摘要： A method and system for blending images into a single image. Initially two images of a view are selected, wherein the images have overlapping content of the view. The images can differ from each other in such characteristics as time, camera location, camera settings, and lighting. The images are divided into strips along a common plane in a region of each image where the images overlap. A strip from each image is selected where the images are a close match. Pixel by pixel difference values between the two strips are calculated, and a cut line is determined where the differences between the two strips are minimized. Each image is cut along the corresponding cut line, and the cut images are blended together to form a single image of the view. The blended single image can be further processed by warping the image along the cut line to provide for a smoother fit between the two images.

摘要： A method performed by a processing system. The method includes receiving a sequence of frames, each frame comprising a sequence of at least two images, each image at a different image position in the sequence and each pair of adjacent images having an overlap region. A local alignment value is determined for the images of each pair of adjacent image positions of each frame based on minimizing a difference of a desired parameter between the images in the overlap region. Global alignment values are determined for all images at corresponding pairs of adjacent image positions of each frame based on the local alignment values for the images at the corresponding pair of adjacent image positions of each frame. Each global alignment value is applied to at least one image of the images of the corresponding pair of adjacent image positions of each frame.

摘要： The present disclosure generally relates to systems and methods for image data processing. In certain embodiments, an image processing pipeline may compute noise statistics associated with image data by receiving a frame of the image data having a plurality of pixels. The image processing pipeline may then identify a plurality of portions of the frame of the image data such that each portion of the plurality of portions has a flat surface. The image processing pipeline may then calculate a plurality of gradients for each portion of the plurality of portions, determine one or more dominant gradient orientations for each portion of the plurality of portions, and generate a histogram that represents a plurality of dominant gradient orientations that corresponds to the plurality of portions. After generating the histogram, the image processing pipeline may store the histogram, which may represent the noise statistics, in a memory.

摘要： Image sensors have finite ranges of illuminance that may be captured. When the sensors for particular pixels receive an amount of light exceeding these finite ranges, the pixel values clip to the maximum pixel value. Systems and methods for estimating pixel values that are clipped or near clipping are provided. In one example, a method for processing image data includes determining that a first channel of the image data is saturated or near saturation. The method further includes computing a highlight recovery value for the first channel based upon alternative channels in the image data that are not saturated or near saturation. The highlight recovery value is applied to the first channel.

摘要： Systems and methods for correcting intensity drop-offs due to geometric properties of lenses are provided. In one example, a method includes receiving an input pixel of the image data, the image data acquired using an image sensor. A color component of the input pixel is determined. A gain grid is determined by pointing to the gain grid in external memory. Each of the plurality of grid points is associated with a lens shading gain selected based upon the color of the input pixel. A nearest set of grid points that enclose the input pixel is identified. Further, a lens shading gain is determined by interpolating the lens shading gains associated with each of the set of grid points and is applied to the input pixel.
