Title: Qing Song: Innovator in Image Processing Technologies

Introduction

Qing Song is a prominent inventor based in Sunnyvale, CA, known for his significant contributions to image processing technologies. With a total of 14 patents to his name, he has made remarkable advancements in the field, particularly in the areas of video signal processing and image data prediction.

Latest Patents

One of Qing Song's latest patents is the "Tensor-product b-spline predictor." This invention involves determining a set of tensor-product B-Spline (TPB) basis functions and generating selected TPB prediction parameters. These parameters are used to create predicted image data in mapped images from source image data, minimizing differences between the predicted and reference image data. The reference images correspond to the source images and depict the same visual content. The selected TPB prediction parameters are encoded in a video signal as part of the image metadata, facilitating the reconstruction and rendering of mapped images on recipient devices.

Another notable patent is the "Electro-optical transfer function conversion and signal legalization." This device includes an electronic processor that defines a first set of sample pixels from received video data according to a first electro-optical transfer function (EOTF). It converts these sample pixels to a second EOTF via a mapping function, producing a second set of sample pixels. The invention also involves determining a backward reshaping function to minimize differences between predicted pixel values from the converted sets.
