Title: Shmuel Farkash: Innovator in Image Compression Technology

Introduction

Shmuel Farkash is a notable inventor based in Haifa, Israel. He has made significant contributions to the field of image compression technology. His innovative work has led to the development of a unique patent that enhances the efficiency of image data processing.

Latest Patents

Farkash holds a patent for an "Image compression coder having improved scale factor control." This invention discloses an image compression coding device that transforms time domain image data into frequency domain data. The compression process involves multiplying the frequency domain data by quantization coefficients, which are scaled based on a non-linear relationship of log(ACVdata) versus log(SF). The method includes making one or more statistical passes through the frequency domain data using initial scale factors to obtain ACV data based on the newly defined relationship. The New Scale Factor (NSF) is then calculated using the initial scale factors, the accumulated code volumes for the two scale factors, and the target code volume (TCV) of the compressed file.
