The core component of … WebFor most applications, electrical pumping is preferable to optical pumping. Electrical pumping is accomplished by placing the optical gain region (the semiconductor we wish to invert) in the middle of a p-n junction diode. This is diagrammed below. When forward biased, the diode will inject electrons from the n-side into the gain region, and ...
WebMar 26, 2024 · We introduce Recurrent All-Pairs Field Transforms (RAFT), a new deep network architecture for optical flow. RAFT extracts per-pixel features, builds multi-scale 4D correlation volumes for all pairs of pixels, and iteratively updates a flow field through a recurrent unit that performs lookups on the correlation volumes. RAFT achieves state-of … WebFlowFormer introduces a transformer architecture into optical flow estimation and achieves state-of-the-art performance. The core component of FlowFormer is the transformer-based cost-volume encoder.
