20220038620 · 2022-02-03 ·

Methods and systems for generating image capture device parameter suggestions that would produce an image in, or closer to, a desired aesthetic style. In particular, the systems and methods described herein include pattern recognition techniques which are utilized to extract visual features from a set of images, those features defining an aesthetic style. The set of images comprise exemplars of said aesthetic style as well as images representing a plurality of variations in image capture parameters. An algorithm is trained to discriminate between exemplar and variation images based on their extracted visual features. When the system is presented with an input image the same visual features are extracted from it and are compared to the characteristic visual features of the exemplar and variation images with the trained discriminator algorithm. The similarity of the input image to exemplar and variation images are used to generate image capture device parameter suggestions.

DOMAIN ADAPTATION BY MULTI-NOISING STACKED MARGINALIZED DENOISING ENCODERS

A machine learning method operates on training instances from a plurality of domains including one or more source domains and a target domain. Each training instance is represented by values for a set of features. Domain adaptation is performed using stacked marginalized denoising autoencoding (mSDA) operating on the training instances to generate a stack of domain adaptation transform layers. Each iteration of the domain adaptation includes corrupting the training instances in accord with feature corruption probabilities that are non-uniform over at least one of the set of features and the domains. A classifier is learned on the training instances transformed using the stack of domain adaptation transform layers. Thereafter, a label prediction is generated for an input instance from the target domain represented by values for the set of features by applying the classifier to the input instance transformed using the stack of domain adaptation transform domains.
