Title: Tsen Chung Cheng: Innovator in Image Compression Technologies
Introduction
Tsen Chung Cheng is a notable inventor based in San Marino, CA (US). He has made significant contributions to the field of image compression, holding a total of 3 patents. His work focuses on advanced computational methods that enhance the efficiency of image processing.
Latest Patents
One of his latest patents is titled "System and method for a direct computation of cubic spline interpolation for real-time image codec." This invention presents a cubic spline interpolation (CSI) method and apparatus for image compression through direct computation. The CSI method is designed to work alongside the JPEG standard, resulting in a new CSI-JPEG encoder-decoder (Codec). This invention enables a pipelined compression method that is particularly suitable for hardware or firmware implementations.
Another significant patent is "Fast and efficient computation of cubic-spline interpolation for data compression." This patent describes a method and system for defining a cubic-spline filter and correlating it with a signal to obtain a correlated signal. The process includes autocorrelating the filter to derive autocorrelated filter coefficients, computing a transform of the correlated signal and the autocorrelated filter coefficients, and ultimately obtaining a compressed signal through inverse transformation. The methods described can be applied to one-dimensional or two-dimensional data, utilizing fast Fourier transforms (FFT) or Winograd discrete Fourier transforms (WDFT) with an overlap-save scheme.
