Introduction
Ping Zhu is an accomplished inventor based in San Jose, California. He has made significant contributions to the field of video processing and image signal transformation. With a total of three patents to his name, Zhu's work showcases his expertise and innovative thinking.
Latest Patents
One of Ping Zhu's latest patents is a noise filter for video processing. This invention includes a block selector, a cost calculator, a cost table, a cost comparator, and a coefficient filter. The block selector receives data from the quantization unit and selects blocks for additional filtering. The cost calculator determines a cost for each coefficient in the block using the cost table, and the costs are summed. The cost comparator then compares the total to a threshold, filtering the coefficients using the coefficient filter if the total exceeds a preset threshold. The filtered data is then output to the VLC unit.
Another notable patent is related to the discrete cosine transform and inverse discrete cosine transform (DCT/IDCT) of image signals. This invention describes a DCT/IDCT module that includes a plurality of different cores. One embodiment of a core features two sets of lookup tables to provide multiplication and addition operations for the DCT and IDCT functions. Other embodiments may include one set of lookup tables or none at all. This DCT/IDCT module provides forward DCT and IDCT functionality without the need for additional multipliers.
