1. An image frame extraction apparatus, comprising:
at least one memory configured to store program code; and
electric circuitry including at least one of a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), and at least one processor, the at least one processor being configured to read and operate according to the program code, the electronic circuitry configured to:
acquire a video image;
extract features of each of a plurality of image frames of the acquired video image;
analyze the extracted features of each of the plurality of image frames, and extract candidates of a representative frame from the plurality of image frames; and
for each of the extracted candidates of the representative frame, calculate a displacement in a shape space of a pose of an object in the image frame with respect to a reference pose, and select the representative frame from the candidates of the representative frame based on the calculated displacement in the shape space.
