Latest Patents

One of Jiann-Der Lee's latest patents is a "Method of block matching-based motion estimation in video coding." This invention aims to reduce redundant information among successive frames in video compression applications. The method allows for the replacement of blocks in the current frame with neighboring blocks from the previous frame, minimizing errors. The New Cellular Search (NCS) Algorithm, a type of Block Matching Algorithm, employs specific search patterns to optimize the search for the best motion vector. Performance measurements such as peak signal to noise ratio (PSNR), Average Search Point (ASP), and Mean Square Error (MSE) are utilized to compare the NCS with other major motion estimation methods, demonstrating its efficiency in computation reduction while maintaining high image quality.

Another significant patent is a "Method for manufacturing artificial implants." This invention outlines a process that begins with acquiring three-dimensional volume images before and after surgery. The method involves aligning these images to generate a difference image, which is then used to create a three-dimensional model of the incised part. Finally, an artificial implant is manufactured to match the shape of the incised area, showcasing Jiann-Der Lee's innovative approach to medical technology.
