Abstract
Image dewarping includes capturing a source image from a camera, selecting an input row of pixels from the source image, if the input row of pixels comprises a plurality of input pixels in a region of interest in the source image, storing the plurality of input pixels to a memory to generate an input segment of pixels, when a plurality of pixels required to generate an output row of pixels are all stored in the memory, reading from the memory the plurality of pixels corresponding to the output row of pixels, and performing coordinate transformation on the plurality of pixels to generate the output row of pixels, and when coordinate transformation has been completed on the plurality of pixels, releasing from the memory an input segment of pixels of the plurality of input segments of pixels that does not correspond to other output rows of pixels.
