Abstract:
A hierarchical motion deblurring method for a single image is provided. In the method, a blur kernel of a target image is calculated and a multi-scale representation for representing the target image and the blur kernel is constructed. Then, a gradient attenuation function and a strong edge suppression function are applied to a residual Richardson-Lucy algorithm, so as to iteratively calculate a residual image between the blur kernel and the target image represented by the representation in each scale and restore the residual image to obtain a first restored image and a second restored image. Finally, the two restored images are compared so as to obtain a motion deblurring image.

Abstract:
A fabrication method of a nanomaterial by using a polymeric nanoporous template is disclosed. First, a block copolymer bulk is made from a block copolymer polymerized from decomposable and undecomposable monomers. By removing the decomposable portion of the block copolymer bulk, the polymeric nanoporous template with a plurality of holes is obtained, and these holes have nanostructures with regular arrangement. By exploiting a nanoreactor concept, a sol-gel process or an electrochemical synthesis, for example, is then carried out within the template such that the holes are filled with various filler materials, such as ceramics, metals and polymers, so as to prepare a nanocomposite material having the nanostructure. After removing the polymeric nanoporous template, the nanomaterial with the nanostructure is manufactured.
Abstract:
An image vibration-compensating apparatus and a method thereof are provided. The apparatus and the method are applied in an image-capturing apparatus, such as a digital still camera (DSC) or digital video recorder (DVR), for compensating image vibration when capturing an image. The image vibration-compensating apparatus comprises an adaptive edge extractor, a sub-region movement detector, a frame motion calculator, and a correcting vector generator. The image vibration-compensating apparatus analyses the difference between the current image and the previous image, and outputs the correcting motion vector to achieve the function of image vibration-compensation. In the image vibration-compensating method, an accumulate compensation mode is used to prevent fast motion of an image frame which will cause discomfort of the user's eyes when a relatively large image vibration occurs in a short period.
