Abstract: Systems, methods, and non-transitory media are provided for frequency domain edge enhancement of multi-exposure high dynamic range (HDR) images. An example method can include determining an alignment between an HDR frame and a frame having an exposure time above a threshold; adjusting the frame based on the alignment; determining a gradient estimation map representing differences between image blocks in the HDR frame and image blocks in the frame; and generating, based on the gradient estimation map, a merged frame that includes a combination of at least some image data from the HDR frame and at least some image data from the frame.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths of fields. A method of processing image data includes determining, based on a depth map of a previously captured image, a first distance to a first object and a second distance to a second object; identifying a focal point of a camera lens at least in part using the first distance and the second distance; capturing an image using the focal point as a basis for the capture, the image including a first region corresponding to the first object and a second region corresponding to the second object; and generating a second image from the image at least in part by enhancing at least one of the first region or the second region using a point spread function (PSF).

Abstract: Techniques and systems are provided for processing image data. A first image having a first resolution can be obtained. In some aspects, the first image is generated based on a pixel binning process. A second image can be obtained having a second resolution that is greater than the first resolution. In some aspects, the second image is generated based on a remosaicing process. One or more weight maps can be generated based on characteristics determined based on pixels of the first image, pixels of the second image, or pixels of both the first image and the second image. A fused image can be generated based on the one or more weight maps that includes a first set of pixels from the first image and a second set of pixels from the second image.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images. A method of processing image data includes determining a first region of interest (ROI) in an image. The first ROI is associated with a first object. The method can include determining one or more image characteristics of the first ROI. The method can further include determining whether to perform an upsampling process on image data in the first ROI based on the one or more image characteristics of the first ROI.

Abstract: Systems and techniques are provided for processing image data. According to some aspects, a process can include obtaining a frame captured using an image sensor of a device. The process can include detecting an orientation of the device using a position sensor. The process can further include determining, based on the orientation, a transform to be applied to a region of interest in the frame. The process can include applying the transform to the region of interest. The process can further include providing the transformed region of interest to the object detection algorithm.
