Image Number 2 for United States Patent #7822292.
Systems, methods, and apparatus, including computer program products, are provided for forming composite images. In some implementations, a method is provided. The method includes receiving a set of component images for forming a composite image, defining a projection for the set of images transforming each component image into a projected component image, and rendering the projected component images to form the composite image. The rendering of each component image includes decomposing a rotation of the projection into separate rotations for each axis, rotating the component image along a first axis, separately identifying pixel values for each row and each column of the projected component image, and rotating the image along a third axis to form a rendered component image.
