Abstract
An image processing method implemented by a processor includes receiving an image, acquiring a target image that includes an object from the image, 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.
Claims20
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.

An image processing apparatus comprising:
- a receiver configured to receive an image;
- and
- a controller configured to detect an object included in the image by evaluating a quality of the image, the controller comprising:
- a target image acquirer configured to acquire a target image that includes the object from the image by normalizing a target area including the object based on an information associated with a feature of the object;
- a quality evaluator configured to calculate an evaluation score by evaluating a quality of the target image;
- and
- an object detector configured to detect the object from the target image based on the evaluation score,
- wherein the target image acquirer comprises a normalizer configured to:
- perform an approximation by enlarging or reducing the target area,
- perform a scale normalization on the approximated target area based on the information, and

An image processing method implemented by a processor, comprising:
- receiving an image in a plurality of frames;
- acquiring a target image that includes an object from the image in a first frame of the plurality of frames 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 in the first frame;
- and
- suspending a detection of the object from the target image in the first frame in response to the evaluation score being less than a detection reference score and performing the detection of the object in response to the evaluation score being greater than or equal to the detection reference 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.
