Abstract:
A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.

Abstract:
Provided is an apparatus and method for super-resolution enhancement processing. The apparatus includes a low-resolution image capturing unit, a patch pair generating unit, a patch pair database, and a high-resolution image reconstructing unit. The low-resolution image capturing unit captures a low-resolution image. The patch pair generating unit divides each of a plurality of high-resolution images into patches and generates a plurality of patch pairs composed of medium-frequency patches and high-frequency patches for the patches. The patch pair database stores the plurality of patch pairs generated by the patch pair generating unit. The high-resolution image reconstructing unit divides the low-resolution image into patches, searches in the patch pair database for a patch pair including a medium-frequency patch that is similar to that of the low-resolution image, and generates a reconstructed high-resolution image by inserting a high-frequency patch included in the found patch pair into a corresponding patch of the low-resolution image.
Abstract:
A method and apparatus for encoding and/or decoding image data. The encoding method includes: if the color space of an image is a single color space, correcting pixel values by applying identical correction pixel values to all color components of a previous image, and if the color space of the image is not a single color space, correcting pixel values by applying different correction pixel values to the color components of the previous image; performing temporal prediction encoding of a current image by using the corrected pixel values of the previous image; quantizing the prediction encoded data; and generating a bitstream by entropy encoding the quantized data. According to the method and apparatus, when the pixel values of a previous image are desired to be corrected in order to perform temporal prediction encoding, different pixel value correction methods are applied according to whether or not the characteristics of color components included in the color space of the image desired to be encoded. By doing so, when image data is encoded, the encoding can be performed adaptively to a variety of color spaces and higher compression efficiency can be maintained.

A golf ball has a thin intermediate layer, within specified thickness and hardness, situated between a ball core and cover layer. The thin intermediate layer provides for a ball having superior ball spin performance without loss of ball speed. Particular compositions for the intermediate layer, along with methods for spray-coating of a ball core and grinding down of a thick intermediate layer that are particularly suited for making this thin intermediate layer, also are disclosed.
Abstract:
Provided is a field effect transistor including an insulator-semiconductor transition material layer. The insulator-semiconductor transition material layer selectively provides a first state where charged holes are not introduced to a surface of the insulator-semiconductor transition material layer when a gate field is not applied and a second state where a large number of charged holes are introduced to the surface of the insulator-semiconductor transition material layer to form a conductive channel when a negative field is applied. A gate insulating layer is formed on the insulator-semiconductor transition material layer. A gate electrode is formed on the gate insulating layer to apply a negative field of a predetermined intensity to the insulator-semiconductor transition material layer. A source electrode and a drain electrode are disposed to face each other at both sides of the insulator-semiconductor transition material layer so that charge carriers can flow through the conductive channel while the insulator-semiconductor transition material layer is in the second state.
