Abstract
Embodiments relate to two stage multi-scale processing of an image. A first stage processing circuitry generates an unscaled single color version of the image that undergoes noise reduction before generating a high frequency component of the unscaled single color version. A scaler generates a first downscaled version of the image comprising a plurality of color components. A second stage processing circuitry generates a plurality of sequentially downscaled images based on the first downscaled version. The second stage processing circuitry processes the first downscaled version and the downscaled images to generate a processed version of the first downscaled version. The unscaled single color high frequency component and the processed version of the first downscaled version of the image are merged to generate a processed version of the image.
