It is well recognized that air quality inference is of great importance for environmental protection. However, due to the limited monitoring stations and various impact factors, e.g., meteorology, traffic volume and human mobility, inference of air quality index (AQI) could be a difficult task. Recently, with the development of new ways for collecting and integrating urban, mobile, and public service...
Aesthetic photo retouching is the process of removing some given objects in a real photo deliberately and producing a complete, natural-looking pseudo-image automatically. The paper presents an aesthetic photo retouching method with a proposed image inpainting algorithm, which restores large missing regions in an image based on morphological erosion and structure feature replication. As for aesthetic...
A novel beam splitter is designed on the basis of the coupling characteristics between the waveguide and ring resonator. By Simply adjusting the effective refractive of the coupling rods, uniform or free splitting can be achieved. The characteristics of the structure are investigated by FDTD and PWE methods.
