Abstract: A gripping device comprising: a base; at least one pair of extendable linkages connected at a proximal end to the base; each extendable linkage having a gripping finger extending from a distal end of the extendable linkage; wherein the extendable linkages are arranged to extend or retract from the base so as to increase a radial distance between the gripping fingers.

Abstract: A method and an apparatus for generating cover images for steganography are provided. The steganographic framework is designed based on an image generation system. The apparatus may encode a message to obtain a binary sequence. The apparatus may obtain a plurality of binary segments of a particular length based on the binary sequence. For each binary segment of the plurality of binary segments, the apparatus may select an image of a semantic content (e.g., a numeral digit) from a dictionary of images of random semantic contents (e.g., random numeral digits) based on the binary segment. The apparatus may combine the selected images to form at least a portion of a cover image denoting a combination of the semantic contents of the selected images (e.g., a plurality of numeral digits).
