Abstract
Official abstract text for this publication.
Image demosaicing is described, for example, to enable raw image sensor data, where image elements have intensity values in only one of three color channels, to be converted into a color image where image elements have intensity values in three color channels. In various embodiments a trained machine learning component is used to carry out demosaicing optionally in combination with denoising. In some examples the trained machine learning system comprises a cascade of trained regression tree fields. In some examples the machine learning component has been trained using pairs of mosaiced and demosaiced images where the demosaiced images have been obtained by downscaling natural color digital images. For example, the mosaiced images are obtained from the demosaiced images by subsampling according to one of a variety of color filter array patterns.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of image demosaicing comprising: receiving a digital mosaiced image; calculating a demosaiced image from the received image using a trained machine learning system, the demosaiced image being in a linear light-space of a color image processing pipeline, the trained machine learning system having been trained using pairs of mosaiced and demosaiced images, at least one of the pairs comprising at least one of: the mosaiced images having been f…
