Abstract: A method for decoding an image according to the present invention comprises the steps of: restoring a residual block by performing inverse quantization and inverse transformation for the entropy-decoded residual block; generating a prediction block by performing intra prediction for a current block; and restoring an image by adding the restored residual block to the prediction block, wherein the step of generating the prediction block further comprises a step for generating a final prediction value of a pixel to be predicted, on the basis of a first prediction value of the pixel to be predicted, which is included in the current block, and of a final correction value that is calculated by performing an arithmetic right shift by a binary digit 1 for a two's complement integer representation with respect to an initial correction value of the pixel to be predicted. Thus, the operational complexity during image encoding/decoding can be reduced.

Abstract: Disclosed is a method of estimating a position by a position estimation system. The method includes generating a time-synchronization signal for position determination using a genetic algorithm, embedding the generated time-synchronization signal in an audio signal, and replaying the audio signal embedded with the time-synchronization signal through a speaker, receiving the audio signal embedded with the time-synchronization signal in a microphone, calculating a time delay value of the time-synchronization signal embedded in the received audio signal, and estimating a position of the microphone based on the calculated time delay value.
