Abstract: The present disclosure provides a method for complex target retrieval from mass videos based on human-machine collaboration. At present, an intelligent system based on machine vision is weak in generalization ability. When an environment changes or a target is shielded or camouflaged, target retrieval from mass videos requires lots of manpower, which is time-consuming and labor-consuming. In the present disclosure, prescreening is performed in a video library using a retrieval model according to a coarse-grained feature of a target, and a candidate target set obtained by screening is made into a brain-eye synergistic rapid serial visual presentation (RSVP) paradigm for presentation for a user. After the user determines the target, a specific feature thereof is input to the retrieval model to realize rapid location and tracking of the target in mass videos.

The precharge circuit is configured to generate, in response to a rising edge and a falling edge of the first sense tracking signal, a precharge signal for precharging data lines.

Abstract: The present disclosure discloses a cross-session brainprint recognition method based on a tensorized spatial-frequency attention network (TSFAN) with domain adaptation. For most of existing multi-source domain adaptation methods, domain gaps between multiple source domains and target domains are individually bridged, but a relationship between domain-invariant features in distribution alignment is ignored. The present disclosure assists performance of a target domain by modeling an important relationship of the domain-invariant features without being affected by a distribution difference between source domains. A new TSFAN is used to combine pairwise source and target and an appropriate common spatial-frequency feature across source domains. Considering of a dimension, the TSFAN is further approximated as a low-rank Tucker format, to enable the TSFAN to adapt to scale linearly in a quantity of domains, and apply the TSFAN to a case of any quantity of sessions.
