Abstract:
1. Within an image acquisition system comprising a non-linear, wide-angled lens and an imaging sensor, a method of enhancing a scene containing one or more off-center peripheral regions, the method comprising: acquiring an initial distorted image with a large field of view, including using a non-linear, wide-angled lens and imaging sensor; determining and extracting an off-center region of interest (hereinafter “ROI”) within said image; applying geometric correction to reconstruct the off-center ROI into an approximately rectangular frame of reference as a first reconstructed ROI; determining a quality of reconstructed pixels within said first reconstructed ROI; applying object tracking to one or more regions within the first reconstructed ROI respectively adapted to one or more local reconstructed pixel qualities within the one or more regions; determining if undetected objects below a predetermined size threshold are likely to exist in one or more reduced quality regions of the first reconstructed ROI; responsive to said determining if undetected objects exist, acquiring one or more additional initially distorted images, and extracting and reconstructing matching additional ROIs to combine with reduced quality pixels of said first reconstructed ROI to provide one or more enhanced ROIs; performing a further action based on a value of a parameter of an object within the one or more enhanced ROIs.
