US Patent 10256829 Production of modified image inventories

There are disclosed methods and apparatus for enhancing the image exposure of image inventories. A frame conversion and packaging machine assigns metadata to each frame of a digital video work. It takes objects that have been detected, recognized and assigned metadata to the objects by the frame slicing and packaging machine and enhances the image exposure and assigns new items of metadata to the enhanced-exposure modified images. The frame conversion and packaging machine then generates a cryptographic hash of the enhanced-exposure modified image's digital file. The frame conversion and packaging machine writes the hash to a node of a transaction processing network. Further, there are disclosed methods and apparatus for conversion of monochromatic image inventories to colored image inventories. A frame color-conversion and packaging machine assigns metadata to each frame of a digital video work. It takes objects that have been detected, recognized and assigned metadata to the objects by the frame slicing and packaging machine and converts the original monochromatic images to fully colorized images and assigns new items of metadata to the color-converted images. The frame color-conversion and packaging machine then generates a cryptographic hash of the color-converted modified image's digital file. The frame color-conversion and packaging machine writes the hash to a node of a transaction processing network.
