Latest Patents

Chang-hoon Yim holds a patent for an interframe wavelet video coding method. This method minimizes the average temporal distance (ATD) in video coding. The interframe wavelet video coding (IWVC) method involves receiving a group of frames and decomposing them into difference frames and first average frames. These frames are processed in both forward and backward temporal directions. The method includes wavelet-decomposing the first difference frames and the first average frames, followed by quantizing the resulting coefficients to generate a bitstream. The IWVC method significantly improves video coding performance.
