Abstract: Embodiments relate to circuitry for warping image pyramids for image fusion. An image fusion circuit receives captured images, and generates image pyramids corresponding to the received images to be used for image fusion. A warping circuit warps the first image pyramid based upon one or more warping parameters to align the first image pyramid to the second image pyramid. The warping circuit is a multi-scale warping circuit configured to warp each level of the first image pyramid, using a first warping engine that warps a base level of the image pyramid, and at least one addition warping engine that warps a plurality of scaled levels of the image pyramid in parallel with the first warping engine.

Abstract: Blocks of pixels from a video frame may be encoded in a block processing pipeline using wavefront ordering, e.g. according to knight's order. Each of the encoded blocks may be written to a particular one of multiple buffers such that the blocks written to each of the buffers represent consecutive blocks of the frame in scan order. Stitching information may be written to the buffers at the end of each row. A stitcher may read the rows from the buffers in order and generate a scan order output stream for the frame. The stitcher component may read the stitching information at the end of each row and apply the stitching information to one or more blocks at the beginning of a next row to stitch the next row to the previous row. Stitching may involve modifying pixel(s) of the blocks and/or modifying metadata for the blocks.

Abstract translation: 来自视频帧的像素块可以使用波前排序在块处理流水线中进行编码，例如， 根据骑士的命令。 每个编码块可被写入多个缓冲器中的特定一个缓冲器，使得写入每个缓冲器的块以扫描顺序表示帧的连续块。 拼接信息可以写入每行末尾的缓冲区。 拼接器可以按顺序从缓冲器中读取行，并为该帧生成扫描顺序输出流。 缝合器部件可以读取每行末端的缝合信息，并将缝合信息应用于下一行开始处的一个或多个块，以将下一行缝合到前一行。 缝合可以涉及修改块的像素和/或修改块的元数据。
