Latest Patents

Yi Zhang holds a patent for a method titled "Method of analyzing motion blur using double discrete wavelet transform." This method involves processing a motion-blurred image captured by an imaging device to recover a latent sharp image. The process includes capturing a motion-blurred image signal, computing a two-dimensional wavelet transform of the signal, and performing autocorrelation analysis to estimate the blur kernel. By analyzing the blur kernel, the method determines the length and direction of the blur at each pixel location. Additionally, the method incorporates denoising techniques and reconstructs discrete wavelet transform coefficients to recover the sharp image through an inverse discrete wavelet transform.
