Abstract: A voice processing method is provided. The method includes: An electronic device first performs de-reverberation processing on a first frequency domain signal to obtain a second frequency domain signal, performs noise reduction processing on the first frequency domain signal to obtain a third frequency domain signal, and then performs, based on a first voice feature of the second frequency domain signal and a second voice feature of the third frequency domain signal, fusion processing on the second frequency domain signal and the third frequency domain signal that belong to a same channel of first frequency domain signal, to obtain a fused frequency domain signal. In this case, background noise in the fused frequency domain signal is not damaged, thereby effectively ensuring stable background noise of a voice signal obtained after voice processing. In addition, an electronic device, a chip system, and a computer-readable storage medium are provided.

Abstract: A disparity image fusion method for multiband stereo cameras belongs to the field of image processing and computer vision. The method obtains pixel disparity confidence information by using the intermediate output of binocular disparity estimation. The confidence information can be used to judge the disparity credibility of the position and assist disparity fusion. The confidence acquisition process makes full use of the intermediate output of calculation, and can be conveniently embedded into the traditional disparity estimation process, with high calculation efficiency and simple and easy operation. In the disparity image fusion method for multiband stereo cameras proposed by the method, the disparity diagrams participating in the fusion are obtained according to the binocular images of the corresponding bands, which makes full use of the information of each band and simultaneously avoiding introducing uncertainty and errors.

Abstract: The present invention provides a process for purifying methionine. A methionine product having a purity of up to 99% or higher is obtained by separating methionine from a salt by-product through a process comprising adsorption and desorption using a macroporous adsorption resin, where the methionine content in the salt by-product is ?0.03%. The yield of methionine extracted with the resin is up to 98% or higher. By using the process of the present invention, the existing production process is simplified, the quality of the methionine product is improved, and the production costs for methionine are reduced.
