Learned image transformation methods and systems in graphics rendering

A frame transformation pipeline module configured to transform rendered frames in a graphics processing system to obtain enhanced frames comprising one or more desired characteristics exhibited in a set of target images, the frame transformation pipeline module comprising logic configured to:

• select a plurality of trained shaders, each trained shader defined by a parametrized mathematical function arranged to replicate a particular visual characteristic, wherein, for each trained shader of the plurality of trained shaders:
• parameters of the parametrized mathematical function have been derived in dependence on a set of target images in order that the trained shader is arranged to impose, when applied to a frame, its respective particular visual characteristic in dependence on an extent to which the particular visual characteristic is exhibited in the set of target images, the parameters of the parametrized mathematical function thereby being trained and predetermined parameters;
• combine the plurality of trained shaders to form a frame transformation pipeline;
• obtain one or more rendered frames;
• apply each trained shader of the frame transformation pipeline to at least a portion of each of the one or more rendered frames to obtain one or more enhanced frames;
• and
• output for display each of the one or more enhanced frames, wherein the enhanced frames exhibit the visual characteristics of the set of target images.
