1. A system for selective retention and editing of images, the system comprising: a continuous capture mobile image capture device designed for resource efficiency, the mobile image capture device comprising a network interface, a power source, an image sensor, at least one processor, and a memory that stores at least one neural network usable to determine a desirability of a scene depicted by an image, the memory comprising at least a temporary image buffer and a non-volatile memory, the mobile image capture device operable to: capture a first image that depicts a scene; maintain a first copy of the first image in the temporary image buffer; input the first image into the at least one neural network; receive at least one descriptor of the desirability of the scene depicted by the first image as an output of the at least one neural network; determine, based at least in part on the at least one descriptor of the desirability of the scene of the first image, whether to store a second copy of the first image in the non-volatile memory of the mobile image capture device or to discard the first copy of the first image from the temporary image buffer without storing a second copy of the first image in the non-volatile memory; and transmit at least one of a plurality of images stored in the non-volatile memory to a user computing device.
