Abstract: Embodiments of the disclosure provide a circuit, chip, system, and method for eliminating random perturbation. The circuit includes a weight calculating module for receiving digital signals and random perturbation digital quantity, using least mean square error algorithm to calculate weight deviation iteration coefficient based on digital signal and digital quantity, and updating perturbation weight in real-time according to weight deviation iteration coefficient; and a perturbation eliminating module for eliminating perturbation signal in output digital signal of quantizer according to perturbation weight updated in real-time and updating perturbation weight in real-time according to weight deviation iteration coefficient, and then calculating current perturbation weight in real time to realize self-calibration of perturbation weight.

Abstract: The present application discloses a method and apparatus for digitizing paper data, an electronic device and a storage medium, relating to fields of image processing and cloud computing, in particular to image recognition technologies. The method includes: determining a standard template according to an image to be processed and mark information corresponding to the image to be processed, wherein the image to be processed is obtained by photographing paper data and the standard template is used to represent a reference coordinate system of the image to be processed; recognizing graphic handwriting information comprised in the image to be processed; and generating digitized data corresponding to the image to be processed according to the graphic handwriting information and the standard template.

Abstract: The present application discloses a method and apparatus for digitizing paper data, an electronic device and a storage medium, relating to fields of image processing and cloud computing, in particular to image recognition technologies. According to the solution provided by the present application, graphic handwriting information included in an image to be processed can be recognized, and the handwriting information can be combined with a reference coordinate system of the image to be processed to obtain digitized data, in this way, paper data can still be converted into digitized data even when graphic data is included in the paper data.
