Abstract:
1. A method for processing an input image securely, comprising: acquiring, in a client, an input image; partitioning the input image into a set of overlapping tiles; transferring the set of overlapping tiles to a server; labeling locally, in the server, motion pixels in each tile that are immediately adjacent to other motions pixels in the tile to generate a set of locally labeled tiles; transferring the set of locally labeled tiles to the client; labeling globally, in the client, the set of locally labeled tiles to generate a list of pairs of unique global labels; transferring the list of pairs of unique global labels to the server; classifying, in the server, the pairs of unique global labels into equivalence classes; transferring the equivalence classes to the client; and relabeling, in the client, the motion pixels according to the equivalence classes to form connected components in the input image.
