1. A system for scene change detection, the system comprising: one or more processors and a memory, the memory having instructions encoded thereon for causing the one or more processors to perform operations of: receiving an input image from a video stream, the input image being a current frame in the video stream; color conditioning the input image to generate a color conditioned image; using a window to segment the input image into a plurality boxes; extracting descriptors from each box of the color conditioned image; identifying differences in the descriptors between a current frame and past frames; attenuating the differences to generate a descriptor attenuation factor α i ; generating initial scores for each box based on the descriptor attenuation factor α i ; filtering the initial scores to generate a set of conspicuity scores for each box, the set of conspicuity scores being reflective of a conspicuity of each box in the image; and presenting to a user or providing for further processing the boxes having conspicuity scores that exceed a predetermined threshold.
