Blind Detection and Compensation of Camera Lens Geometric Distortions
This paper presents a blind detection and compensation technique for camera
lens geometric distortions. The lens distortion introduces higher-order
correlations in the frequency domain and in turn it can be detected using
higher-order spectral analysis tools without assuming any specific calibration
target. The existing blind lens distortion removal method only considered a
single-coefficient radial distortion model. In this paper, two coefficients are
considered to model approximately the geometric distortion. All the models
considered have analytical closed-form inverse formulae.Comment: 6 pages, 4 figures, 2 table

Efficient Convolutional Neural Network for FMCW Radar Based Hand Gesture Recognition
FMCW radar could detect object's range, speed and Angleof-Arrival, advantages
are robust to bad weather, good range resolution, and good speed resolution. In
this paper, we consider the FMCW radar as a novel interacting interface on
laptop. We merge sequences of object's range, speed, azimuth information into
single input, then feed to a convolution neural network to learn spatial and
temporal patterns. Our model achieved 96% accuracy on test set and real-time
test.Comment: Poster in Ubicomp 201
