  • Patent number: 9934437
    Abstract: Described is a system for collision detection. The system divides an image in a sequence of images into multiple sub-fields comprising complementary visual sub-fields. For each visual sub-field, motion is detected in a direction corresponding to the visual sub-field using a spiking Reichardt detector with a spiking neural network. Motion in a direction complementary to the visual sub-field is also detected using the spiking Reichardt detector. Outputs of the spiking Reichardt detector, comprising data corresponding to one direction of movement from two complementary visual sub-fields, are processed using a movement detector. Based on the output of the movement detector, an impending collision is signaled.

  • Patent number: 9740949
    Abstract: Described is a system for detecting objects of interest in imagery. The system is configured to receive an input video and generate an attention map. The attention map represents features found in the input video that represent potential objects-of-interest (OI). An eye-fixation map is generated based on a subject's eye fixations. The eye-fixation map also represents features found in the input video that are potential OI. A brain-enhanced synergistic attention map is generated by fusing the attention map with the eye-fixation map. The potential OI in the brain-enhanced synergistic attention map are scored, with scores that cross a predetermined threshold being used to designate potential OI as actual or final OI.

  • Patent number: 9671493
    Abstract: Described is system for optimizing visual inspection of radar targets. The system detects radar hits with a radar system comprising radar and a radar-cued camera. The camera has a current state comprising a current slew position and a current zoom level. The radar hits are stored, and a set of metrics are determined for each radar hit. A track value (TV) metric is determined that combines the set of metrics for each zoom level of the camera. The camera sends a set of commands based on the TV metric, such that the camera slews from the current state to a new state. The new state is a position of a radar hit with the largest TV metric and a corresponding zoom level. Given the new state, an image is captured and processed to generate captured tracks. The current state of the camera is updated to reflect the new state.

  • Patent number: 9489732
    Abstract: Described is a system for improved electroencephalograph (EEG) rapid serial visual presentation (RSVP) target stimuli detection through visual attention distractor insertion. A first RSVP sequence is created comprising a set of image chips. The image chips are a combination of target images containing target events and non-target images containing comment events. A number of visual attention distractors to optimize target event detection is determined, and the determined number of visual attention distractors is inserted into the first RSVP sequence to generate a second RSVP sequence. The second RSVP sequence is reordered to generate a third RSVP sequence. The third RSVP sequence is presented to a user, and an EEG signal is received from the user. Finally, the EEG signal is decoded to identify a true target event via a P300 detection in the EEG signal.

  • Patent number: 9269027
    Abstract: Described is a system for optimizing rapid serial visual presentation (RSVP). A similarity metric is computed for RSVP images, and the images are sequenced according to the similarity metrics. The sequenced images are presented to a user, and neural signals are received to detect a P300 signal. A neural score for each image is computed, and the system is optimized to model the neural scores. The images are resequenced according a predictive model to output a sequence prediction which does not cause a false P300 signal. Additionally, the present invention describes computing a set of motion surprise maps from image chips. The image chips are labeled as static or moving and prepared into RSVP datasets. Neural signals are recorded in response to the RSVP datasets, and an EEG score is computed from the neural signals. Each image chip is then classified as containing or not containing an item of interest.

  • Patent number: 9196053
    Abstract: Described is a system for object detection from dynamic visual imagery. Video imagery is received as input, and the system processes each frame to detect a motion region exhibiting unexpected motion representing a moving object. Object-based feature extraction is applied to each frame containing a detection motion region. Each frame is then divided into feature-consistent regions. A motion seeded region (MSR) is identified in each frame containing a detected motion region, where the MSR corresponds to a spatial location of the detected motion region. Similar feature-consistent regions that are adjacent to and include the MSR are joined to compute a boundary around the plurality of similar feature-consistent regions. Finally, the system outputs a computed boundary surrounding an object in the detected motion region.
