Title: The Innovative Contributions of Ruiwen Zhen
Introduction
Ruiwen Zhen is a prominent inventor based in Allen, TX (US), known for his significant contributions to image processing technologies. With a total of 15 patents to his name, Zhen has made remarkable advancements in the field of imaging, particularly in image sharpening techniques.
Latest Patents
One of Zhen's latest patents focuses on image sharpening. This patent discloses various techniques for enhancing images, including a method that utilizes at least one sensor of an electronic device to obtain an image containing visual content. The method generates an edge map that highlights the edges of the visual content within the image. It applies a high-pass signal and an adaptive gain based on the edge map to sharpen the image effectively. Additionally, the method creates a bright halo mask and a dark halo mask, which indicate the upper and lower limits of sharpening, respectively. This innovative approach also modifies the level of sharpening at specific edges to reduce halo artifacts.
Another notable patent by Zhen is related to kernel-aware super resolution. This invention involves an electronic device equipped with at least one imaging sensor and a processor. The imaging sensor captures a burst of image frames, while the processor generates a low-resolution image from these frames. It estimates a blur kernel based on the burst and performs deconvolution on the low-resolution image to create a deconvolved image. Finally, the processor generates a high-resolution image using super resolution techniques on the deconvolved image.
