A New Proposal for 4-to-2 Optical Encoder Using Nonlinear Photonic Crystal Ring Resonators

In this paper, we proposed an all optical 4-to-2 encoder that has 4 input and 3 output ports. This device generates a 2 bit binary code based on which input port is active. We used nonlinear photonic crystal ring resonators along with optical power splitter for realizing the proposed encoder. In this device the switching rate and area are obtained about 333 GHz and 612µm2 respectively.

RED: Reinforced Encoder-Decoder Networks for Action Anticipation

Action anticipation aims to detect an action before it happens. Many real world applications in robotics and surveillance are related to this predictive capability. Current methods address this problem by first anticipating visual representations of future frames and then categorizing the anticipated representations to actions. However, anticipation is based on a single past frame’s representat...

Encoded LED System for Optical Trackers

Since introducing a hybrid vision-inertial tracker using passive fiducial markers, we have encountered several applications in which the use of encoded LEDs would be preferable to paper fiducials. This includes small-scale applications requiring higher precision, and applications where the size of the target, or the range of viewing angles, or operation in the dark is important. We present a no...

Source Coding With Encoder Side Information

We introduce the idea of distortion side information, which does not directly depend on the source but instead affects the distortion measure. We show that such distortion side information is not only useful at the encoder, but that under certain conditions, knowing it at only the encoder is as good as knowing it at both encoder and decoder, and knowing it at only the decoder is useless. Thus d...
