Google patents method to expand image training data by recoloring
Google describes a technique for creating more training data for image processing models. It works by turning images into grayscale and then using separate colorization models to add different colors back in, creating new variations of the original pictures.
In the filing’s own words
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating, using one or more coloraF_ization models, an augmented set of training data. One of the methods includes receiving a plurality of training examples for training an image processing model, each training example comprising an image and a corresponding ground-truth output for the image; generating, for each image, a respective grayscale image; generating, for each respective grayscale image, one or more recolored images using one or more colorization models; and generating an augmented set of training data for training the image processing model that comprises a plurality of additional training examples.
What exactly they claim (claim 1)
1. A computer-implemented method comprising: receiving a plurality of training examples for training an image processing model, each training example comprising a synthetic image and a corresponding ground-truth output for the synthetic image; generating, for each synthetic image, a respective grayscale image; generating, for each respective grayscale image, one or more recolored images using one or more colorization models, wherein each colorization model is different than the image processing model; and generating an augmented set of training data for training the image processing model that comprises a plurality of additional training examples, each additional training example comprising a respective recolored image generated from a respective synthetic image and the corresponding ground-truth output for the respective synthetic image.
