Latest Patents

Wai K Cham holds a patent for a method titled "Omission and subsequent estimation of zero sequency coefficients." This method involves dividing a television picture into multiple blocks and applying a two-dimensional unitary transformation to each block. The transform coefficients are then transmitted or stored, allowing for the reconstruction of the original blocks through inverse transformation. To optimize data rates, the zero sequency coefficient is omitted for most blocks, and adjustments are made to minimize visible brightness changes between reconstructed blocks. This innovative technique significantly improves the quality of image transmission.
