Title: Kook-yeol Yoo: Innovator in Variable Length Coding

Introduction

Kook-yeol Yoo is a prominent inventor based in Suwon, South Korea. He has made significant contributions to the field of variable length coding, holding a total of 7 patents. His work focuses on enhancing coding methods and apparatuses, which are crucial for efficient data compression.

Latest Patents

Among his latest patents is a method for variable length coding and decoding that utilizes plural mapping tables. This innovative approach includes a mapper-based variable length coding method that involves several steps. The process begins with receiving symbol data and element type information. It then generates a first code number corresponding to the received symbol data. Following this, a second code number is selected from mapping tables, which are formed based on the first code number and element type information. The method culminates in generating a codeword that corresponds to the selected second code number, ultimately outputting the generated codeword. This invention maintains the advantages of a universal variable length code table while preventing efficiency loss in compression coding.

Another notable patent involves a variable length coding method that dynamically varies the mapping relationship between symbols and bit patterns. This method analyzes occurrence statistics of symbols from selected macroblocks and resets the mapping relationship accordingly. By doing so, it reduces the amount of bits generated when coding images while maintaining the same picture quality.
