A traditional ultrafast fibre laser has a constant cavity length that is independent of the pulse wavelength. The investigation of distributed ultrafast (DUF) lasers is conceptually and technically challenging and of great interest because the laser cavity length and fundamental cavity frequency are changeable based on the wavelength. Here, we propose and demonstrate a DUF fibre laser based on ...

We introduce a method for improving facial attribute predictions using other attributes. In the domain of face recognition and verification, attributes are high-level descriptions of face images. Attributes are very useful for identification as well as image search as they provide easily understandable descriptions of faces, rather than most other image descriptors (i.e. HOG, LBP, and SIFT). A ...

QR code(Quick Response Code) is a popular two-dimensional matrix that randomly consists of black and white square modules. While the appearance of QR codes are often visually unpleasant, it leads to the increasing demand for the aesthetic QR codes. However, it may turn out to be unreadable if changes to the modules of the QR code are inadequate. Therefore, to resolve this conflict, we propose a...
