US 2017/0323426 A1 · USING DIGITAL IMAGES OF A FIRST TYPE AND A FEATURE SET DICTIONARY TO GENERATE DIGITAL IMAGES OF A SECOND TYPE

Abstract

Systems and methods for generation of images of a particular type from images of a different type are disclosed. In an embodiment, an agricultural intelligence computer system receives a first plurality of images of a first type and a second plurality of images of a second type. The first and second types may refer to variances in resolution, frequency ranges of frequency bands, and/or types of frequency bands used to generate the images. Based on the first plurality of images and the second plurality of images, the agricultural intelligence computer system generates a feature set dictionary comprising mappings from features of the first plurality of images to features of the second plurality of images. When the agricultural intelligence computer system receives a particular image of the first type, the agricultural intelligence computer system uses the received image and the feature set dictionary to generate an image of the second type.

A method comprising:

receiving a first plurality of images at a first image resolution and a second plurality of images at a second image resolution, wherein the first image resolution is lower than the second image resolution;
for each image of the first plurality of images:
transforming the image into a transformed image of the second image resolution;
identifying a plurality of first image pixel sets comprising a plurality of pixels of the transformed image;
identifying, for each first image pixel set, a corresponding second image pixel set of the second plurality of images;
storing each first image pixel set and each corresponding second image pixel set in a database repository of corresponding image pixel sets;
based on the first image pixel sets in the database repository of corresponding image pixel sets, computing a plurality of first image pixel set features, wherein each first image pixel set may be computed as a linear combination of a subset of the plurality of first image pixel set features;
based on the first image pixel set features for each first image pixel set and corresponding second image pixel set, computing a corresponding plurality of second image pixel set features, wherein each first image pixel feature corresponds to a second image pixel set feature of the corresponding plurality of second image pixel set features, and wherein each second image pixel set may be computed as a linear combination of a subset of the corresponding plurality of second image pixel set features and each second image pixel feature of the subset corresponds to a first image pixel feature in the subset of the plurality of first image pixel set features for the first image pixel set that corresponds to the second image pixel set;
storing, in a data record, each first image pixel feature and each corresponding second image pixel feature;
receiving a first particular image at the first image resolution;
transforming the first particular image from the first image resolution to the second image resolution;
identifying a plurality of first particular image pixel sets of the transformed particular image;
for each of the plurality of first particular image pixel sets:
identifying a particular subset of the plurality of first image pixel set features such that the first particular image pixel set may be computed as a linear combination of the particular subset of the plurality of first image pixel set features;
for each first image pixel set feature of the particular subset, identifying a corresponding second image pixel set feature;
computing a second particular image pixel set as a linear combination of the identified corresponding second image pixel set features;
generating and displaying, on a computing device, a second particular image from the second particular image sets.
