Claim 8:
9. A system for performing image quantization via machine learning, the system comprising:
an input interface configured to receive input images from a sensor; and
one or more processors in communication with the input interface, the one or more processors programmed to:
(i) utilize an image-to-image machine-learning model to assign each pixel of the input images a new pixel color,
(ii) utilize a mixer model to map each new pixel color to one of a fixed number of colors to produce a quantized image corresponding to each input image,
(iii) align each input image with its corresponding quantized image via a pre-trained reference model to determine a loss function,
(iv) backpropogate the loss function into the image-to-image machine learning model and the mixer model, and
(v) output a trained image-to-image machine learning model and a trained mixer model after repeating (i)-(iv) until convergence.
