conference on Three-dimensional Image Acquisition and Display Technology and Application 2018 (3DIADT 2018) organized by Chinese Society for Optical Engineering. He received Distinguished Paper Award in International Conferenceon Display Technology 2020 (ICDT 2020) organized by Society for Information Display. He is a reviewer for many international journals and conferences including Optics Letters, Optics Express, Photonics Research, Optica, IEEE Transactions on Industrial Informatics and IEEE International Conference on Computer Vision (ICCV 2021). He is the principal investigator for the research project “Fast target object classification methods in single pixel imaging”(National Natural Science Foundation of China, 61805145). -------------------------------------------------- Potential applications of colorassimilation grid illusion in display technology Optical illusion (or visual illusion)refers to a phenomenon that the image perceived by human vision is different from the physical reality. Human eyes are “cheated” when an optical illusion occurs. Optical illusions receive much attention in vision science, psychology,creative arts and popular culture. But various optical illusions have been seldom investigated for technological applications such as image processing, computervision and optical imaging & display previously. As a unique attempt of combining information technology with optical illusion, we attempt to combine color assimilation (or chromatic assimilation) grid illusion with color display. Inthis illusion, a synthesized image containing a grayscale background and asaturated color line (or point) grid will be perceived as a color image. Many color pixels can be replaced with low-cost grayscale pixels, which is favorable for reducing fabrication cost and compressing data. In addition, the positions of neighboring lines or points in such a pseudo color image can be encoded according to a sequence of bits, which represent embedded external secret data.For the same host image, it appears to be similar when different hidden dataare embedded.
