1. A processor implemented image processing method, comprising:
receiving an image;
acquiring a target image that includes an object from the image by normalizing a target area including the object based on an information associated with a feature of the object;
calculating an evaluation score by evaluating a quality of the target image; and
detecting the object from the target image based on the evaluation score,
wherein the acquiring of the target image comprises:
performing an approximation of the target area by enlarging or reducing the target area;
performing a scale normalization on the approximated target area based on the information; and
acquiring the target image by performing an illumination normalization on the scaled normalized target area.
