Title: Renato Kresch: Innovator in Motion Estimation and Error Diffusion
Introduction
Renato Kresch is a notable inventor based in Haifa, Israel, recognized for his contributions to motion estimation and error diffusion technologies. With a total of 6 patents, Kresch has made significant advancements in the fields of digital imaging and processing.
Latest Patents
One of Kresch's latest patents is titled "Method and apparatus for performing motion estimation in the DCT domain." This invention focuses on determining a motion vector between a current block and a reference block by calculating the exact linear cross-correlation between them. The process involves orthogonally transforming the current block using DCT/DST transforms without prior zero padding, generating a quadruple of transform coefficient blocks. This quadruple is then processed with a reference quadruple to create a block of exact cross-correlations, from which the motion vector is derived.
Another significant patent is the "System and memory-buffer management method for reducing random access memory requirements in error diffusion halftone applications." This invention introduces a quantization technique that reduces the size of the primary error buffer needed for halftoning errors. By decreasing the bin size from 8-bits-per-bin to 2-bits-per-bin for 256 grayscale, the cost of the error diffusion halftoning device is significantly lowered. The method also includes an error diffusion procedure to manage quantization errors effectively.
