New PhD student in the Colorlab
Xingbo Wang has just started his PhD in the Colorlab. In the next three years he will focus on filter arrays for multispectral acquisition. Xingbo has a background in research, media, and engeneering, and in addition he completed his masters in the Color in Informatics and Media Technology (CIMET) programme, in which the Colorlab is one of the partners.
We welcome Xingbo to the Colorlab, and we are looking forward to benefiting from his knowledge and effort.
Short biography
:
Having followed several career paths within research, media and engineering, Xingbo determined to resume his education, in relentless pursuit of knowledge about colour and imaging science. He started his PhD with the Colorlab soon after obtaining his MSc degree in Color in Informatics and Media Technology from an Erasmus Mundus master programme of the same name. An SMPTE member, he always has a passionate interest in the application of image acquisition to the realm of motion picture and television.
Thesis title:
Filter array for multispectral acquisition: Design of spectral filters, spatial arrangement, demosaicing, and application to biometrics
Introducion to the thesis work:
Recent improvements in nanotechnologies permit the design of accurate spectral filters, at the level of a sub pixel, directly printed on a silicon layer. This new technology permits the design of multispectral imaging devices of reduced size and lower cost that enable a multispectral acquisition with a single shot at the cost of spatial resolution.
The purpose of this thesis is first to evaluate if and how SFA (Spectral Filter Array) based multispectral imaging devices could be used with the benefits to biometrics and security. A second aspect would be to propose and develop solutions based on SFA. The research work includes the investigation of the possibilities and the optimization of the combination of selected spectral filters, their number, their spatial arrangement and interpolation methods, considering different indicators mostly based on biometric applications.
