1. An electronic apparatus, comprising:
a memory configured to store a reference image set including a plurality of reference images for a plurality of body parts; and
a processor communicatively connected to the memory, and configured to:
equally divide an input image capturing a human body into a preset number of segmented images;
determine a first segmented image having a highest priority for a first body part of the plurality of body parts from the preset number of segmented images;
determine an average value of all of pixels of the input image as a reference value;
compare each of pixel values of first pixels of the first segmented image with the reference value;
process the first segmented image by resetting each of the pixel values of the first pixels of the first segmented image, which is smaller than the reference value, to 0 and resetting each of the pixel values of the first pixels of the first segmented image, which is equal to or larger than the reference value, to a difference value between each of the pixel values and the reference value;
select a first reference image for the first body part from the reference image set;
determine whether or not a partial region matching the first reference image exists in the first segmented image processed by the reference value, based on calculation results for the first pixels of the first segmented image processed by the reference value and second pixels of the first reference image corresponding to the first pixels;
upon determining that the partial region exists, determine a bone age grade of the first body part based on the first reference image; and
determine a bone age of the human body based on the bone age grade.
