Introduction

Robert Chihsung Yen is an accomplished inventor based in Novi, MI (US). He has made significant contributions to the field of document image compression, holding 2 patents that showcase his innovative approach to data processing.

Latest Patents

One of his notable patents is a document image compression system and method. This system utilizes a discrete transform image data compression technique where frequency transform coefficients are modified according to a matrix of quantizer values. It employs a predefined plurality of quantization matrices to adaptively select, on a document-by-document basis, an approximate memory packet size for each document's compressed image data storage. The selection of quantization matrices is based on the packet size estimate obtained for each document image. Additionally, the system generates contrast reduction and gray level stretch remapping curves as a function of global image data characteristics, such as the gray level histogram of the document image data. These remapping curves are utilized to preprocess the image data for more effective data compression.
