Generation of synthetic high-elevation digital images from temporal sequences of high-elevation digital images

A system comprising one or more processors and memory storing instructions that, in response to execution by the one or more processors, cause the one or more processors to:

• obtain a first high elevation digital image of a geographic area, wherein the first digital image comprises a plurality of pixels that correspond geographically to a respective plurality of geographic units of the geographic area;
• identify obscured pixels of the first high-elevation digital image that correspond geographically to obscured geographic units of the geographic area that are obscured in the first high elevation digital image by one or more transient obstructions;
• identify, from the first high elevation digital image, a first plurality of pixel clusters, wherein each pixel cluster of the first plurality of pixel clusters comprises unobscured pixels with one or more comparable spectral sub-bands;
• calculate, for the first high elevation digital image, centroids of the first plurality of pixel clusters;
• identify, from a second high elevation digital image of the geographic area, unobscured pixels that correspond geographically to unobscured geographic units that are unobscured by transient obstructions in the second high elevation digital image;
• identify, from the second high elevation digital image, a second plurality of pixel clusters of unobscured pixels, wherein each pixel cluster of the second plurality of pixel clusters comprises pixels with one or more comparable spectral sub-bands;
• calculate, for the second high elevation digital image, centroids of the second plurality of pixel clusters;
• based on the centroids for the first and second high elevation images, calculate replacement pixel data for the obscured pixels of the first high elevation digital image;
• and
• generate a transient-obstruction-free version of the first digital image in which data associated with the one or more obscured pixels is replaced with the replacement pixel data.

At least one non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

• obtain a first high elevation digital image of a geographic area, wherein the first digital image comprises a plurality of pixels that correspond geographically to a respective plurality of geographic units of the geographic area;
• identify obscured pixels of the first high-elevation digital image that correspond geographically to obscured geographic units of the geographic area that are obscured in the first high elevation digital image by one or more transient obstructions;
• identify, from the first high elevation digital image, a first plurality of pixel clusters, wherein each pixel cluster of the first plurality of pixel clusters comprises unobscured pixels with one or more comparable spectral sub-bands;
• calculate, for the first high elevation digital image, centroids of the first plurality of pixel clusters;
• identify, from a second high elevation digital image of the geographic area, unobscured pixels that correspond geographically to unobscured geographic units that are unobscured by transient obstructions in the second high elevation digital image;
• identify, from the second high elevation digital image, a second plurality of pixel clusters of unobscured pixels, wherein each pixel cluster of the second plurality of pixel clusters comprises pixels with one or more comparable spectral sub-bands;
• calculate, for the second high elevation digital image, centroids of the second plurality of pixel clusters;
• based on the centroids for the first and second high elevation images, calculate replacement pixel data for the obscured pixels of the first high elevation digital image;
• and
• generate a transient-obstruction-free version of the first digital image in which data associated with the one or more obscured pixels is replaced with the replacement pixel data.
