MODELING TREES FOR VIRTUAL SINGAPORE: FROM DATA ACQUISITION TO CITYGML MODELS
LiDAR virtual city tree extraction and quantification procedural tree modeling
2018/9/12
Singapore, branded as a “City in a Garden”, has a long standing commitment to green the nation, one which has resulted in trees becoming an integral component of the urban environment. Similarly for i...
Modeling and Simulation of Integrated Luminescence Detection Platforms
Luminescence probes Modeling CMOS sensor post-processing
2015/8/17
We developed a simulation model of an integrated CMOS-based imaging platform for use with bioluminescent DNA microarrays. We formulate the complete kinetic model of ATP based assays and luciferase lab...
Modeling and Estimation of FPN Components in CMOS Image Sensors
CMOS image sensor fixed pattern noise nonuniformity image sensor characterization
2015/8/14
Fixed pattern noise (FPN) for a CCD sensor is modeled as a sample of a spatial white noise process. This model is,however, not adequate for characterizing FPN in CMOS sensors, since the readout circui...
Skywave signals are an inherent part of low frequency transmissions such as Loran.Unfortunately for navigation users, skywave signals are a source of interference to the Loran groundwave signal used f...
