Assignee: ROBERT BOSCH GMBH
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 17:
18. A vehicle configured to utilize an image quantization machine-learning model, the vehicle comprising:
a sensor configured to capture an image; and
one or more processors communicatively coupled to the sensor and to memory, wherein the one or more processors are configured to utilize an image quantization machine-learning model to process the image, wherein the image quantization machine-learning model is trained according to the following steps:
receiving a plurality of input images, wherein each input image includes a plurality of pixels;
assigning each pixel a new pixel color via an image-to-image machine-learning model;
converting each new pixel color to one of a fixed number of colors via a mixer model to produce a plurality of quantized images, each quantized image corresponding to one of the input images;
computing a loss function associated with an alignment of each input image with its corresponding quantized image via a pre-trained reference model;
updating one or more parameters of the image-to-image machine-learning model and the mixer model based on the loss function; and
outputting a trained image quantization machine-learning system utilizing the updated parameters and upon convergence.
