Latest Patents
Jin Zhou's latest patents include a "Method for Image Denoising" and a "Compact Plug-in Noise Cancellation Device." The method for image denoising involves several critical steps. It begins with estimating the noise level of a noisy image based on its smooth blocks. The original image is divided into small blocks, which are then converted from a two-dimensional matrix to a one-dimensional array. These vectors are grouped, and a matrix recovery process using principal component analysis (PCA) is performed to effectively remove the noise. The denoised vectors are then converted back to blocks, allowing for the reconstruction of a higher quality image.
The compact plug-in noise cancellation device (NCD) consists of a microphone, an analog-to-digital converter, a digital-to-analog converter, a rechargeable battery, and a processor. This device acquires audio input from external devices such as stethoscopes or cell phones. The analog data is converted into digital signals, which are processed by the processor. The processor executes various functions, including preprocessing, short-term Fourier transform (STFT), adaptive filtering, inverse STFT, and signal synthesis, to achieve effective noise cancellation.
