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...
Optical Flow Estimation Using Temporally Oversampled Video
Optical flow estimation Motion estimation High speed imaging CMOS image sensor Temporal oversampling
2015/8/12
Recent advances in imaging sensor technology make high frame rate video capture practical. As demonstrated in previous work, this capability can be used to enhance the performance of many image and vi...
