Provided is a method and apparatus for deblurring a non-uniform motion blur in an input image, that may restore a clearer image by dividing a large scale input image into tiles corresponding to partial areas, selecting, among the divided tiles, an optimal tile for a partial area most suitable for estimating non-uniform motion blur information, and effectively removing an artifact in an outer portion of a tile through padding of each tile.

摘要:
A method and apparatus for robust estimation of a non-uniform motion blur that may reduce an amount of the non-uniform motion blur information, that is, a number of homographies by estimating non-uniform motion blur information about a blur in a predetermined area, thereby reducing an amount of time needed to remove the non-uniform motion blur, and may improve accuracy and stability of the non-uniform motion blur information by estimating homographies for an input image while increasing a number of the homographies, iteratively.

A method and apparatus for deblurring a non-uniform motion blur using a multi-frame including a blurred image and a noise image is provided. The apparatus may provide a clearer image by estimating non-uniform motion blur information of the blurred image using the multi-frame, and performing estimation of the non-uniform motion blur information and obtaining of a latent image iteratively, thereby improving accuracy for estimating the non-uniform motion blur information, and reducing a processing time.

A method and apparatus for processing an image for enhancing an image quality captured in a low illumination environment is disclosed. The method for processing the image may include estimating motion information based on a base frame among input frames captured using a short exposure time and high ISO sensitivity conditions, removing noise of the base frame using the motion information, and enhancing an image quality of the base frame from which the noise has been removed using a reference frame captured under a long exposure condition.

Provided is an apparatus and method for extracting feature information of an image using a scale-invariant feature transform (SIFT) algorithm. The apparatus may include a first interface configured to generate one or more tile images from a first source image stored in a particular memory, such as a high-capacity short-term memory, and a feature information extractor configured to receive the generated one or more tile images and to respectively extract feature information from each of the one or more input tile images, where the first interface may be configured to generate the one or more tile images by selectively dividing the first source image into the one or more tile images based on a horizontal resolution of the first source image.
