摘要： Disclosed is AA′ graphite with a new stacking feature of graphene, and a fabrication method thereof. Graphene is stacked in the sequence of AA′ where alternate graphene layers exhibiting the AA′ stacking are translated by a half hexagon (1.23 Å). AA′ graphite has an interplanar spacing of about 3.44 Å larger than that of the conventional AB stacked graphite (3.35 Å) that has been known as the only crystal of pure graphite. This may allow the AA′ stacked graphite to have unique physical and chemical characteristics.

摘要： An MPEG-4 encoder utilizing an H.263 multimedia chip. The MPEG-4 encoder includes a DC (Direct Current) predictor for predicting a DC component of the image frame encoded by an H.263 standard upon receiving a prescribed MPEG-4 quantization value, and an MPEG-4 reconstruction image memory for converting the H.263 reconstruction image into an MPEG-4 reconstruction image, and storing the MPEG-4 reconstruction image. The MPEG-4 encoder removes spatial redundancy from source image data entered in frame units using a prescribed H.263 quantization value, predicts a DC component of an image frame having no spatial redundancy using a prescribed MPEG-4 quantization value, performs a VLC (Variable Length Coding) process on the image frame using the predicted DC component, and outputs the VLC-processed image frame in the form of an MPEG-4 bit stream. The MPEG-4 encoder reconstructs the image frame having no spatial redundancy, stores the reconstructed image frame, converts the reconstructed image frame into an MPEG-4 frame, stores the MPEG-4 frame, compares the stored image frame with a newly-entered next frame, and removes temporal redundancy according to a result of the comparison.

摘要： Disclosed is a method for encoding a video signal through discrete cosine transform (DCT) and motion estimation (ME) and an apparatus therefor. The method for encoding the video signal simplifies the ME with reference to DCT coefficients. In a method for estimating motion in a video frame compression system using DCT, flatness degrees of the blocks is determined according to the number of DCT coefficients having a non-zero value among DCT coefficients transformed in units of blocks. A reference frame is formed by recovering video frame data from some or all of the DCT coefficients corresponding to the flatness degrees of the blocks. Precision of motion estimation (ME) for a current macro block (MB) of a current video frame is dynamically changed corresponding to the flatness degree of the reference frame.

摘要： An adaptive two-dimensional fast DCT (Discrete Cosine Transform) encoding method capable of encoding an image in a mobile communication terminal, reducing an amount of operations, and reducing power consumption adaptively using a fast DCT method. In a first step, a smoothness (N) of a block image to be processed is determined. Then fast DCT encoding in a row direction for the block image performed and operation values not exceeding the smoothness (N) are output. Next, fast DCT encoding in a column direction for the block image is performed by using result values obtained from the fast DCT encoding operation in the row direction and only operation values not exceeding the smoothness (N) are output.
