Abstract
Certain aspects of the present disclosure provide techniques for preprocessing, prior to encoding with an external encoder, image data using a preprocessing network comprising a set of inter-connected weights is provided. At the preprocessing network, image data from one or more images is received. The image data is processed using the preprocessing network to generate an output pixel representation for encoding with the external encoder. The weights of the preprocessing network are trained to optimize a combination of at least one quality score indicative of the quality of the output pixel representation and a rate score indicative of the bits required by the external encoder to encode the output pixel representation.
