Abstract: Systems and techniques are provided for conserving resources when performing motion estimation. An example process can include determining, based on an input image and a reference image, motion vectors identifying motion between the input image and the reference image; determining whether the motion indicated by the motion vectors is below a first threshold; based on a determination that the motion indicated by the motion vectors is below the first threshold, refraining from determining a local motion between the input image and the reference image; determining a transform matrix based on the motion vectors and without using a local motion between the input image and the reference image; and adjusting the input image based on the transform matrix.

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: This disclosure provides systems, methods, and devices for image signal processing that support improved correction of motion artifacts within image frames. In a first aspect, a method of image processing includes receiving a first image frame and a second image frame, determining a motion map indicating motion of objects within the first and second image frames. Additionally, motion hotspots may be identified within the second image frame based on the motion map. A temporal filtering process may be applied to portions of the second image frame located within motion hotspots to generate a corrected image frame. Other aspects and features are also claimed and described.
