  • Publication number: 20230043408
    Abstract: An image generation method obtains an original image. A character area, a background area, and a position of each flawless character in the original image are determined. The character area is segmented to obtain a first image of each flawless character. A background is removed from the first image to obtain a second image. First image processing is performed on the second image to obtain a third image. Second image processing is performed on the second image to obtain fourth images. Third image processing is performed on the fourth images respectively to obtain fifth images. A similarity between each fifth image and the third image is calculated. When the similarity is greater than a defect threshold, a background image is segmented. Brightness of the background image is adjusted. The target fourth image and adjusted background image are synthesized. The method can generate images with defective characters quickly.

  • Publication number: 20230009689
    Abstract: A boot method for an embedded system is provided. The embedded system includes two mainboards each provided with a baseboard management controller (BMC), a non-volatile memory unit and a network adapter. When the embedded system is turned on, each of the BMCs performs a boot procedure, and then loads an operating system (OS) image file from a corresponding non-volatile memory unit to execute an operating system. When one BMC fails to load the OS image file or to execute the operating system, the BMC causes the corresponding network adapter to communicate with the other network adapter to acquire the OS image file from, the non-volatile memory unit on the other mainboard, so as to replace the OS image file in the corresponding non-volatile memory unit, and directly loads the OS image thus acquired to execute the operating system.
