Title: Innovator Eun Jin Ko: Advancements in Image Encoding

Introduction

Eun Jin Ko, a talented inventor based in Daejeon, South Korea, has made significant contributions to the field of image encoding. With a total of two patents to her name, Ko focuses on developing innovative methods that enhance the efficiency and quality of image processing.

Latest Patents

Eun Jin Ko's latest patents include two advanced techniques in image encoding. The first patent, titled "Image encoding method using binary partition tree," introduces a method that utilizes a Binary Partition Tree (BPT) to optimize the encoding process. This technique involves detecting blocks in a current frame that have a pixel value discrepancy exceeding a threshold when compared to a reference frame. By applying BPT selectively rather than to all frames, it significantly enhances the encoding speed within P frames and B frames, while maintaining the Peak Signal-to-Noise Ratio (PSNR) within a specific range of the reference frame.

The second patent, "Image encoding method using adaptive preprocessing scheme," outlines an innovative approach that includes determining the encoding type of each frame and adjusting the block size accordingly. This method allows for intra-picture and inter-picture replication preprocessing procedures based on the determined blocks. As a result, image frames undergo a more efficient encoding process, leading to potential enhancements in both speed and quality.
