Title: The Innovations of Choong-woong Lee
Introduction
Choong-woong Lee is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of image processing, particularly in the area of de-blocking methods and apparatuses. His work is essential for improving the quality of decoded images, which is crucial in various applications.
Latest Patents
Choong-woong Lee holds a patent for a de-blocking method and apparatus. This invention involves a block classifier that determines whether the received decoded image is a planar surface or a complex surface. A first correction value calculator computes correction values for block boundary pixels using a first filtering coefficient when the decoded image is a planar surface. An interpolator then provides first correction values for pixels on the block boundary. Additionally, a second correction value calculator calculates second correction values for some block boundary pixels using a second filtering coefficient when the decoded image is a complex surface. The corrector then provides a corrected image by applying the appropriate correction values based on the type of surface. This innovative approach effectively removes blocking artifacts, preventing discontinuity between boundaries of the decoded image while maintaining the edge and texture of the image.
