Methods and devices for cognitive-based image data analytics in real time
View Patent ↗An invention is disclosed for a real time video analytic processor that embodies algorithms and processing architectures that process a wide variety of sensor images in a fashion that emulates how the human visual path processes and interprets image content. spatial, temporal, and color content of images are analyzed and the salient features of the images determined. These salient features are then compared to the salient features of objects of user interest in order to detect, track, classify, and characterize the activities of the objects. Objects or activities of interest are annotated in the image streams and alerts of critical events are provided to users. Instantiation of the cognitive processing can be accomplished on multi-FPGA and multi-GPU processing hardwares.
1. A real time video analytic image processor which emulates the human visual path comprising:
an imaging sensor configured for capturing and outputting a sequence of image frames to define a video stream;
an edge processor configured to receive the video stream to define an edge processor video stream;
a core processor configured to receive the video stream to define a core processor video stream;
the edge processor and the core processor comprising a hash synchronization function whereby the image frames are synchronized to the edge processor and the core processor using a unique hash identifier;
the edge processor configured to perform a video stream pre-processing function, an analytic function, an analytic metadata output function and a post-processing video compression function to provide an analytic metadata output and a compressed video output;
the core processor configured to receive the analytic metadata output and the compressed video output from the edge processor; and;
the core processor configured to perform a salient feature extraction function by means of a convolution, an object classification and an event detection from the core processor video stream, the analytic metadata output and the compressed video output based on a correlation between an observed object and an object of interest.
