Abstract: This disclosure provides systems, methods, and devices for vehicle driving assistance systems that support image processing. In a first aspect, a method of image processing includes receiving first image data from a first image sensor of a first camera, receiving second image data from a second image sensor of a second camera, wherein a first field of view of the second image data overlaps at least a portion of a second field of view of the first image data, generating, based on the first image data and the second image data, a bird's eye view composite image, detecting one or more holes in the bird's eye view composite image, and filling the one or more holes in the bird's eye view composite image using one or more rays of the first camera. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for vehicle driving assistance systems that support image processing. In a first aspect, a method of image processing includes receiving image data comprising a first image frame and a second image frame; determining a global motion model corresponding to the first image frame and the second image frame; warping the first image frame based on the global motion model to determine a warped first image frame; and determining a local flow based on the warped first image frame and the second image frame. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for global motion modeling. Embodiments include receiving a first image and a second image from a camera attached to a moving object. Embodiments include identifying a pixel in the first image. Embodiments include determining, based on one or more parameters associated with the camera, a vector representing a range of locations in which a real-world point corresponding to the pixel is likely to be found in the second image, wherein the parameters associated with the camera comprise: a first parameter related to a location of the camera relative to a ground surface; a second parameter related to motion of the moving object; and a third parameter related to an orientation of the camera relative to the ground surface. Embodiments include determining, using the vector, a location of the real-world point in the second image.
